Great hand to post btw, I wanted to do the math on this one:

your stack = 1,164,000

dead money after UTG fold (antes, blinds, and UTG raise) = 243,750

villian effective stack = 1,164,000

total pot after villian calls = 2,571,750

So, you are risking 1.16 million to win 2.57 million

1,164,000 / 2,571,750 = 45%

This tells us that you are contributing 45% of the pot.  I ran AQo vs JJ in pokerstove and you are 43-44% to win (the difference in percentage depends if he has the same suit as you or two different suits).

Conclusion:

For this hand, in this situation, you had to contribute 45% of the pot, but you were at best 44% to win.  Very close!  For this exact scenario, I think it's a fold.  But this is Monday morning quarterback after sitting here analyzing with a calculator.

If I were you and I was in this hand, I would have done the exact same thing.  I see a fish open UTG, then an aggro raise, I'm shoving AQ.  I think he would 3bet with a lot less than AQ, and the only hands you hate to see are AA, KK, QQ and AK.  Everything else you can deal with.  Look at it this way.  You put yourself in contention to make a final table with a healthy chip stack of over 2.5 million in a tournament of 4,231 people.  And you would have crippled the aggro player at the table.  You just lost a coin flip, that's all.  It landed tails when you needed heads.  That's it.  You finished in the top .3%!  That's quite an accomplishment!  You should be proud.

GG Sen.

P.S.  How did you know that the UTG player was a losing player and he had played over 1000 mtts?  I only play on Bovada with anonymous players, so I don't think I can look it up.  But if I ever go to other sites maybe I can use whatever program you used.

Given the positions at the table I would fold as their combined ranges, on average, are going to be dominating us a lot and we are going to lose a significant portion of our stack in a pretty marginal situation.
