The solution to last Monday’s problem is that White wins with 1.Nb8+ Kc8 2. Re8+ Kb7 3. Bc6+ Kb6 4 Qe3+ ! Ka5 5. b4+
The saying ‘Think ten times, play once’ is attributed to Franz Liszt. The idea is that before you play a piece of music, you should think about what you are trying to achieve. If you don’t know what you are supposed to be getting from the music, how can you play good music?
This saying also applies in chess.
In this week’s problem, many players would not even think once. They would just automatically castle.
But what is White trying to achieve in the position? If you think once, or perhaps twice, you might avoid making an automatic move with White, and instead make the move that Kramnik thought of.
