That one stupid mistake

[Big Pink Monkey]

About once or twice in a session, I make one or two big mistakes that cost me money. In cash games, it's not as big a concern because I'm usually able to use it to cash in later. People assume that any big move is just another crazy, stupid play. But in tourneys, obviously, it kills me.

I was just playing in the Sunday Warmup and I was way ahead of average as we were hurtling towards the money. I made a play that was so dumb on so many levels that I'm too embarrassed to even post it. One of those where I know I'm beat, but I'm just pushing all my chips in anyway in a random show of aggression. gg.

How do you keep yourself away from this?
