There's a humourous angle to this that I'm sure others will pick up upon - whether they can resist stereotypes will be another thing
...but you know, a little alcohol can relax, and I think at club level might help tenseness...
I recall being beat by a player who regular drunk at a lot and at got through four pints of Guiness in our game.
I heard another story a few years back about a high level player in the civil service championship who was a known drinker and got intoxicated, created some nuisance, got little sleep and won the title !
I've only ever got two first places in chess tournaments. The last was when I got speaking two strange women in my then local pub and went with them to night club in the city, I got to bed after a few jars at about 3am and went on to win my section later in the day with an early start....
I can't recommend heavy regular drinking....but a tipple or two now and again is not necessarily a bad thing !
I find chess kind of boring when I'm sober (I'm maybe a little bit too stupid for this game) but when I'm drunk it's all I want to do, even if I suck. At the same time, I actually play a little better drunk because I gain a lot of confidence and motivation that I don't have sober. Anyone else experience anything similar?
