    OPINION
    CHIEF JUSTICE SAYLOR                                                   DECIDED: June 20, 2017
    This is a capital post-conviction appeal.
    On September 23, 2003, Appellant forcibly entered the Berks County home of
    Greta A. Gougler, where he robbed, raped, and murdered her. Appellant was arrested,
    tried, and convicted for first-degree murder, rape, robbery, and other offenses, and a
    jury returned a death verdict in a capital sentencing proceeding. On direct appeal, this
    Court affirmed. See Commonwealth            v.   Pruitt, 
    597 Pa. 307
    , 
    951 A.2d 307
    (2008).
    In   2009, Appellant commenced the present proceedings under the Post
    Conviction Relief Act, 42 Pa.C.S. §§9541-9546 (the "PCRA"). The post -conviction court
    conducted    a        series   of   evidentiary hearings, throughout which        Appellant   was
    represented by the members of the Federal Community Defender Office.                   Later, per
    Appellant's request, those attorneys were removed from the representation and current
    counsel was appointed in their place.
    In   2015, Appellant submitted a request to proceed pro se.           The PCRA court
    scheduled a proceeding, at which Appellant agreed to continue to be represented by
    counsel but was deemed by the court to have "knowingly, intelligently and voluntarily
    abandon[ed] any issues raised by prior PCRA counsel and/or [current counsel] that are
    not contained in [a] memorandum in support of the PCRA relief petition filed this date[.]"
    N.T., Nov. 23, 2015, at 9-10.
    The PCRA court subsequently denied relief on the remaining claims for relief.
    This appeal followed, in which Appellant advances six challenges, several of which fall
    within the category of the claims deemed to have been abandoned by the PCRA court.
    Part   I
    Appellant's first three claims, pertaining to DNA evidence presented by the
    Commonwealth at trial, were found by the PCRA court to have been preserved. The
    relevant background is as follows.
    At trial, the prosecution offered several primary lines of evidence to address
    Appellant's identity as the robber, rapist, and killer, as well as the actus reus of the rape.
    First, Appellant's confession to police was introduced, in which he admitted to having
    forcibly entered Ms. Gougler's home and inflicting physical violence upon her, albeit that
    he denied any intention to kill and maintained that he did not rape the victim. See N.T.,
    Apr. 25, 2005, at 174-177.          The Commonwealth also presented testimony from a
    witness to whom Appellant had confessed, extra-judicially, to having perpetrated the
    physical acts resulting in the victim's death.               See N.T., Apr. 26, 2005, at 247-48
    (testimony of Sean Peterson).
    In a   second category of evidence, a forensic pathologist testified that the victim
    had been beaten severely and subjected to ligature strangulation.            See 
    id. at 355-365.
    In   terms of the rape, the pathologist explained that the victim suffered lacerations and
    [J-1-2017]     -   2
    other injuries to her vagina and anus consistent with nonconsensual penetration. See
    
    id. at 352-355,
    364. Police officers also attested that the victim's body was naked when
    discovered. See, e.g., N.T., Apr. 25, 2005, at 22, 31.
    In   the third set of evidence, the Commonwealth sought to confirm the fact of the
    rape, and Appellant's identity as the rapist, through testimony establishing a match
    between Appellant's DNA and a sample of genetic material taken from the inner thigh of
    the victim's body.    In   this regard, crime -laboratory serologist Michael Brincat testified
    that this evidence sample contained both blood and sperm cells. See N.T., Apr. 26,
    2005, at 290-291. Pennsylvania State Police ("PSP") forensic scientist Lisa Mihalacki
    then testified that she segregated the sample into male and female components and
    conducted DNA analysis. According to the witness: "Every genetic marker, every place
    that we checked from this sample and [Appellant's] were identical to each other,"
    resulting in between a one in 1.5 billion and a one in 39 billion chance that another
    person might have contributed the sample (with the variation accounted for by racial
    differences within the population).     
    Id. at 313-314.1
         On cross-examination, Appellant's
    1 The DNA analysis discussed at trial and in the post -conviction proceedings was
    presented in the form of numerical expressions of the length of repeat DNA sequences
    found at discrete locations, or loci, on a chromosome. At each locus, testing generally
    produces measurements for two DNA fragments, or allele, one contributed by each of
    the subject's parents.      See N.T., Apr. 26, 2005, at 316-17.         See generally
    Commonwealth v. Blasioli, 
    552 Pa. 149
    , 154-58,

    MCCORMICK ON EVIDENCE §205 (2013) (explaining the use of DNA profiling to detect the
    number of repeats, at given locations, for different alleles on a graph known as an
    electropherogram).
    For example, the expression "D135317 11, 12," taken from Ms. Mihalacki's report as it
    concerns the male component of the evidence sample taken from the victim's thigh,
    signifies that, at the loci denominated D135317, a particular genetic sequence repeated
    itself 11 times in one of two DNA fragments, and 12 times for the other.
    [J-1-2017]   -   3
    lawyer initially pointed out that the DNA data reflected that there was more than one
    contributor to the portion of the evidence sample denominated as the male component.
    See 
    id. at 316-320.2
              The remainder of the cross-examination focused on racial
    differences in the population samples and the handling of the evidence samples.           See
    
    id. at 320-323.
    In    the post -conviction proceedings, Appellant contended that there were multiple
    flaws in the Commonwealth's DNA analysis and that his trial counsel were derelict in
    failing to apprehend and capitalize upon such deficiencies.3           In   support, Appellant
    presented testimony from Randal T. Libby, PhD, a forensic geneticist.               Dr. Libby
    testified that the "male" component of the evidence sample taken from the victim's thigh
    was of a low -template quality and, accordingly, generated a great deal of subjectivity in
    interpreting the testing result. See, e.g., N.T., Aug. 21, 2013, at 32-38, 59, 62, 64-65,
    80.4
    Indeed, it was Dr. Libby's opinion that the sample contained insufficient DNA to
    yield a reliable analysis. See 
    id. at 51,
    87. This, the geneticist explained, was reflected,
    inter alia,   in the   absence of any data whatsoever in Ms. Mihalacki's report pertaining to
    2 As noted, ordinarily, each genotype found at a particular chromosomal location will
    generate two numbers, one deriving from the DNA strand inherited from the
    contributor's mother and one from the father. See supra note 1. However, several of
    the genotypes reflected in Ms. Mihalacki's report assigned to the female component of
    the evidence sample taken from the victim's thigh contained more than two numbers,
    thus indicating the presence of multiple contributors.
    3Appellant was represented at trial by two attorneys, one of which took the lead at the
    guilt phase. See N.T., Dec. 19, 2013, at 1049.
    4 See generally Erin Murphy, The Art in the Science of DNA: A Layperson's Guide to the
    Subjectivity Inherent in Forensic DNA Typing, 58 EMORY L.J. 489, 503-08 (2008)

    in DNA analysis of low -template samples).
    [J-1-2017] - 4
    alleles at three loci for the male evidence sample. See 
    id. at 54,
    65-66. Additionally,
    Dr. Libby affirmed          that this report itself indicated that results at five loci were
    "[i]nconclusive due to an insufficient amount of DNA." 
    Id. at 62-63.
    Dr. Libby also found the interpretive enterprise to have been further complicated
    by the obvious presence of multiple contributors (as was alluded to during cross-
    examination at trial). See 
    id. at 47,
    68-70; see also supra note 2. Moreover, he posited
    that the results of Ms. Mihalacki's analysis in fact suggested that Appellant should be
    excluded as a contributor to the evidence sample. See, e.g., N.T., Aug. 21, 2013, at 51,
    54-55, 95.      It   was also the geneticist's opinion that there were too many inconsistencies
    in the   data to justify the use of a statistical analysis to support the probability estimates
    that Ms. Mihalacki offered in her testimony. See 
    id. at 94.5
    In   terms of Ms. Mihalacki's assertion at trial of a match at every genetic marker,
    Dr. Libby testified that such testimony was demonstrably false according to her own
    report. See 
    id. at 73-75.
             Dr. Libby further attested that the conclusion that the male
    component of the evidence sample contained sperm was unverifiable, since sperm tails
    5 For example, Dr. Libby observed an inconsistency in Ms. Mihalaki's interpretive
    assumptions pertaining to potentially homozygous alleles. In this regard, assuming a
    robust sample of genetic material, where a single allele is detected at a particular
    location, it is generally appropriate to assume the subject has two of the same alleles at
    that location, which are termed homozygous. See N.T., Aug. 21, 2013, at 45.
    The inconsistency in assumptions arose as follows. At one locus Ms. Mihalaki assumed
    that the genotype for the evidence sample was homozygous because the testing
    revealed a single length allele; whereas, at another locus, Ms. Mihalaki assumed that a
    result reflecting a single length allele was incomplete. See 
    id. at 64.
    Notably,
    Appellant's genotype reflected two different alleles at the marker location, thus
    indicating a mismatch (and concomitant exclusion of Appellant as a contributor to the
    evidence sample), were the evidence sample alleles to be deemed homozygous.
    Dr. Libby opined that there was no scientific reason, nor anything appearing in the
    scientific data, to explain Ms. Mihalaki's shifting assumptions. See 
    id. at 64-65.
    [J-1-2017]   -   5
    were undetectable upon microscopic examination. See 
    id. at 75-79.
    Finally, Dr. Libby
    noted that data from Ms. Mihalaki's initial analysis of the evidence sample, which she
    apparently had discounted in favor of further testing, had resulted in an affirmative
    exclusion of Appellant as a possible contributor to the evidence sample. See 
    id. at 133.
    In   this regard, Dr. Libby suggested that Ms. Mihalaki's methodology conflicted with the
    scientific norm of reproducibility. See 
    id. at 130-134.
    Appellant also presented testimony from his lawyer primarily responsible for his
    representation at the guilt phase of trial.              The attorney testified that he was not
    significantly concerned with the DNA evidence, because the Commonwealth already
    had adduced compelling physical evidence demonstrating the fact of rape via the
    testimony of a forensic pathologist, and moreover, "there was only [Appellant] in the
    room."     N.T., Dec. 19, 2013, at 1201; see also 
    id. at 1196
    ("[A]ll the DNA did was
    identify, really identifying [Appellant] as the person who committed the rape. But, you
    know, the fact of the rape was there, though, and there was no evidence of anybody
    else being there, so   I   didn't think   it   added much."); 
    id. at 1219.
    Counsel explained that
    he did not wish to draw undue attention to evidence that he considered unimportant.
    See 
    id. at 1202.
    Nevertheless, the lawyer affirmed that the Commonwealth's DNA evidence
    presented a strong indication of Appellant's culpability for rape.                 See 
    id. at 1208.
         In
    spite of such materiality, counsel testified that he did not understand the data in Ms.
    Mihalaki's report and merely relied on her representation of a genetic match between
    the evidence sample and the sample taken from Appellant.                        See 
    id. at 1207.
         With
    reference to the data reflected in the report, the attorney also indicated:              "I   don't imagine
    any lawyer would know how that got from A to             B       or what that means." 
    Id. at 1208.
    [J-1-2017]   -   6
    A. Failure to Investigate, Effectively Cross-examine, and Present an Expert
    Presently, based on the above, Appellant contends that his counsel failed to
    conduct a professionally reasonable investigation and rendered deficient stewardship at
    trial. Appellant argues that, at a minimum, his trial counsel had an obligation to garner
    at least some rudimentary understanding of the evidence being used against him.                 He
    also takes the position that counsel should have consulted with and presented
    testimony from a defense expert.      See Brief for Appellant at 16-17 (collecting cases).
    According to Appellant, trial counsel "essentially conducted the cross-examination of the
    Commonwealth's DNA expert on the fly." 
    Id. at 15.
                 In   terms of the materiality of the
    DNA evidence and its prejudicial impact, Appellant couches it as the "sole forensic
    evidence linking [him] to the crime" and posits that it played a pivotal role at trial. 
    Id. at 16.
      He concludes that there is a reasonable probability that the jury would have found
    reasonable    doubt    to   exist   had     counsel        investigated    and    challenged   the
    Commonwealth's DNA evidence in an effective manner.6
    At the outset, we find arguable merit in Appellant's challenge to his lawyer's
    stewardship and conclude that counsel could have had no reasonable strategy to
    support his failure to gain a better understanding of Ms. Mihalaki's report.' Contrary to
    6The Pennsylvania test for ineffective assistance of counsel is, in substance, the same
    as the two-part performance -and -prejudice standard set forth by the United States
    Supreme Court, see Strickland v. Washington, 
    466 U.S. 668
    , 687, 
    104 S. Ct. 2052
    ,
    2064 (1984), although this Court has divided the performance element into two sub-
    parts dealing with arguable merit and reasonable strategy. Accordingly, to succeed on
    an ineffectiveness claim, a petitioner must establish that: the underlying legal claim has
    arguable merit; counsel had no reasonable basis for her action or inaction; and the
    petitioner suffered prejudice as a result. See Commonwealth v. Pierce, 
    515 Pa. 153
    ,

    performed and the inferences that one could logically draw from the results" linking his

    counsel's comment that no lawyer would apprehend the underlying data, see N.T., Dec.
    19, 2013, at 1208, the present record reflects that Appellant's post -conviction lawyers
    amply comprehend it, including the multiple problems stemming from Ms. Mihalaki's
    interpretation of a partial genetic profile taken from a low -template evidence sample.8
    Moreover, counsel's failure to appreciate -- and exploit -- the fact that the data in Ms.
    Mihalaki's initial report apparently indicated an affirmative exclusion of Appellant as a
    contributor to the male evidence sample, see N.T., Aug. 21, 2013, at 133-134, is simply
    inexplicable. To the degree that counsel was unable to understand the test results on
    his own, plainly he should have consulted an expert.9
    Given the potency of DNA evidence, see, e.g., McDaniel     v.   Brown,

    stage. Accord N.T., Dec. 20, 2013, at 1298 (reflecting the attestation of Appellant's trial
    counsel that Appellant consistently confirmed the facts that he had related to the police,
    which included his perpetration of a violent attack upon the victim). Although Appellant
    did not admit to having perpetrated the rape, the fact of such crime was apparent from
    the physical evidence, and Appellant has never provided any plausible explanation that
    would persuasively suggest any other person's involvement in the relevant events that
    took place in the victim's house. Accord N.T., Dec. 20, 2013, at 1298 (memorializing
    trial counsel's testimony that Appellant never indicated that anyone other than he and
    the victim was present during their encounter).1° For these reasons, in our considered
    judgment   - while trial counsel should have provided       more able stewardship relative to
    the DNA    evidence - Appellant has not established         a reasonable probability that the
    verdict would have been different had counsel done so, i.e., a probability sufficient to
    1°  At the post -conviction stage, Appellant did adduce some evidence that Appellant was
    in the presence of a Hispanic man when he decided to "get more money," presumably
    in a timeframe in temporal proximity to the murder. See N.T., Jan. 16, 2014, at 1452-
    1453. Moreover, trial counsel affirmed that, after the murder, a "tipster" apparently had
    reported to police that he had seen black and Hispanic males in the victim's yard on the
    night of the killing. N.T., Dec. 20, 2013, at 1198-1199. No evidence was introduced at
    trial or in the post -conviction proceedings, however, to the effect that a second intruder
    ever entered the victim's house, and Appellant does not make any allusion to such a
    person in the present briefing.
    Justice Wecht takes the opportunity to explain that the burden at trial was never on
    Appellant to suggest another's involvement in the crimes. See Dissenting Opinion, slip
    op. at 10. As we have indicated, however, in the present posture of the case            -
    on
    review of claims of deficient stewardship at the post -conviction stage -- the burden lies
    squarely with Appellant. See supra note 6.
    As also discussed above, the circumstantial evidence of Appellant's perpetration of the
    rape is very strong, again, arising out of his forcible entry into the victim's residence and
    his otherwise brutal treatment of the victim, and in the absence of evidence that any
    other potential perpetrator had entered the home during the time frame in which the
    victim was brutalized, raped, and killed.

    undermine confidence in the outcome of the proceedings. See Commonwealth                 v.   Laird,
    
    632 Pa. 332
    , 343, 
    119 A.3d 972
    , 978 (2015).
    B.   Assertedly False Testimony and Alleged Concealment of Evidence
    In    his second line of argument, Appellant focuses on Ms. Mihalaki's testimony
    that "[e]very genetic marker, every place that we checked from this sample and
    [Appellant's] were identical to each other."   N.T., Apr. 26, 2005, at 313.         According to
    Appellant, he was denied due process and the effective assistance of counsel on the
    basis of this assertedly false attestation.
    Appellant supplements this argument with a series of allegations concerning the
    involvement of a former PSP serologist, Ranae Houtz, in the forensic analysis.
    Appellant explains that trial counsel was aware that Ms. Houtz bore the responsibility for
    submission to the DNA laboratory of the samples taken from the victim, see N.T., Dec.
    19, 2013, at 1209, and that her job performance previously had been questioned by her
    superiors and others, ultimately resulting in her termination.           See 
    id. at 1212-1213.
    Appellant points to one error made by Ms. Houtz in his case, in which she had
    mislabeled one of the evidence samples. See Brief for Appellant at 44-45. Appellant
    also charges that "[t]he testimony of Ms. Mihalacki and Mr. Brincat was crafted to
    conceal the involvement    - and errors - of [Ms.]       Houtz, who was initially assigned to the
    case and who resigned from the [PSP] after repeated errors were detected in her work."
    
    Id. at 43.
       According to Appellant, his lawyers should have sought discovery regarding
    Ms. Houtz's performance, undertaken to have her work reviewed by a defense expert,
    and impeached the testimony of Commonwealth expert witnesses based on Ms.
    Houtz's involvement, which those witnesses failed to disclose to the jurors. See 
    id. at 45
    ("Ms. Mihalacki and Mr. Brincat testified falsely regarding Ms. Houtz's involvement
    [J-1-2017]    -   10
    and error in this case, concealing from the jury that crucial evidence was processed and
    tested by a forensic scientist whose repeated errors forced her resignation and called
    into question her work in over 600 cases.").
    To the degree that Appellant attempts to frame the issue as one of direct trial
    court error, the claim is waived for failure to advance it at trial.               See, e.g.,
    Commonwealth     v.   Keaton, 
    615 Pa. 675
    , 693, 
    45 A.3d 1050
    , 1060 (2012) (explaining
    that an issue is waived "if the petitioner could have raised   it   but failed to do so before
    trial, at trial, during unitary review, on appeal, or in a prior state postconviction
    proceeding" (quoting 42 Pa.C.S. §9544(b)).        Moreover, despite the aspersions cast
    upon the Commonwealth, Ms. Mihalacki's report straightforwardly disclosed, inter alia,
    the absence of data at five loci.    See N.T., Aug. 21, 2013, at 62-63 (reflecting the
    report's admonition that the report itself indicated that results at five loci were
    "[i]nconclusive due to an insufficient amount of DNA"). While clearly she should have
    been more careful in her testimony at trial, affording her the benefit of the doubt, Ms.
    Mihalacki's overstatement may have reflected an attempt to express her belief that
    Appellant's profile matched the evidence sample at the genetic markers for which data
    was present.    Notably, Appellant's own expert recognized that, although there is
    disagreement concerning the scientific validity of such an approach, various laboratories
    will declare DNA matches based on partial profiles. See N.T., Aug. 21, 2013, at 60.11
    With regard to Ms. Houtz, before trial the Commonwealth discussed her
    involvement with defense counsel and explained that the serology testing had been

    repeated by Mr. Brincat.     See, e.g., N.T., Dec. 19, 2013, at 1398-1399.           Mr. Brincat's
    report also indicated -- in bold capital type -- that the relevant samples of genetic
    material had been submitted to the DNA laboratory in October 2002, about five months
    before Mr. Brincat testified that he began his own testing of samples pertaining to
    Appellant's case.     See N.T., Apr. 26, 2005, at 301. This too, then, was information
    readily available to counsel.
    In   terms of the ineffectiveness dynamic, we express reservations concerning trial
    counsel's performance similar to those indicated in our treatment of Appellant's initial
    claim, above.     Plainly, in response to Ms. Mihalacki's assertion of a match at every
    genetic marker incorporated into the testing, counsel should have confronted the
    witness with her own report disclosing missing data at five loci.              Counsel was also
    armed with enough information to disclose Ms. Houtz's involvement in the initial testing
    and in the chain of custody underlying the DNA analysis.
    In   any event, our resolution of the issue again turns on Appellant's inability to
    establish prejudice in light of the compelling other evidence establishing his identity as
    the robber and killer and the fact of a rape, and the absence of any plausible alternative
    theory to discount that Appellant was also the rapist.

    Appellant    next   characterizes the assertedly false testimony and alleged
    concealment of evidence as violations of Napue          v.   Illinois, 
    360 U.S. 264
    , 269, 
    79 S. Ct. 1173
    , 1177 (1959) (holding that the knowing use of false testimony to obtain a
    conviction violates due process), and Brady      v.     Maryland,

    , 1196-97 (1963) (reflecting the obligation, on the part of prosecutors, to disclose
    exculpatory information material to the guilt or punishment of an accused).              Appellant
    catalogues the asserted taints as follows:
    [J-1-2017]   -   12
    The Commonwealth presented Ms. Mihalacki's false and
    misleading testimony that [Appellant's] DNA matched the
    perpetrator's DNA;
    The Commonwealth presented Mr. Brincat's false and
    misleading testimony concealing the involvement of Ms.
    Houtz in preparing samples used in DNA testing;
    The Commonwealth presented Ms. Mihalacki's false and
    misleading testimony concealing the involvement of Ms.
    Houtz in preparing samples used in DNA testing;
    The Commonwealth suppressed evidence that would have
    revealed the false and misleading testimony of Mr. Brincat;
    The Commonwealth suppressed evidence that would have
    revealed the false and misleading testimony of Ms.
    Mihalacki;
    The Commonwealth suppressed evidence that would have
    exposed at least one error by Ms. Houtz during her
    preparation of samples for DNA testing; and
    The Commonwealth suppressed evidence indicating that
    other errors may have been made in the handling and
    testing of the samples.
    We reiterate that the Commonwealth had disclosed to the defense both that the
    evidence sample taken from the victim's thigh resulted in an incomplete DNA profile and
    that Mr. Brincat was tasked with repeating the serology analysis previously undertaken
    by Ms. Houtz.       Particularly since this information was known (or, at the very least,
    should have been known) to counsel, the attorney apparently could have presented at
    trial precisely the same challenges as are reflected in the present briefing. As such, we
    find the instant claim to be unpreserved in its entirety. See Commonwealth v. Cousar,
    Pa.     ,          
    154 A.3d 287
    , 301 (2017) ("Brady claims    .   .   .   may be subject to
    waiver."); cf. Routly   v.   Singletary, 
    33 F.3d 1279
    , 1286 (11th Cir. 1994) ("There is no
    [J-1-2017]   -   13
    violation of due process resulting from prosecutorial non -disclosure of false testimony if
    defense counsel is aware of it and fails to object.").
    Part   II
    The PCRA court deemed all remaining claims to have been abandoned by
    Appellant, who, in the present briefing, vigorously challenges this conclusion.12 With
    reference to the abandonment, the PCRA court conducted a discussion with post -
    conviction counsel and a colloquy with Appellant which unfolded as follows.
    The court had scheduled a proceeding to address Appellant's request to proceed
    pro se. At the outset, the attorney for the Commonwealth announced that the defense
    intended to withdraw all claims for relief pertaining to the penalty phase of trial and
    requested a colloquy to confirm Appellant's wishes.              See N.T., Nov. 23, 2015, at 2.
    Appellant's counsel responded that the parties were in agreement that counsel could file
    a revised memorandum elaborating upon specific claims for relief, and that counsel
    would continue to represent Appellant. See 
    id. at 3.
    In   the ensuing colloquy, Appellant confirmed that he was satisfied for counsel to
    continue with the representation and stated:               "I'm asking for a ruling on the DNA
    evidence; that's the issue I'm asking for the ruling."          
    Id. at 5.
      Counsel then confirmed
    this assertion.   See 
    id. ("We're asking
    for a new trial based upon ineffective assistance
    of counsel in handling the various aspects of the DNA evidence through the course of
    12 Appellant seeks to present three claims in addition to those discussed in Part I,
    above. These include: an allegation of prosecutorial misconduct; a challenge asserting
    due process violations and ineffective assistance in the failure of trial counsel to contest
    the admission of Appellant's pretrial statements; and a final claim of deficient process
    and attorney stewardship relating to counsel's failure to locate and retain a credible
    pathologist to assist the defense.
    [J-1-2017]      -   14
    trial.").    According to the post -conviction lawyer, Appellant was "making a knowing,
    conscious decision to abandon those issues that are not contained in the pages of [the]
    brief" that was to be filed that day. 
    Id. The PCRA
    court read into the record the headings of each issue to be preserved,
    which mirror the titles of the three subparts of Part            I   of this opinion. See 
    id. at 6-7.
    The
    court then told PCRA counsel: "You now have three issues. Three issues. They are all
    DNA related. That's all you need to discuss because the defendant has said that he's
    not pursuing anything else." 
    Id. at 8.
    The court then dictated the following order without
    objection:
    AND NOW, this 23rd day of November, 2015, the Court
    having conducted a colloquy with regard to the status of the
    defendant's amended PCRA petitions with the defendant's
    defense counsel [and the attorney for the Commonwealth],
    we find that the defendant is knowingly, intelligently and
    voluntarily abandoning any issues raised by prior PCRA
    counsel and/or [present counsel] that are not contained in
    the memorandum in support of the PCRA relief petition filed
    this date by [present counsel]. The issues raised in this
    memorandum relate to the DNA evidence presented at trial.
    
    Id. at 9-10.13
    Presently, citing to a decision involving a waiver of the right to counsel, Appellant
    contends that a post -conviction court is required to conduct a specific, "probing
    colloquy" before permitting any claims to be abandoned.                        Brief for Appellant at 61
    (quoting Commonwealth          v.   Starr, 
    541 Pa. 564
    , 581-82, 
    664 A.2d 1326
    , 1335 (1995)).
    13 Seven months after the proceeding, Appellant filed a "Nunc Pro Tunc Statement to
    Correct the Record," asserting that he intended to abandon only penalty -phase claims
    and that all guilt -phase claims should be deemed to be preserved. The PCRA court
    found that no action was necessary on this statement, since "the record of the
    November 23, 2015 colloquy speaks for itself." Memorandum to Clerk of Courts Official
    File dated July 26, 2016, in Commonwealth v. Pruitt, No. 6003-02 (C.P. Berks).
    [J-1-2017]   -   15
    Appellant takes the position that the PCRA court failed to conduct an adequate colloquy
    so as to clarify what issues he was agreeing to forego.          According to Appellant, the
    court proceeding was "rather confusing in its nature," as, for example, it opened with a
    discussion of the abandonment of only penalty -phase issues. 
    Id. at 63.
    Furthermore,
    he asserts that he "expected that the Court would make a decision on his request for
    Summary Judgment on the DNA claims then he would be able to proceed further with
    all guilt phase PCRA issues, if necessary." 
    Id. By way
    of additional support, Appellant
    references Commonwealth       v.   Saranchak, 
    570 Pa. 521
    , 
    810 A.2d 1197
    (2002), as an
    instance in which this Court sanctioned the reassertion of previously abandoned post -
    conviction claims.
    Initially, we differ with Appellant's position that a developed colloquy is an
    essential prerequisite to the withdrawal of some claims presented in a post -conviction
    petition.   To the contrary, the advancement of particular challenges to a judgment of
    sentence is generally considered to be a strategic matter relegated to the sound
    judgment of counsel.    See Jones     v.    Barnes, 
    463 U.S. 745
    , 751-52, 
    103 S. Ct. 3308
    ,
    3313 (1983) ("Experienced advocates since time beyond memory have emphasized the
    importance of winnowing out weaker arguments on appeal and focusing on one central
    issue if possible, or at most on a few key issues."); accord Commonwealth       v.   Jette, 
    611 Pa. 166
    , 184, 
    23 A.3d 1032
    , 1043 (2011).
    Here, we recognize that counsel's strategic calculations may not have been the
    driving force pertaining to the abandonment of at least some of the previously asserted
    claims. For example, there are suggestions on the record that Appellant was opposed
    to pursuing penalty -phase relief.
    Nevertheless, at the time of the relevant proceedings before the PCRA court,
    counsel apparently applied his professional judgment in accommodating his client's
    [J-1-2017]   -   16
    wishes on the subject of abandonment. Although we agree with Appellant that those
    proceedings initially opened with a focus upon the abandonment of penalty -phase
    claims, as reflected above, they took a different turn toward the identification of discrete
    issues that counsel and Appellant agreed were to be pursued, to the exclusion of all
    others.     This approach is expressly manifested in the admonitions and order of the
    PCRA court, to which no contemporaneous objection was lodged.
    With regard to the Saranchak decision, in that case the petitioner had withdrawn
    his post -conviction petition in its entirety.   See 
    Saranchak, 570 Pa. at 523
    , 810 A.2d at
    1198.     We find such scenario to be materially distinct from a winnowing of extensive
    claims presented to a post -conviction court.         In   this regard, again, we also differ with
    Appellant's position that a colloquy is necessary to support foregoing discrete post -
    conviction claims -- indeed, such decisions are routinely made outside of the presence
    of the courts.14
    We conclude that the record supports the PCRA court's determination that
    Appellant abandoned claims other than those addressed in Part of this opinion.
    I
    The order of the post -conviction court is affirmed.
    Justices Baer, Todd, Donohue, Dougherty and Mundy join the opinion.
    Justice Wecht files a dissenting opinion.
    14
    Appellant's categorical abandonment of all penalty-phase claims presents the
    circumstance most analogous to the waiver of all claims at issue in Saranchak.
    Notably, however, Appellant does not seek to advance any penalty -phase issues in this
    appeal.
