Losing Concentration

[Michael C.]

After playing my best game for most of the weekend, last night I felt rushed and irritated, and definitely made impatient plays I wouldn't have made under normal circumstances. I thought about it later and think that's one of the main things that separates a great player like Phil Ivy from a lot of players who for even 4-5 hours at a time can play very well. It's also an ocassional leak in my game I know I need to work on (I don't go on tilt since I've played SNG's, but I do sometimes play when I'm not really into it). I don't really know if there's an answer here other than to concentrate more, but I'm just wondering if any of you who constantly multi-table for hours on ends have any tricks to keep your mind in the game, and quickly recognize when it isn't.
