I made it to third place. The hand that killed me was this one:
me: tc9c
Board: QcJcQd
My opponent goes all. I call. I've got him covered. He shows Qx.
Next card is J, and my straight and flush draws are now moot.
Cardplayer.com puts me at 42.1%. At the time I thought I was closer to 50%. Still, there was enough in the pot that I was getting correct odds to call.
