A8o vs CC and BB on Kxx flop

[sweetjazz]

I think the flop check is fine. It's pretty close, because button will sometimes be coldcalling with Axs and other suited hands (e.g. 87s, T6s) and hands like AJo and ATo.

BTW, given the rake structure of 3/6, I'm pretty sure open raising A8o in the HJ is a slightly losing preflop play. A9o in this spot is probably close to breakeven, and ATo is definitely playable.
