hand 1: stats for villain? I call and re-evaluate turn. If hes a decent reg then i probably fold to any substantial turn bet.

hand 2: yeah, thats a set.

hand 3: thats the right play, just unfortunate sabre called. Irish's (most likely) dead money does provide a nice overlay from a pure odds perspective though.

hand 4: so what do you think he is calling your 3-bet with hear? KJ? QJ? How has he played in other 3-bet pots?
You need to bet this flop 100% of the time here with only 2 realistic hands that are beating you, and one of them (JJ) is incredibly unlikely. an aggressive villain is betting this turn w/ QQ every time after the flop checks through and may even bet out AK. I think your best line here is 3/4 pot the flop and get your money in on the turn. If he shows up w/ AA or god forbid JJ, then nh and reload.
