Bodog 8/16 LHE (6-handed)

Cobalt is MP w/ A 7 . CO is quite loose (likes to cold-call w/ any two suited) and slightly tricky at times. SB is an overaggressive monkey with a VPIP of ~98%. He does show some post-flop restraint, but he's still prone to bluff on later streets when shown weakness. BB is mostly a calling station, but he does sometimes bluff and bet draws. I've been playing TAG.

Pre-flop:
1 fold, Cobalt raises, CO calls, 1 fold, SB calls, BB calls

Flop (8 SB): 2 3 4 (4 players)
SB checks, BB bets, Cobalt calls, CO calls, SB raises, BB calls, Cobalt 3-bets, 1 fold, SB caps, 1 fold

Turn (9.5 BB): 8 (2 players)
SB checks, Cobalt checks

River (9.5 BB): A (2 players)
SB bets, Cobalt calls

Final Pot: 11.5 BB

I would just raise the flop when it first came to me to because I would like to see pretty much everything fold behind me except of course a smaller flush draw and he would cold call anyways. If we can get any pair or overcard to fold we may win this pot unimproved given your read on sb and if we can get a 6 or a A to fold we would win the whole pot if a 5 came. The pot is big enough for me to take.

Also what is up with BB on flop.

Had the action messed up. SB checked the flop initially. BB bet it.

I like the flop - you want people in to get maximum value out of your draw. The river could go either way, but I don't have any problem with a call with the odds you're getting.
