I played the following interesting (and for me unfortunate) hand online last night and would welcome any comments.

3 handed $2.50-5 game

SB: Villain $560 stack
BB: Big Blind $1792 stack
Button: Hero $725 stack

Villain is a tough, very aggressive reg who is capable of making some unusual plays.

Pre-flop: Hero on button has KdJd. Hero raises to $13. Villain in SB 3 bets to $49. Big Blind folds. Hero calls the $49 bet.

Flop: Flop is 10s9d3d. Pot is $102. Villain bets $42. Hero raises to $137. Villain calls.

Turn: Turn is 5s. Pot is $376. Villain checks. Hero bets $377. Villain calls $377 and is all-in.

River: River is Ah. Villain shows KcQd and takes the pot.

I have been thinking about the hand and do not know what to make of Villain's call. Perhaps to him my ranges are really unbalanced in these spots (my aggressive lines consist of too many flush draws and QJ and too few value combos). If Villain sees my value combos as only A10, 109 suited and 33 (assuming I 4 bet AA-JJ, 1010 and 99 preflop) that is 17 combinations. If Villain sees the draws I would play aggressively as consisting of AJd,, A8-A4d, A2d, KQ, KJd, QJ suited, J8 suited, 87d and 86d that is 26 combos (assuming I 4 bet AKd preflop and accounting for the KcQd in his hand). I ran the math on this and against this range he has 16.9 outs and he needs 14.67 outs to make the call (again accounting for the KcQd in his hand). I took KQ and J8 suited out of my range and ran the math again; against my revised range he has 13.07 outs.

So on balance it looks like he made a really sick call! We have a history of very aggressive play versus each other and he is not one to back away from a confrontation. In terms of learning from this hand, I think I should move some draws out of the range I will play aggressively and move some top pair and other combos in (for example K10 suited and 98 suited). Perhaps I should also just flat his three bet sometimes with hands like JJ, 1010 and 99; I have been always 4 betting these hands against him pre; while I am pushing some equity pre versus him with these holdings he is obviously adjusting well to the absence of these hands in my range post flop when I do not 4 bet pre.

I would appreciate any thoughts or comments. Thank you!
