Villain is a bit loose pre but not crazily so - looser than optimal but not a huge fish. May overvalue hands post, but we've only been playing together for an hour so I don't have much of a read.
Straddle to my left, 1 limper to me in MP, I go $55 with A
J
, straddle (villain) calls, limper folds.
Flop: J
9
4
($115)
I bet $100, he raises to $300, I.... (he has $550 behind, I cover)
If I go all in, I think he can probably fold most hands I beat if he was getting odd with KJ or something. He'll call when he has equity to do so. He should have 2 two pair combos, 9 set combos, 4 combo draws, then like 11-12 flush draws and 8 OESD, possible 15 combos of KQ w/o FD.
