Hi All
Not posted on here before but have a hand that's bugging me. Any opinions would be appreciated. Here goes:
$5 rebuy - 860+ entrants - just into the money after 3hrs+ play - 160 players left - Blinds have just gone to 1000/2000 plus 100 ante - I have had above average/average chip stack all through tournament - I have only recently been moved to this table so have no knowledge of players - My stack is 67k and I'm in Small Blind. Big Blind has 70k.
My Hole Cards:

First seven players fold to me
I raise 4000 to 6000.
Big Blind calls
Flop:

I bet 10,000
Big Blind raises All-In
I have top pair of K's with Q kicker. I know nothing about my opponent's style. Does he put me on a steal and make a stand? If he's hit a monster why did he go All-In? FFS what's he got? I think long as possible, using my Time Bank (which is a rarity for me) and eventually decide that my hand is strong enough to call. I call for all my chips and he turns over AA which holds up through turn and river.
Usually when I lose a big hand I know whether I was unlucky or made a mistake but in this instance I simply cannot decide. Apart from taking on a stack that could knock me out I really dont know if my call was a mistake. I am torn between protecting my remaining 50k and the probability that my hand was in front post flop.
Your views please.
