How stupid could i be?

I played the 1000$ Blackmoonpoker.com Freeroll on Betsonpoker.
Only 102 Player registert. You read right 102 Player, 1000$ Freeroll !!!!
Top 15 paid, 15th earn 20$. Im 6th under last 17.
AK in the BB. Blinds are 200/400, my chipstack about 10K.
1 call, I raise to 2000 he calls. Flop came AJ6. He bet 1200. I had the feeling he had AJ.
I call him, a 2 on River. We both check. 8 on the Turn. He set me allin.
From the first Moment i saw the Flop i had the feeling he had two pair.
So what am i doing? (Idiot like me)
I call, he had A 2 two pair and im out 17th.
AAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHH
I dreamed from this Hand i think.
So try to learn from that, so you dont make this mistake.

We have all been there and done the same thing.

The other week in the $3 Rush MTT I was 10 away from the money and picked up AK in early position. I raised 5 x BB and the chipleader who happened to be on my table called.

THe flop came over K 6 4. I bet, he re-raised. For some reason I went totally mad and shoved the lot in over the top. He called turning over 6 4 offsuit...

Yes 6 4 offsuit.... Out I go and that donk is sat there with a monster stack...

Always go with your instincts.
