no HH. 50 NL. Table has recently gone down to HU. Was a fairly weak/passive table, and me and opp have been somewhat aggro because of it, with only a few hands against each other. he has thrown a CR on me when I cbet with missed overs. I have about $65, opp covers.

This is only the second hand of the HU.

I am the button/SB and get dealt :Ac::Kc: and raise to 1.75 (bet pot button, I am lazy) which has been my standard raise at this table. Opp thinks for a bit then calls.

Flop: :Js::Ah::Ad: (pot = 3.50)
opp checks, I bet 2.25 fully expecting a check-raise here. opp thinks, then calls. I am somewhat disappointed.

Turn: :Ks: pot = 8
opp checks again. I bet 6, again half expecting a check raise, opp calls again after a pause.

River: inconsequential low card, non spade pot = 20
opp checks, I bet the pot, opp thinks for a bit and calls.

shows down A9.

I feel as though I should have stacked him on this hand since it was headsup and he hit trip aces. The only place that I can really see playing it differently is the turn. If I check behind on the turn I feel as though he will be more likely to lead the river, and this will allow me to make a larger final raise if he does. but, by checking behind it also costs me the chance to juice the pot a little more with the nut hand, which makes for a smaller river bet.

I don't know if there was any way to get all of his chips, but I really wanted them on this hand and would like to know of some other ways to extract more in similar situations in the future.

Thanks.
