Learning from a short game
When a strong and experienced player meets with a weak opponent who has just started playing chess, the stronger player would expect a number of poor moves and mistakes from the beginner. On the other hand, mistakes and poor moves happen quite rare for experienced players. It could be good that the beginner studys the moves of better players and practice more. The following illustrative game was the result when a world chess champion met an anonymous amateur in a simultaneous exhibition given by the champion.
so beginners keep on training!
