BB is 35/14 over 40 hands. He has a $125 stack and I cover. I have not seen him get out of line yet, but we've only been playing like half an hour.

1. I raise AK from UTG, folds to BB who calls.
2. Flop [Th][2s], pot $8. BB leads $4, I reraise to $16, he thinks and calls.
3. Turn , pot $40, BB checks, I bet $28, BB insta-shoves all in for $88 more. Hero?

Yeah the CRAI looks horrible now, but I'm fairly confident if he has AJ/AQ he is not getting away (and 35/14's usually won't 3-town it oop) if I bet turn and river. I would have checked behind without much thought on the turn if I held AQ/AJ FWIW.

Are we calling this?

I dunno dood. When he calls your decent reraise on a dry flop I think I'm checking behind on the turn and calling a normal size river bet, and I'm not saying this in hindsight because he CR'd you.
