I'm not sure about the turn check. UTG's check kind of surprised me and I figured he was either going to check/fold or check raise me all in with a made flush. I figured by checking behind I'll still lose to the flush but possibly get some more value out of KQ or AQ type hand. What do you think? Played well or missed value?
