Na6/Kc8/Ne6/Nc7+
Na6
Kc8
Ne6
Nc7
NxBc7 mate
I dont see any defence after Na6 with Kc8 amd Ne6-c7 mate.
Something along the lines of Na6, Ne6, Kc8 and Nc7 mating.
From Spain…
1)Na6 win
1)Na6,Nf2
2)Kc8!,Nd3
3)Ne6,Nf5
4)Nec7+,Bc7
5)Nc7++
1)Na6,Ng3
2)Kc8!,Ne4
3)de4,d3
2)Ne6,d2
3)Nec7+,Bc7
4)Nc7++
Greetings from Spain
I suggest 1. Na6 to set the black king in a prison. The continuation may be:
1. … Ng3
2. Kc8 Nf5
3. gxf5 g4
4. Nc6 g3
5. Nxc7+ Bxc7
6. Nxc7 mate
White sets up a mating net that Black can’t escape from.
1 Na6!
Blocking the pawn so it can’t advance and give the King room.
1 …. Ng6
This stalls mate by a move. 1… Nf7 isn’t any better, as White’s Pawns prevent the Knight from safely reaching the squares of e4 or c5. Bishop or Pawn moves allow mate a move faster.
2 Kc8!
Blocking the King’s escape to b7 or b8 and relieving the Knight on d8 of the duty of guarding the former.
2 …. Ne4
2….Nf5 meets the same fate. Black hopes that White is careless. If 3 Ne6? Nd6+ will drive White’s King away.
3 exf4 e3
Nothing else is any better.
4 Ne6 e2
5 Nec7+
Or 5 Nac7+
5…. Bxc7
6 Nxc7#
6 Nxc7#
Since e4 and f5 are controled by white pawns and black N cannot come to the rescue white wins with 1.Na6 2.Kc8 3. Ne6 4. Nc7+ 5.N:c7 mate
I think white might have to try for mate since everything else might well lose due to the weak pawns at e3 and g4, and if so, I think he needs to prevent a5 immediately so that the black pawn can be used as a mating aid on his king. So
1. Na6
The idea here is to bring the white king to c8, the other knight to e6, then do a type of smother mate with Nec7 followed by Nc7#. Black cannot get his king out of the a8 hole in time since it takes one move to clear b8 of the bishop (and the a6 knight even covers that square after the first move).
Now, looking at this position, there is clearly no defense. With any bishop move, white just proceeds with Kc8 (or on 1. …Bc7 just plays 2.Kc7 then 3.Kc8) and Ne6 followed by the unstoppable mate. If black has a defense at all, it must come from bringing the knight back in time to defend c7 or harrass the white king from b6 or d6, but I don’t see how that works:
1. …..Nf2
2. Kc8 Ne3
3. Ne6 and it is over, there is clearly no path for the knight.
So, Na6 definitely wins, unless I am missing something really, really silly.
1. Na6! Nf2?
2. Kc8! (any move; for ex. Be5)
3. Ne6! (any move; for ex. Nf2)
4. Nec7+ Bxc7 (for ex.)
5. Nxc7++ ..
i am sure i have missed something…
White mates by Nh6, Kf8, Ne6 and N(either)f7
Black is powerless to stop this.
