I was recently in a 90 person tourney, at a buy in of $5.50. This isn't my regular buy in, I prefer to buy in for less but I have been losing a lot and felt good that I could make a run at the prize money, so went for it.
Before I continue, I have been running bad for about a month or 2 so this hand is nothing special. Second, this is NOT a bad beat story, I just want your opinion if this play and another later in the tournament was correct.

Ok, I have been tight in my starting hand selection, however, I have only shown down 2 hands. The first was at a showdown and I had the nut straight on the flop and bet every street, the second was 1 hand ago and showed a bluff to my opponent. I was on the dealerbutton. The flop came 3 hearts with the ace and I had raised and been called by the small blind. I raise half the pot on the flop and they fold. I show 2 6 of spades and had no pair.
Next hand I pick up 2 black aces and see the following:
1 seat is sitting out and folds,
2 seat limps for 300 (blinds 150 and 300)
3 seat is sitting out and folds,
4 seat folds,
5 seat limps for 300,
6 seat limps for 300,
7 seat is sitting out and folds,
8 seat (me) in the small blind decides to play this very aggressive and knows that both seat 2 and seat 6 have been limping light in a lot of pots.
I go all in.
9 seat folds.

Stack sizes.
2 seat - 4,829
5 seat - 8,740
6 seat - 4,850
8 seat - 8,256

I go all in, get called by seat 6 who has 8 7 diamonds.
The flop comes 6 7 K all clubs.
The turn comes 5 hearts,
The river comes 7 spades
The 10,600 pot is shipped to my opponent.

My stack now 3,406.
Should I have played this another way to allow him to fold or was this just unlucky?
(Didn't reach the money as beaten on the river by J 9 off, holding 10 7 spades on a board, 10 8 4, (d) (s) (s) 2 (c) 7(h)

let me guess tilt? suck outs there happen all the time and usually the river card carries off the high hand all the time. I lose with KK and AA something like 80 percent of the time on there. Just crap you have to deal with.
