I haven't won a SnG jackpot *yet*, but I'm hoping to keep my current streak going. I just started playing the Dirty Dozen jackpot SnG's this morning and as of right now I have respectively finished 7th (BAAAD beat), 2nd, 1st, and 1st. So... 2 more and I win the $2,000 jackpot. Even if I don't win so far I've made $30 off of $9.60.
The last one I was in my nerves were almost shot amongst the final three. Once the final three hit, we NEVER played the flop. It was all-in one after another... stealing blinds and hoping to knock someone out. At one point I was shortstacked with 670 chips with blinds at 200/400... but I got uber lucky with the cards and finally won it with AA vs J9s.
