White to move. How should White proceed?
1. Rh8 Kxh8 2. Qh1+ Kg8 3. Qh7+ Kf8 4. Qh8x
Is it not 5 seconds problem?
1.Rh8+ Kxh8
2.Qh1+ Nh5
3.Qxh5+ Kg7
4.Qh7+ Kf6
(4…. Kf8 5.Qh8#)
5.Qf7#
1.Rh8+!!.Kxh8.2.Qh1+!.Nh5.3.Qxh5+.Kg7/g8.4.Qh7+.Kf8.5.Qf7#!
In the above main variation the following are sub variations.
>A-2…Kg8.3.Qh7+.Kf7.4.Qh8#!
>B-3…Kg7.4.Qh7+.Kf6.5.Qg6#!
Mate in 5!!
1.Rh8+! Kxh8 2.Qh1+ Kg8 3.Qh7+ Kf8 4.Qh8 mate.
Rh8+,K×R;Qh1+,kg8;Qh7+,Kf8;Qh8+
1. Rh8+ Kh8
2. Qh1+ Kg8
3. Qh7+ Kf8
4. Qh8++
1. Rh8+ Kxh8 2. Qh1+ Nh5 (2. … Kg8 3. Qh7+ Kf8 4. Qh8#) 3. Qxh5+ Kg7/g8 4. Qg6+ Kf8 (4. … Kh8 5. Nf7#/Qh7#) 5. Qf7#
What else is there besides 1. Rh8+ K:h8 2. Qh1+. The threat is 3. Qh7+ and 4. Qh8#, so Black must play 2…Nh5, but 3. Q:h5+ and 4. Qg6+ mates on the next move whether Black flees to f8 or h8.
I got this one almost instantly:
1. Rh8! Kh8
2. Qh1
The point behind white’s first move- it allows the queen to infiltrate the black king’s position with checks- an important point given black’s own threats against white. Now black is toast:
2. ……Kg8 (Nh5 3.Qh5 Kg7/8 4.Qg6)
3. Qh7 Kf8
4. Qh8#
Rh8+ Kxh8
Qh1+ Nh5
Qxh5+ Kg7(or Kg8)
Qh7+ if Kf6
Qf7 Mate
if Kf8
Qh8 MATE
1. Rh8+ Kxh8
2. Qh1+ Kg8
3. Bh7+ Kh8 (if Kf8 then Qh8#)
4. Bg6+ Kg8
5. Qh7+ Kf8
6. Qh8#
