White to move. How should White proceed?
1k1r4/1P4r1/K3bN2/4N2p/p2n4/B2p1n2/4p3/2R5 w – – 0 2
I think this should do it:
1. Nfd7+ RgxN
2. NxR+
if 2. … BxN, then 3. Bd6 mate
if 2. … RxN, then 3. Rc8 mate
Bd6+ would have sealed the deal if not for the rook recapturing the bishop with check. However, the knights can help:
Ned7+! R7xd7
Nxd7+ and mate follows with either Rc8 or Bd6
1.Nfd7 ch (or 1.Ned7 ch) 1…Rgxd7 [ if A) 1…Bxd7? 2.Bd6# 1-0…B) 1…Rdxd7? 2.Rc8# 1-0] 2.Nxd7 ch Bxd7 (2…Rxd7 3.Rc8# 1-0) 3.Bd6# 1-0 (RIGF)
Easy, 1. Ned7+ Rgxd7 (if ..Rdxd7 then 2. Rc8#; if ..Bxd7 then Bd6#), 2. Nxd7+ and mate to follow.
Hello
1. N6d7+ ( or N5d7+) , R7xd7
2. N5xd7+ ( N6xg7+ )
2 options for black
A)
2. ….. , Bxd7
3. Bd6#
B)
2. ….. , Rxd7
3. Rc8#

well, that one’s easy:
1. N(any)d7+ Rgxd7
2. Nxd7+ Rxd7
3. Rc8#
2. … Bxd7
3. Bd6#
1. … Bxd7
2. Bd6#
1. … R8xd7
2. Rc8#
greets, jan
1.Nfd7+! Rgxd7 (1…Bxd7 2.Bd6#; 1…Rdxd7 2.Rc8#) 2.Nxd7+ and mate next move.
Bd6+, then the 2 N check in succession in d7 and finally the rook mates in the back rank. El Fede.
1. BD5+ RXD5
2. RC8++
An easy one:
First mislead that old Rook guy by giving an Bishop check on d6. Then, when the eights rank is so vulnerable your Knights jump one after the other on that d7 square to block or extinguish Black’s protector of the square c8. And finally “end them” (the slings and arrows of an outrageous fortune, Hamlet) by a not very sophisticated checkmate through your own Rook boy on c8. Why never my positions allow an effectfull conclusion like this?
Not Bd6+? because the black rook then captures the bish with check!
Just check with either knight on e7. The bishop can’t capture because of Bd6++, and the Rook on d8 can’t capture because of Rc8++. So after 1 Nd7+, Rg7xd7 is forced. Then 2 Nxd7+, and it’s the same situation: if …Bxd7, then Bd6++; and if …Rxd7, then Rc8++.
1, Bd6+ Rxd6
2, Nd7+
2, if black moves: Bxd7
3, Nxd7+ Rxd7
4, Rc8#
2, if black moves: Rxd7
3, Rc8#
Yes, Bd6 wins. It takes his rook off the back rank and then you can use your knights to block his bishop from c8.
Much like the puzzle from yesterday, the black king is hemmed in tight with four pieces looking to mate him where he stands. The two knights are looking to do it from d7, but that square is three times guarded at first glance, but one of those can’t be played (Bd7) because it blocks the d8 rook’s guard on the threat of Bd6. In addition, this same rook guards against Rc8#. That piece is the overworked one you are looking for:
1. Nfd7 Rgd7 (Bd7 2.Bd6#;Rdd7 2.Rc8#)
2. Nd7 an no matter which piece black takes with, mate follows by either 3.Bd6 or 3.Rc8
1.Nfd7+ Bxd7
2.Bd6#
1.Nfd7 Rdxd7
2.Rc8#
1.Nfd7# Rgxd7
2.Nxd7 and black has a choice:line 1 or line 2
This is some sort of a Novotny if I am not mistaken.
I don’t understand
1.Bd6+ Rxd6+
You can’t move your knight on d7 but c6
2. Nc6+ Nxc6
Bd6# is prevented by the Black Rd8; Rf8# is prevented by the Black Rd8 and the Black Be6.
But the lines of these two pieces cross at d7, allowing a Novotný interference:
1. Nfd7+ Rgxd7 (1. … R8xd7 2. Rf8#; 1. … Bxd7 Bd6#)
2. Nxd7+ and mate next move.
Knight to d7 and check (either knight).
Rg7xd7 is forced, whence
Knight takes rook at d7 and checks again.
If the rook takes the knight, moving the rook to c8 is checkmate. If the bishop takes, then Bishop to d7 is checkmate.
I think Nfd7 is better and quicker.
1. Nfd7+ then if 1… R7xd7
2. Nxd7+ Rxd7
3. Rc8#
if, at any time…
1… Bxd7
2. Bd6#

1.Nd7+
A) 1…Bxd7 2.Bd6 mate
B) 1…Rxd7 2.Nxd7 Rxd7 3.Rc8 mate
This is called a Novotny interception for those interested in chess composition.
