Thanks for the replies.

(1) Of course he showed 33. A bit of overthinking/wishful thinking ('he can't have 77 now'; 'I counterfeited QJ now.' etc)

(2) He either has KQ (not very likely), or he bet his set at the flop (but why no reraise then?), or he semi-bluffed J9/98 (very likely). Don't think reraising the turn is optimal here.

(3) Does anyone not pay off TT/JT/KJ here? He showed JT, I split with runner-runner Kings

(4) I actually think this was the perfect play.. I'm losing 1 bet to a set/flush anyway, so this maximizes my profit against lesser hands. Results: Villain showed 22.

(5) Villains showed AA & KK. Wanted the first player out with KQ/QJ/flushdraw.

(6) Shorty had AcKs :P
