SB checks, I?
CO has been reasonably aggro. SB is more likely a giant fish who can't fold 98s than getting tricky with AA. I don't think Squeezing pre is bad here and is probably +EV, but please don't just post shove/fold preflop and add nothing else.
I can't bet/fold. Bet calling seems bad. If it checks through than I probably have the best hand, but will never have the best hand on the turn. I don't know if I am ahead of buttons betting range enough to c/c or crai, but I do think I have the best hand on this flop a ton.
