White to move and checkmate in 4.
2r1rk2/5pR1/2q2P1p/2n5/pp1p3B/3B3p/1P1Q2b1/1K6 w – – 0 1
1 Rh7 Qxf6
2 Bxf6 Re1+
3 Qxe1 Kg8
4 Rh8#
else
1 Rh7 Kg8
2 Rh8+ Kxh8
3 Qxh6+ Kg8
4 Qg7#
Rh7 Qxf6
Bxf6 Re1+
Qxe1 Nxd3
Rh8++
The winning move has to be some rook move, to threaten Qxh6+, followed by mate.
The two candidates that look promising are Rxg2 and Rh7. Both look pretty strong. For instance, black can’t recapture the rook: after 1 Rxg2 Qxg2, 2 Qxh6+ Kg8, 3 Bh7+ Kh8, 4 Bg6+ Kg8, 5 Qh7#.
But black can escape mate with 1 Rxg2 Re1+, 2 Bxe1 Qxf6, and while losing a piece, black has parried the mate threats.
So I suppose it has to be 1 Rh7. Black again has to respond 1…Re1 (…Kg7?? 2 Rh8+! followed by Qxh6), 2 Bxe1 Qxf6, covering both mate threats of Rh8 and Qxh6, and black survives.
That means white has to recapture with the queen, so that the bishop still protects the crucial f6 pawn:
1 Rh7 Re1+
2 Qxe1 and now black can’t stop the threat of Rh1#: if Qxf6, Bxf6 renews the same threats; and if Kg8, Qg3+ Kxh7, Qg7#. So that’s the answer!
1. Rh7
1.Rh7 !
If 1…..Qxf6 2.Bxf6 and now White will only need one move to mate: 2….Re1+ 3.Qxe1 and 4.Rh8 mate
If 1….Re1+ 2.Qxe1 Kg8 3. Qg3+ Kf8 4.Rh8 mate or 3….Kxh7 4.Qg7 mate
If 1….Kg8 2.Rh8+ Kxh8 3.Qxh6+ Kg8 4.Qg7 mate
1.Rg8+! Kxg8
2.Qxh6 Qxf6
3.Bxf6 …
4.Qg7#
1.Rh7+! Qxf6
2.Bxf6 Re1
3.Qxe1 Nxd3
4.Rh8
1. Bh7 + Re1
2. Qe1 + Qf6
3. Bf6 +….
4. Rg8
Why not qxh6?
it seems, the answer is:
1. Bh7 Qxf6
2. Bxf6 Re1+
3. Qxe1 any
4. Rg8#
greets, jan
That can’t be right.
1.Rg8+! Kxg8
2.Qxh6 Qxf6
3.Bxf6 Re1+ and you won’t mate next move…
1.Rg8+! Kxg8
2.Qxh6 Qxf6
3.Bxf6 Re1+ and you won’t mate next move…
CANNOT BE! WHY?
Look at this,
1.Rg8+! Kxg8
2.Qxh6 + Re1
3.Kc2 or Ka2…then you will face a very serious problem..
1. Rxh7+ then 2. Bc4+ Phil Innes
I should have written Rxf7 then Bc4 – Phil
