I have Aks and raise after very weak limper, I get 3bet by a slightly agro TAG in SB 20/13/2.12 weak limper calls and I cap.

Flop comes AQ9 2 suited none of mine. TAG bets we both call.

Turn comes an Ace TAG bets we both call. (I probably should have raised here).

River comes J TAG checks weak limper checks I bet TAG checkraises??? I fold.

My thinking is that he surely knows that I have either KK or AK? right and that I probably wouldnt fold AK but if I had KK its unlikely that he'd have a hand that doesnt beat me here.

He also knows that I'd value bet these hands.

Argh what do you guys think?
