Thanks, I posted without showing that I did call, because I was interested to see if everyone wanted to raise flop (and hated a call) because of board texture and multiway. I'm not surprised you think a raise is better, but I am a bit surprised you don't hate the call.
As played:
Flop: ($0.95) T5
9
(3 players)
BB checks, MP bets $0.54, Hero calls $0.54, BB raises to $1.80, MP folds
What now?
