A friend of mine sent me a hand that took place yesterday and I thought I would get some advice here. This hand took place in a $210 weekly multi table poker tournament. 8000 starting stack. 25min levels till 1st break (5 levels), 30 min levels after. Re-entry till the end of that break. Friend got there a bit late and missed the 1st level. So level 2 the blinds are 50/100. He just sat down and it was the 1st hand he was dealt. He is in the big blind. UTG and UTG+1 fold. UTG+2 raises to 400, also with an 8000 starting stack. Folds around to friend in BB and he looks down at AA. He re raises to 2000 and the UTG+2 calls. Flop KK6 rainbow. Friend checks and player shoves all in for 6000........What would you do and why?
