anyone else pushing on the flop? The queens probably aren't good at that point and although you've got a ton of outs I'd want to take down that pot as soon as possible. If you call you're not getting any fold equity on the turn and popping it up to $300-350 is still gonna tempt him in to see another card, he's only folding a bluff there IMO. Pushing the flop gives the best chance of getting him to fold with the safety net of plenty of outs if he calls and has you beat.

How had the sb been playing up until then?
