some thoughts on this, as we all have experienced moods and how to play.......
when in a crap mood, you have to be careful. If you play too impetuously, without thinking, things can go south fast -- especially against competition that is at least equal in Rating to you.
However if you are in such a mood and play someone several hundred Rating points below you, you might be able to take out your anger and frustration on them ! :>)
Apparent with faster time limits. If you play 14 days per move, it can be torture, when you move fast -- to try to blow them off the Board and they move slowly, trying to take advantage of your quick moves.
Sometimes I notice I play better when I'm not in a great mood even worked up about stuff, but not to the point of distraction, although I prefer the times I play well when I'm simply relaxed, focused and energetic.
