Good luck with today's puzzle:
This beautiful study illustrates a point of the greatest significance in the end-game, especially in King and Pawn endings - the importance of exact timing. White to play and win.
Here is the solution to yesterday's puzzle:
Tonoli - Vandenbroeck
Brussels, 1967
If Black were to play at once 1...Rg2+ Kh5 Rad2 intending Rd8-h8, White would play 3.Rd7 defeating the whole scheme, But Black can most ingeniously gain a tempo as follows: 1...Rd8! (threatening 2...Rg2+ 3.Kh5 Rh8+ 4.Bh7 Rxh7 mate), 2.Kg3 Against 2.h4 Black plays 2...gxh4 3.Rc7 Rg2+ 4.Kh3 Rg3+ 5.Kh2 (5.Kh3 Rg1 6.Rxc6+ Kg7 and White is helpless), 5...Rd2+ 6.Kh1 Rxf3 and wins without difficulty. 2...Rd1 (threatening Rg1 mate), 3.Kg4 Rg2+ 4.Kh5 Rd8 forcing mate, e.g. 5.Kh6 Rh8+ 6.Bh7 Rh2.
Not at all easy.
Not at all easy to type in either - must have taken half an hour to check all the variations.
