I'm not sure what I could have done better here, but I'm sure I *could* have done better..

I should've known he didn't have a flush when he bet into me on the turn, I think, so I guess I should've raised him on the turn and put the doubt into HIS mind about it?

I think you lost the least on this pot. The best time to get him off this hand was on the river but I can't see myself making that bet either.

I agree with Brian.

Considering you were set over setted, you should be thankful that the flush was out there slowing everyone down.

You played it pretty well
