I don't like it. I just don't see someone bluffing at this pot, though they do.

And I don't like a raise to t300. Again, getting raised all-in would suck, and it would happen. I think you could get him to laydown by raising to t250 often, which I still wouldn't do. I think I just fold.

In this spot, I'm almost 90 percent sure he's bluffing b/c of the 2 diamonds on the board. Everyone checked to him on the flop, and he...checks???

If he had top pair on the flop, why wouldn't he bet out the flush draws?
Does anyone play top pair like that?

55 or 44 possibly floped 2pr might be played this way. I do agree he is bluffing/semi bluffing a good % of the time.

[apd138]

er i missed that he was last to act I now think there is a very good chance he is bluffing and much less likely he floped a set.

I fold pf and on the turn. I don't like putting this many chips on the line this early in such a marginal situation.
