On the river I figure the guy that cold calls has the K high flush but as soon as the guy raises I begin wondering if I'm beat. As I think about it more it makes sense for him to check the river there seeing as he knows one of us has the ace high flush to pay him off. Do you think it was right to laydown here?

[autobet]

Looks like you made a good laydown with two ways to make a straight flush. You had the A so he couldn't be making the lone Ace play. He was also raising two players...

Why make a MIN raise if you are folding to a reraise, to make $2 more dollars? A full raise is not horrible on your part, if you are playing against players who cannot lay down a flush.

[Marnixvdb]

He may have had the SF, but 100bb stacks are usually not enough to find out with certainty.

The pot should have been bigger on the river already. Bet the turn harder.
