... Get all the chips in on the turn holding the nut straight only to be beaten on the river card by the nut flush *and* a straight flush.

In case anyone's wondering about the PF call, this is OnGame where you earn points only where you contribute to the pot. I limp a fair few hands based on point value alone, and continue only when I hit the flop fairly hard. Top pair plus OESD was hard enough for me. Turn is perfect, so I shove as I must knowing full well that a club will kill me. I could have folded those last couple of dollars comfortably knowing I was lost.
All was not doom and gloom however, as I managed to turn $10 into $70 on a $25 PLO table and stay alive on another. All up, not a bad little session.
Note that the winner hit a two outer to scoop the pot!
