The solution to last Monday’s problem is that White can push Black over the edge by playing 1. Ra8. Then Black just has too many pins, pieces en prise and threats to cope with.
This week’s problem illustrates the importance of winning won positions. In the diagram, White is a piece up. he is winning, but needs to make sure his opponent wants to resign. His opponent won’t want to resign if he feels he can still conjure up something out of nothing.
If you prevent your opponent from having hopes of saving the game, he is more likely to resign.
How does White squash Black’s counterplay? White has to be careful. His bishop is attacked, the Black rook might come to e1 with a check, and possibly one day the passed Black c-pawn might become a nuisance.
White wants to prevent all of these bad things happening.
What should he play?
