Yeah don't beat yourself up about that one. The only thing i thought was a *bit* weak was your flop re-raise...

first raises to $3.50
second calls.
i raise to $7

I think with the pot at ab out $15 here (your PFR x 4 callers + Unknown Blinds), the $3.50 (1/5 pot) raise looks like a weak probe, but the re-raise isn't enough to persuare anyone that you actually have the best hand.

The flush draw stayed in for implied odds with 4 players representing a hand and made it. Shoulda taken control and denied them the chance with a pot-sized re-raise.

Although i appreciate that a certain percentage of the time you will get nailed by a concealed set........ :S

But with hindsight you're saying "should i have folded to a strong re-raise by someone on a straight draw, when i had top 2 pair?"
