Re: Bad flop play?
 

I check behind on the flop.

there are no draws you really have to protect against and I want some value against KK-JJ, at the same time, I don't want to create a huge pot with top pair crap kicker.

Against this many players you're not really looking to hit top pair here. Check/fold the flop... or check/call a smallish size bet.

Given the way you played it, I think I would've folded to the mini-raise on the flop. I'm smelling a set here and your top pair is no good.

You got lucky to hit the flush, but all in all I believe the way you played this is a losing play.
