Last night I played the same freeroll and I was eliminated holding a pair of kings and I had a healthy stack of about 20 big blinds at the time. Preflop action: I don't remember whether there were anyone limping in front of me or if it was just folded to me, but I was in middle position and I raised to four or five big blinds and it folded around to one of the blinds who raised all in. My opponent had me covered by about five or ten big blinds and something about his previous plays lead me to believe that he wasn't holding a pair of aces but he had a pair of kings or ace king at best or that he was just trying to use his or her big stack to bully the table to win more chips. I considered folding because I would still have a healthy stack of chips and he could of hit the flop with whatever he had. I called all in and it turned out I was right. He had ace queen offsuit and on the flop he paired his ace so I lost again.
I am not happy with this result because I could of folded and walked away with a healthy stack and I still would of been in the tournament, I still would of had a chance. Instead I got greedy.
