Unforgivable Mistake

Paradise poker's 50 up game.

One bloke has been raising with shite all game and sits on 20,000 chips.
I have 11,000 chips and am waiting for one of his big raises when I have a hand.
I am watching TV while playing, this helps when you are wanting to play only the better hands I find.
Suddenly the villain raises to 3,000 (BB is 1000 I think).
I have JJ and raise all-in...he calls it and shows 66.
He wins the pot, and takes me out, by making trips.

Ah well...that's poker.

BUT...
I finished in 6th place, when 5th place carried an additional prize of a seat to a bigger $3000+ game at the start of next month.
This extra game is the main reason to play the 50 up series.
I didn't realise even that this was the final table...when I did realise I was gutted.
There were others on the table who had short stacks...
I had to fold...there was no other option.
This play was stupidity incarnate and I am utterly pi$$ed off that I messed up in this way.
