Ha, I had the same problem today, was firing on all cylinders in a 10dollar buy-in tourney, 18 people left, i was about 5th or 6th, a higher stack raised pre-flop, so I thought i'd go all out with my pocket rockets.
I went all-in, he called me with A8.
8 on the flop, 8 on the river, he caught trips.
Suffice to say, I closed the poker straight away before I did some damage to my balance
