The issue of tiredness during games is one that’s well worth considering as it plays a major part in our games. The problem is that a player who is tired will naturally desire to save energy by not continuing to cudgel his or her brain. So it results in a diminishment of determination and sloppy moves are the result.
Is there a way to prevent this? Indeed there is but not via any quick fix solutions such as coffee. It’s simply a question of making sure you’ve had enough sleep before games and not overly taxing yourself.
This gives young and/or unemployed people a massive advantage over those who work for a living, volunteer to be captain/chauffeur for the team and then play in the evenings after work. Yet it’s amazing how many people put themselves through this and then get very surprised when something bad happens, like hanging a rook. They’re tired but kind of got used to playing chess in this state.
The cure is obvious but would lead to the wholesale devastation of what’s left of club chess; is there a better solution? Indeed there is, and that’s to exhaust those who go to matches with fresh untaxed brains. And the best way to do that is to convince them that what they really need to do is study 20 moves of Dragon theory just before the game as otherwise they’ll be at a horrible disadvantage.
Really, this works a treat. But you’re only likely to pull this off on those you’re in contact with such as your unemployed team mates…
