On a [2s][As][6s] flop, Joe Keuther check-called a bet from Ryan D'Angelo. On the [Js] turn, the action was the same. When the [4s] hit the river and put a flush on board, Joe checked for a third time and Ryan bet. After a brief tank, Joe made the call and was shown the bad news: Ryan held [Ks][Kh] for the nut flush, and he will take down that pot.
