My main question is what is the best line after he three bets. Villian is 13/7.5 When he three bets preflop, I put him on a pair or AK also. I dont think I can just call OOP so, I decide to push thinking its probly a coin flip and even if hes got KK, I still have a decent shot at taking it down. Is this spew???

He actually 4-bets you: blind=1 bet, raise=2 bet, reraise=3 bet, rereraise=4 bet, and so on.

Yeah, once he sticks that in there you pretty well have to assume QQ+ against the average player, more likely KK+, so even if you hit you're screwed pretty often.

I just fold to the 4-bet against an unknown. He's making it pretty clear that he's ready to stick it all in.

fold once he comes over the top. You beat precisely nothing hes doing thsi with unless he has some big brass balls
