The other day I was in my first really big tournament..the 22K Sunday tournament at Carbon. I'd won a Rounder's Radio Winner Take All Tournament for $60 and a $60 Satellite coupon.

It was during this tournament that I realized how important it can be to "stay focused" in the face of criticizm from other players.
I started the tournament very focused on the task at hand. I was playing only premium hands, being patient, folding in the face of a tempting draw... I was pretty card dead for the first hour, but still had a little over 2/3 of my beginning stack when the first break started.
After break, I came back raring to go and decided to call for the heck of it with an A 3 off, blinds were 200/400. Yeah..not really a good hand to call, but it was right after break and I was hoping to get away with something in a fairly late position..lol Well, there were only 3 of us in the pot... me, the sb and the bb and the flop came up 2, A suited, A.
Now, in this hand, I was really just looking to pick up the blinds. I had trips on the flop, but my kicker was low and there was a straight and flush draw on the board. With only the blinds and myself in the pot, they could be holding anything since they just called before the flop... this was my logic anyway... lol
So, I bet twice the bb and they both folded. I got exactly what I wanted and was happy. Then... the bb said, "Why would you bet with trips on the flop?" Not really anything to throw anyone off their game, right...wrong.. his question broke my focus completely.

Everyone had been completely silent and in concentration mode until this guy piped up.
From then on, I was second guessing every hand I was in, wondering if I was doing the "right" thing. I'd totally lost my focus. None of the cards I was dealt seemed to be good enough to play. I ended up basically losing my stack to the blinds. My confidence level was so low, that I couldn't even pull off any type of semi-bluff with the mediocre cards I was getting. When I had about 3 times the bb, I got an A, T suited and pushed.. and was out in 44th place

This experience with "losing my focus" shows just how much the mental aspect of poker can interfere with how well I do in a tournament.
