25NL Playing 53; don't worry it is sooted!

[bored]

BB is very passive. A few hands ago he open limped QQ; minraised on an 855 flop, bet the turn weak and checked behind a river A.

BTN is 50/15/2. Haven't seen him 3bet yet; he usually bets the flop small and check/calls down marginal hands. (He had K8 vs the other guy in the 855 hand, which he called down with).

I almost never complete this pf, but this time I think it is okay with all these people in the pot.

Flop is good for me, BB's raise doesn't scare me at all; I put him on a 9 or maybe another overpair. I'm not sure what BTN's huge raise looks like though. Would 99 play this way? A3? A pocket pair? A flush draw? 9x?

What is our plan for the hand here?

Maybe I should have just folded pf [img]/images/graemlins/grin.gif[/img]
