[MAF]

The ones that immediately come to mind are these (from memory). Sorry for not having full HH, but my PT needs fixing.

Favourite Hand won:
Stars Moneymaker Millionaire 1st round. >7000 runners, Top 50 go through to R2. About 59 left and first hand after break I'm dealt 72o in SB. I'm desperately short and need to double up (I'm around 56th or so).
BB has been sitting out since start of break. As it's fold to me I push. He suddenly wakes up and calls with A6. I spike a 2 and double up. I eventually qualify to the next round.

Worse Hand Lost
Paradise Million Freeroll a couple of years ago.
I'm short again and we're still early in the tourney. I'm in BB with K3. All fold to button who calls, SB folds and I check.
Flop AKx. (Can't remember the betting).
Turn K. I push.

Button calls with 99. I'm sure others have seen worse, but I honestly believe this is one of the worse calls I've ever seen.

River 9.

May seem insignificant to most, but this one always seems to stick in my mind.

I'm enjoying this thread. Keep them coming!
