5/10 NL Commerce. Game was pretty good but has gotten a little slow in the last hour and several players are playing kind of snug. I'm on the tail end of my session with a good image up about $1200ish. I have $3600 to start the hand.
Tight villain that I've never played with before opens $45 UTG with about an $1800 stack. I'm in UTG2/MP1 and elect to flat with QQ. This wasn't really the type of table I was expecting for it to go multiway and villain has a pretty strong range here (IMO) opening UTG to 4.5x. It ends up going 5 ways to the flop.
Flop ($225) QT5ss, checks to me and I bet $160. It folds to the SB who if you're familiar with some of Bart's hands is Mr. Song. He's usually a tightish passive middle-aged Korean. He makes it $500, and covers us, everyone folds and it's back to me. What do I do here?
