I would like this puzzle better without the a2 pawn. Ne8 threatening Rf8+ and mate Rxe8 Rxe8 Qxe8 Qxe8 and mate to follow. But the a2 pawn would allow the f1 rook to be pinned.
Then we’re forced to play the more boring forced dance Nf7+ Kg8 Nxh6+ Kh8 Nf7+ Kg8 Ng5 double threat of checkmate and game. But this is all forced. I like the eighth rank knight blocks better.
1. Nf7+ Kg8
2. Nxh6+ Kh8
3. Ng5 (Rxh2+ 4. Kxh2 Qd6+
5. Kg1)
1-0
Nf7+
Nxh6+
Nf7+
Nf5
Now, if Black plays Qxe4, then White checkmates by playing Rd8+
1. Nf7+ Kg8
2. Nh6+ (to get rid of the h6 pawn)
2. … Kh8
3. Nf7+ Kg8
4. Ng5 (threatens mate on h7, if the Rook moves Qg7 is mate)
4. … Qe4x (protects h7 and looks for g2, but unfortunatly
5. Re8+ Re8x
6. Qe8x and mate next move
Because of the black pawn on a2, white wins!
1.Nf7+ Kg8
2.Nxh6+ Kh8
3. Nf7+ Kg8
4.Ng5
Black has no defense against mate by Qxh7 or Qxg7.
How about
1.Nf7+ Kg8
2.Nxh6+ Kh8 (Rxh6 3.Qxg7#)
3.Nf7+ Kg8
4.Ng5!!
Now whte is threatening mate on h7 with 5.Qxh7#. IF black moves the rook along the h-file, white mates with Qxg7. I don;t see a proper defence for black.
1. Ne8 Qxe4 2. Rf8+ Bxf8 3. Rxh7# *
Definitely Nf7- almost without having to think much about it. The idea is to bring the knight to g5 via h6, f7 again, and then g5 to attack the hopeless rook at h7:
1. Nf7 Kg8
2. Nh6 Kh8 (Rh6 3.Qg7#)
3. Nf7 Kg8
4. Ng5
And there is no real way to prevent mate. Black can delay things with moves like Rh2 combined with Qd6, or by taking with the queen at e4, but delay is all he gets:
4. …..Rh2
5. Kh2
A mess ensues if white plays Kg1 because black takes at g2 with check. Continuing:
5. …..Qd6
6. Kh1 Qh2 (else Qh7/g7#)
7. Kh2 with mate on the next move by white.
Or, at move 4:
4. …..Qe4
5. Re8 Re8
6. Qe8 Bf8
7. Qf8#
Ne8
Four knight moves:
1.Nf7, Kg8
2.Nh6, Kh8
3.Nf7, Kg8
4.Ng5
After Ne8 what does White do after a1/Q ?
mate will be forced with a nice knight maneuver:
1. Nf7+ Kg8
2. Nxh6+ Kh8 (RxN->QxB#, BxN->QxR#)
3. Nf7+ Kg8
4. Ng5 any
5. Qxg7/xh7#
greets, jan
Try this
1. Nf7+ Kg8
2. Nxh6+ Kh8 (if Rxh7, Qxg7 mate)
3. Nf7+ Kg8
4. Ng5
threatening mate on h7 & the rook
cannot move because of mate on
g7
Now if only Black’s h-pawn were off the board, we could play Nf7+ followed by Ng5, eyeing the mate with Qh7#.
So….. we can do that anyway…..
1. Nf7+ Kg8
2. Nxh6+ Kh8
3. Nf7+ Kg8
4. Ng5
Now, Black is reduced to desperation checks, which only postpone the mate with Qh7#:
4. … Rxh2+ (ours but to do or die, not to know the reason why)
5. Kxh2 Qd6+ (ditto)
6. Kg1 Qh2+ (all right, already, sister)
7. Kxh2
If Black really doesn’t want to get mated by Qh7#, he can play
7. … Bxe4 (this is getting really silly), and get mated by 8. Qxg7#.
After 1.Ne8! a1Q 2.Q:h7+!K:h7 3.R:g7+ Kh8 4.Rf8# Nice!
Susan,im very sorry for my comment,it was a mistake !My fould,sorry!Please dont publish!
With respect,
Nicolau Ovidiu
1.Nf7+ Kg8
2.Nxh6+ Kh8
3.Nf7+ Kg8
4.Ng5 Qxe4
5.Rd8+ mates
Nothing wrong with it. Don’t worry Nicolau.
1. Nf7+ Kg8 2. Nxh6+ Kh8 3. Nf7+ Kg8 4. Ng5 Qxe4 5. Re8+ Rxe8 6. Qxe8 Bf8 7. Qxf8+ mate
1. Nf7+ Kg8 2. Nxh6+ Rxh6 3. Qxf7#
Anonymous at 4:27 is right. The new Q at a1 freezes the Rook.
It’s easy to get a perpetual in this position.
1. Nf7+ Kg8 (forced)
2. Nxh6+ Kh8
3. Nf7+ perpetual
if 2. … BxN , 3. QxR#
if 2. … RxN , 3. QxB#
Eh, what a bad pawn… Piece-size matters!
