Since it was a new table, I had no read on UTG. His pre-flop play had me a bit confused. But I put him on A-Q. I figured AK, AA, KK, QQ, JJ would re-raise (no?).

His minimum bet on the flop screamed weak to me. I seriously doubt he would play a flopped set with min bet. So I think he missed on the flop. I put in a nice re-raise to find out.

His min re-raise told me he didn't have anything and was angry at my re-raise. That's why I pushed. I had top pair with an ok kicker and jack high flush draw.

Is my thinking flawed here? Is this not a tourney move? I'm used to cash games.
