AcTh vs. 5h5d2h
 

Just had joined this table. After the flop the SB took quite a long time to act. At this point I'm 70% certain he doesn't have a 5. I believe he either has a flush draw, over cards such as AK, AQ, or something like A2 or maybe K2, etc. On the turn I'm a bit more certain this guy has A2. But, not enough to bet into it if I'm wrong. Should I be betting here?

What's your move here?

I'll post the results later, if you like.

Re: AcTh vs. 5h5d2h
 

Against specifically A2, raising the turn won't gain you much unless SB will then pay off the raise and a river bet unimproved (which he might, actually). Against a hand like K2, a turn raise starts looking better, I think, especially if there's some chance of getting SB to lay it down on the turn. Also, if SB is semi-bluffing a flush draw or a straight draw, then raising now could gain an extra bet those times the draw doesn't hit, if SB would give up on the river after missing instead of firing again on a bluff.

Anyway, if I did raise the turn, I would probably fold to a 3-bet. Calling down instead seems all right to me, though. (Edit: I mean calling down instead of raising in the first place seems all right to me. I don't think I like calling down after getting 3-bet, so much.)

Personally, I wouldn't make too much of SB's pause on the flop, which could mean a lot of things. Possibly, for instance, he's simultaneously doing something else while playing and isn't giving the table his full attention. Also, he could be deciding how much he likes his 66 (for instance) or whether he wants to lead with his trip 5's or slowplay them.
