Split Pot From Runner Runner Flush

BAD BEAT

Even though we tied, I still consider this a bad beat. Pre-flop, I was an 85% favorite against just the one opponent. On the flop, I only went down to 80%, although there was a slight chance for a tie. The tie possibility increased on the turn, and we all know how it ended. I guess I can't blame this guy for going all-in with top pair on the flop, but I just can't understand why Lady Luck has to do me this way sometimes.
