I call the flop with the intention of folding if I dont hit my flush... on the turn sicne the guy in the middle call I rigured I barely had odds to call so I gambled... On the river my flush hits of course I push all in to take the poor sucker for anything he got left.... he calls...and we flip our cards... the chips go towards him! there's no straight flush!?? How can this be? I have the nut flush!!!... oh SHIT***#%@@#! its a Spade and a CLUB! I have Ace high!!! LoL
