Villian is a young online pro...so hes good/aggression. Its 4-handed right now and ive been raising a lot of hands the past few rounds without much play back. Besides that he views me as another solid online player. I have like 2400 and he covers.

I raise to 40 with first to act. Villian reraises OTB to like 145. I call.

Flop is ....I check he bets 225 pretty quickly....i call.

Turn - ....I check he thinks for about 30 seconds and bets 600....i call.

River - ....I check he puts 3 $500 chips in the pot rather quickly to put me all in. I have $1400+ left.

Call or fold?

That's a pretty sick spot there, I can't see you being ahead on the river, which means you wern't ahead on the flop, there is such a huge range of hands that he could have that have a K in them, and have you beat here. A laydown on the river is what i would do.

On the flop lead out for 200 or so, checking you gave him a chance to play his TT/JJ like he had AK, The only hands you beat in this situation are 99-JJ or QJs, but i doubt he makes the turn and river bets without a K here.
