After a trip to the kitchen for snacks, and giving it a little more thought I would like to add that it is extremely rare for me to go on tilt. The example I described earlier being one of the exeptions. In fact, I don't tilt in tournaments, only in cash games where I can't believe people are playing the way they are with real money
. It's like they've hacked someone elses account or must be using a stolen credit card or something.
As far as tournaments go, I'm not sure how to deal with being on tilt, but the way I keep from going on tilt is to never risk too much of my chipstack on any one hand. Then it's easy to shake it off when you lose a pot. I also avoid pre-flop shoves, even with monster hands like As and Ks. Of course, you're not going to lay those hands down when someone else shoves on you. You just have to be aware that every chip you put in the middle is at risk. I often remind myself of what Superchicken always told his sideckick, "You knew the job was dangerous when you took it, Fred".
