Re: AK Question
 

Heh. Super strong play by opponent. Need reads to continue. I think he could very possibly have AQ/AJ but the majority of players will have you crushed, two pair or set. I guess 34 got there too but doubt this is much of his range.

Summary: IMO fold w/o read.

Re: AK Question
 

There's some chance Button is doing this because he's pissed about the checkraise, but I would fold here. I mean, he is saying that that ace doesn't scare him, and before that he did call the flop, and those two things together seem like bad news without a read that we have a reason to distrust Button.

Re: AK Question
 

I don't know if I like CR turn here. We are over 130BB deep, and CR doesn't leave us with too much to work with, if he 3bets AI, or shoves river or something. I dunno, I don't like going broke with just AK here, especially after he called flop.

I'd probably just fire again on turn, and fold to a raise. As played, I fold too.

Your CR size looks kinda small IMO.
