so, this guy is stealing blind 75% of times and I have AK on the button. And he is raising. So I reraise him 3 times his raise. And then he 4bets me. Was it correct to 5bets him?

Is this a cooler or should I only have called his raise and that's it? I wanted to punish him for stealing.

You lost a Flip, nothing to discuss. The fact that he had 7s means he could of had many hands you are flipping with.

Was it better to call the reraise and see a flop? I don't like coin flips when he could have had AA or KK as well (so no coin flip there).

That really depends on if you think he can call with AQ or any other none pair hands.

Seems fine, although just jam the 5bet. Villain played his hand worse than you played yours.

In NL2 it seems to me any time someone 4bet he has AA or KK, rarely QQ. Wouldn't that be risky?

I agree you probably should have jammed the 5bet.

Giving him a tight range of AA-77, AKo, AKs, you still have a stronger range if you are not jamming 99-77. If you do jam, you most likely have a range like AA-TT, AKo, AKs (you can even throw in AQs) and you are ahead of his range.

I don't understand. I don't think I've ever seen anyone in NL2 4-betting unless they have QQ, KK or AA. Maybe against better players it would make sense jamming with AK, but it seems I would be behind there?
