1. Rxh7+ Kxh7
2. Qh3+ Kg7
3. Qg4+ Kh7 ( Kf7 4. Qg6#)
4. Qh5+ Kg7
5. Qg6+ Kh8
6. Rd3
whatever black does, Rh3 and checkmate will be coming
1. Rxh7+ Kxh7
2. Qh3+ Kg7
3. Qg4+
I.
3……..Kh8
4. Qh5+ Kg8
5. Qg6+ Kh8
6. Rd3 and mate follows.
II.
3………Kh7
4. Rd3 same as above
3………Kf7
4. Qg6#
(1)Rxh7+ Kxh7 (2)Qh3+ Kg7 (3)Qg4+ Kh8 (Kf6 4Qg6++) 4Qh5+ 5Qg6+ 6Rd3 wins
its mate with rxh7, a few checks and then the queen on g6, rd3-h3
1.Rh7+, then checking with the queen and side-stepping here to the g-file before bringing in the second rook. Looks decisive to me.
rxh7+ followed by qh3 qg4 qh5 qg6 and rd3. black cannot prevent rh3#
Rxh7 Kxh7 Qh3+ and then check on the white squares up to Qg6+ (If black moves Kf7 then Qg6#. same happens if Kh6.) Kh8 and Rd3 and mate with Rh3 is coming
The key move is 1.Rxh7+! … After Black takes the rook, the queen will check and zigzag until she is planted on the g6 square. After that is accomplished, white will play Rd3 with mate to follow….
1.Rxh7+ !, KxR
2.Qh3+, K any
3.Qg4+, K …
4.Qh5+, K…
5.Qg6… follwed by
6.Rd3 with mate to follow
Txh7 doesn’t work. It only leads to draw.
Qd2 then Qh6 +-
I forgot to mention in the line that I gave if Black plays Qb3 after Rd3, to attempt to sacrifice the queen, simply play Rd4 and continue with your plan of checkmating the king on the h file.
I think 1.Rxh7+ does work.After
1…Kxh7 (if Kg8 then Qg3+ goes back to the main line)
2.Qh3+…Kg7(or 8)
3.Qg4+…Kh7(or 8) (Kf7 4.Qg6 Mate)
4.Qh5+…Kg7(or 9)
5.Qg6+…Kh8
6.Rd3 mates
“Txh7 doesn’t work. It only leads to draw.”
Does it?
John’s already published second post (I think it is his second one) gives away the hardest thing to see. The rest is quite simple to calculate isn’t it?
1. Rxh7, Kxh7 (or Kg8 2. Qg3+, Kxh7 3. Qh3+ (Qh4+) transposing into the given line) 2. Qh3+, Kg7 3. Qg4+, Kh8 (the important thing to see is that Kf7 is not possible here due to Qg6#) 4. Qh5+!, Kg6 5. Qg6+, Kh8 6. Rd3 (looking as 1:0 but…), Qb3! (good try!) 7. Rd4!! +- and I see no way of defending h4. (Qd1+ 8. Bxd1 +-)
Is this right or did I oversee anything?
Best wishes
Jochen
John I think your earlier comment didn’t appear?
You probably mean
1. Rxh7+ Kxh7 2.Qh3+ Kg7 3. Qg4+ Kh7 (Kh6, 4.Qg6 mate) 4.Qh5+ Kg7 5.Qg6+ Kh8 6.Rd3 Qb3 7.Rd4
seems to be an easy win, have we overlooked something?
i’ll go with
Rxh7 Kxh7
Qh3 Kg8
Qg4
then, i don’t think black can escape because of the lock on the white squares:
… Kf7
Qh5 Kg8
Qg6 Kh8
then, Rd3 and black can do nothing about the coming mate on the h file
i think. too lazy to make sure. could someone check that?
1. Rxh7+ Kxh7 2. Qh3+ Kg7 3. Qh5 Rh8 4. Qg6+ Kf8 5. Bh5 Rxh5 6. Qxh5 Nb4 7. Rf1 a3 8. Rf3 Qb5 9. Rg3 N8c6 10. Qh8+ Kf7 11. Rg7# 1-0
1. R:h7+ K:h7
2. Qh3+ Kg7
3. Qg4+ Kh6
4. Rd3 Qb3
5. Rd4 —
6. Qh4+ Kg7
7. Rg4+ Kf7
8. Qh5 mate
Earlier flight to f7 with the K loses to Qh5# as noted by others.
Keeping the K back to h7/h8 is no better than this either, the rook lift is decisive with no mating threats and the idea of a further lift to the 4th rank if needed.
I am not sure why someone posted that this is only a draw – Qb3 for black only prolongs the game. Even a subsequent Qd1+ to try to lure the white R back to the first rank doesn’t work since the white B also covers d1.
Duh 3. …Kh6 gets mated by Qg6. So the important thing is to force the black K back to h8 and then lift the rook.
