How did I do here? This was a very strange hand.

This was Opp's 3rd hand on the table. Pre and flop are standard, but the opp's weak raise on the flop is strange.

What do you do on the turn? Lead out? check/call?

once the turn c/r was flat called, I figured that I had the best hand (most players with a set would push here)...
