In what circumstances will a pro se litigant waive appellate review of the district court's treatment of his remaining claims?

papers filed by pro se litigants," id. at 118 n.1, we have also recognized that the degree of solicitude due to pro se litigants is "lessened" in situations where, as here, the litigant has previous legal experience, see Tracy v. Freshwater, 623 F.3d 90, 102 (2d Cir. 2010).

Here, aside from his due process claim, Blasi - a former attorney with years of litigation experience - asserts only that "there was sufficient evidence to deny [the defendants'] summary judgment motion." He has advanced no specific arguments in support of this assertion, nor has he called our attention to the specific "evidence" upon which his assertion is based. Accordingly, we conclude that he has waived appellate review of the district court's treatment of his remaining claims. Cf. Krist v. Kolombos Rest. Inc., 688 F.3d 89, 98 (2d Cir. 2012) (finding a challenge to the dismissal of a claim to be abandoned where an appellate brief "contain[ed] no authority or argument as to how the court erred in dealing with [a] claim").
