S: Flop B33 34% X 66%. Turn B33 76% X 24%. River B33 53% X 47% XC 100% BC 100%.

C: When a river completes the dominant turn draw, don’t pay off just because the sizing is moderate—AK is only a bluff-catcher here, and K♣ also blocks part of the missed-club bluff region.

D: Preflop - good Flop - good. That flop is much better for villains range. Turn - I wonder if we can overbet here. Villain capped his range checking back flop, so we might be able to go large here. River - this is close. I don’t mind the call but would t hate a fold either.

C: AK is still a pure river bluff-catch call after checking—the 4 completes straights, but at this sizing I need only ~23%, and solver says my range is too strong to overfold.
