White to move. How should white proceed?
I remember this one, and I think this is the third time this has appeared. White needs to prepare to play Qxh6, and there is no time for Rh3 since black can play Rh8 followed by Kg7 (or even Qb6). So, white gains the tempo with
1. Bg6! Kg7
Nothing will hold. If fg6, white just plays Rg6 with an unstoppable threat of Qh6#. If Kg8/h8, white plays Qxh6 with an unstoppable mate. The rest is fairly easy:
2. Bh7
Of course, 2.Bf7 is going to lose as the black king escapes, but now he is forced to either allow Qxh6, or allow white the time to play Rh3 followed by Qxh6:
2. …..Kh7 (Kh8 3.Qh6 wins)
3. Rh3 and there is no way to prevent the coming mate.
1. Bxf7 – Rxf7
2. Rg6 – ….
so 3.Qxh6++
if 2. … – Rg7
3. Qxh6+ – Kg8
4. Qxg7++
I think there’s no way to escape.
B-g6, fxg6
Rxg6 threatening Q-h6mate
1. Bg6+ Kg7
(1. .. fxg6 2. Rxg6 a2 3. Qxh6#)
(1. .. Kg8 2. Qxh6 fxg6 3. Qxg6+ Kh8 4. Rh3#)
(1. .. Kh8 2. Qxh6+ Kg8 3. Qh7#)
2. Bh7+ !! This clearance move was the hard one to foresee. Kxh7
(2. .. Kh8 3. Qxh6)
3. Rh3 a2
(3. .. Rfe8 4. Qxh6+ Kg8 5. Qh8#)
(3. .. h5 4. Rxh5+ Kg8 5. Qh6 Qxc3 6. Qh7#)
4. Qxh6+ Kg8 5. Qh7#
1. Bg6+! Kg7!
( 1…… fxg6
2. Rxg6 –
3. Qxh6# )
2. Bh7+! Kxh7
3. Rh3
1-0
1. Bg6+ fxg6
2. Rxg6 +- (threatening Qxh6#)
1. … Kg7
2. Bh7+ Kxh7
3. Rh3 +- (threatening Qxh6+ and Qh8#)
1. … Kg7
2. Bh7+ Kh8
3. Qxh6 +- (threatening Qg7# and Bg8#)
This is a repeat problem
1.Bg6+ Kg7
(1…fxg6 2.Rxg6 Be3 3.Qxe3 Rxc3 4.Qxh6#)
(1…Kh8 2.Qxh6+ Kg8 3.Qh7#)
(1…Kg8 2.Qxh6 fxg6 3.Qxg6+ Kh8 4.Rh3#)
2.Bh7+ Kxh7
(2…Kh8 3.Qxh6 Rg8
(3…a2 4.Bg6+ Kg8 5.Bh5#)
4.Bg6#)
3.Rh3 Be3
(3…Rh8 4.Qxh6+ Kg8 5.Rg3#)
4.Qxe3 Kg8 5.Qxh6 Qa4 6.Qh8#
