Since you have the
, he can't have the nut flush draw.
if he's raising and then calling that hefty of a reraise with a hand like 89s, then fine, he can have my stack here. also, if he's one of the trickier guys at 2/4 who'll open with 55 or 22 (or i guess even 88 here), then fine, he can stack me.
That being said, i want as many chips in this pot as possible. i feel fairly certain that aces are good here. which i think you do, hence your question of 'how can i extract the most?"
If you check, it gives him a good chance to bet the river with a hand like JJ, thinking it might be good. he'll probably bet $100, at which point i think that's the last of the chips you can get from him, since any halfway decent player will fold JJ to any raise there.
That being said, i think this choice is even better. Bet $125 on the turn. i think he has two outs, probably on a decent sized pair, TT, JJ, maybe QQ. i can't imagine he's holding KK against a maniac here. 99's do-able too since this is 6 max.
Anyhow, i'm betting $125 and pushing against a raise. i just don't believe he has the 8. if he smooth calls and checks the river, i'm flat pushing.
