Villian is a pretty good TAG, and a regular at UB. Interestingly, I think he is a losing player in my database. He regularly 3 bets PF, and multi-tables, and imo is solid. He has $194 and I cover.

I'm dealt K[d] J[d] in MP and call a standard raise to $7 from villian UTG.

Folds around... heads up to the flop.

Flop ($17) K[c] 7[d] 7[h]

Villian CB's $12, as he does 80-90% of the time, just like I do. I just call. Thoughts?

Turn ($41) 4[c]

Villian thinks for about 8 seconds and bets $31. After almost laying it down, I just called again, after about 5 seconds or so.

River ($103) J[s]

Villian thinks for like 10 seconds and throws out a $75 bet. I've known him to 3 barrel before, and 2 barreling bluffs is definately within his capabilities which in heinsight is why I stayed in the hand up to this point I believe.

He has $69 left. What's my best action?

Against a TAG fold preflop, even against a sLAG who plays postion well fold preflop.

As palyed..
Flop call is ok, turn call is ok too, now call river as you can beat AK now.
