effective stacks are about $70, 50NL. opp is BB, I am SB. opp has been very LAG, lots of pf raises, lots of pot-sized c-bets. has not faced too much resistance at the table, although has been caught with air against the short stack a couple of times. I have played back at him periodically, although not too often as I am out of position.

1 limper from the CO, I limp the SB w/ . BB raises to 2.25 (psb)
CO calls, I call.

I limped half expecting a raise, and didn't mind when it came against this opp.

flop comes:

I pick up 2nd pair and an OESD, w/ a backdoor flush draw, and figure to be ahead, so I go for the CR expecting a ~PSB from opp, and this also lets me know if the shortstack in the CO is interested or not.
opp puts out his PSB ($6) and CO folds, I raise to $20, opp calls.
this leaves roughly 40 behind. and the pot at a little over 40

turn: :Jd:

I push.

what do you think?

I expect opp to fold pretty well everything but a set, or a str8 here, maybe call with an OESFD. J8 may call too, but a lower 2 pair would probably fold.
