Just a quick update. The beat was even more heartbreaking, due to the following:
The flop was a rainbow with one heart, one diamond, one spade.
The turn was a heart. It is then that Luke Patten says "Ahh... split pot" and I stupidly say "no, a heart will give you the flush".
Lo and behold, the heart hits the river
Sick.
Still, if you can't stand the bad beats in poker then don't play the game.
