Taj part 2

Shortly after the dinner break my stacks about 90-100k, a younger kid got moved to our table with about 14k. He shoved allin on the button at 500 1000 100a when the bb was short also. I isolated in the sb w ATcc, he had 44 and I lost the race. A few hands later I double him up in a questionable play by me, with AQs aipf after he flats with KK.. so there goes half my chips. I then get up to about 90k again when I get dealt KK in MP. Same kid raises 3200 at 600-1200 from 1st or 2nd position and I make it 8800. He calls and I check behind on the Q72 feeling like he has mostly medium pairs here. Turn is a 5, rainbow board.. he bets 7500 which is rather small and I feel like I'm def. ahead of his TT/JJ. River is offsuit 3 and he bets 7500 again. At this point I don't really see a lot of value in raising as there's only a few hands he can have that can call a raise that I beat but I'm dead certain he has one of those hands as his river bet looks like such a blocker bet with AQ, maybeeee JJ. Anyways... I can't help myself and raise to 20k and he calls with AA (which for some reason didn't enter my mind here), so there goes half my chips again. Next orbit I get KK in same spot where the kid raises to 3100, I reraise to 8500 and he makes a raise for the rest of my chips, I call he has AA again and I'm out. Next live tournament should be Harrahs circuit in AC 2nd week of December.
