Home game hand quiz. What did he have?

[theWhale]

Played a home game on Saturday and only 3 of us showed up.

Unfortunately, it was the best 3 of all the players so we knew it was going to be a dogfight. Game is .10/.25 nl, $15 buy in. We also decided that the winner had to show his hand even if he was not called, it was fun.

I am in the bb and UTG raises to 1.25 and we both call, I have K9c. UTG is a good player, extremely tricky and agressive and uses position to the max. He raises on the button almost every time, usually to a buck.

Anyway flop is AJ2 with 2 clubs. He bets 1.75, SB folds, I call, we both have about 16 bucks left. I have him on AK at this point. Turn is a 3 no club, I check he fires $3 and I call. Pot is $13.25.

River is a 10 no club. I check obviously, and he thinks for a few seconds and says, "Well, I think I have to go all in here" and does so for $13.

Final board - AJ23T
