Challenge Progress - Not there yet!

Ok, so I haven't made it into the money yet on the freerolls on Absolute Poker, but last night I was oh so close. I was 12th in chips with about 28 people left (top 18 pay out). I had around 38,000 in chips. The hand I get knocked out on? Ok, I'm on the button. I get pocket aces. One of the chip leaders is to my right. Blinds are 1000/2000 ante: 150. Gets raised by someone in early position (2nd to act I believe). By the time it gets to me there are 4 players in the pot, including the person on my right. I move all in (knowing that I can probably get the original raiser to fold as he was just raising pots all night with practically nothing). Only person to worry about is the big stack. Everyone folds.....except the person to my right (the big stack, he had me covered by over 100,000). He flips his cards AK of hearts. So, ya know, I'm feeling pretty good about my chances here. Flop comes 8d,2c,Ks rainbow. Still feeling pretty good, little nervous though. Turn comes, Kc. Oh CRAP! I only have 1 out left in the deck (the other ace). Needless to say, it didn't come. River comes Q of diamonds. Can't blame the big stack for calling here. He told me that he actually put me on Queens or Jacks, and since he had me easily covered, he called. Don't blame him there, I'd probably do the same if I were in his position. So, I finished in 27th place out of 2000, out of the money again. But my best showing yet in the freerolls. The challenge continues.
