Nf5 + then force mate
1.Qh6+ Kg8 2.Qh8#. It took me 2 seconds to find it.
Knight checks and if the king moves backward, queen mates. If king moves forward to f6, Rxd6+ followed by queen mating.
Hi Susan,
I believe that the idea of Qh6+ is strong, but the move order is important. White should first play
1.Nf5+ !… If Black plays Kf6,
then 2. Rd6+ is fatal.
If the knight is taken, then white can proceed with Qh6+
Nf5 looked a little TOO obvious but well….there it is!!! lol.
NF5 check….pretty obvious.

Susan. you really got to put tougher stuff up as problems.
1. Nf5+ Kf6 2. Rxd6+ Re6 3. Qh8
or 1. Nf5+ Kf8/g8 2. Qh8
1. Nf5+ Kf6 (gxf5? Qh6+! then Qh8 mate)
2. Qh4+ g5 (Ke6 Rxd6#)
3. Qh6+ Ng6
4. Qg7+ Ke6
5. Rxd6+ mate
Nf5+
If black capture then Qh6+ followed by Qh8 is mate.
So forced is Kf6. then, for example,
Rxd6+ Re6
Qh4+ g5 (or Kg7 Qh8 mate)
Qh8+ Kg6
Rh6 mate
1. Nf5+!! (if Qh6+ then 1… Kf6 of course)
After 1.Qh6+ what if 1…Kf6
1.Nf5+
if 1…gxf5
2.Qh6+ Kg8
3.Qh8#
if 1…Kf6
2.Rxd6+ Kg5 (or 2…Re6 3.Qh4+ g5
3.Qh4# 4.Qh8+ Kg6 5.Qg7#)
if 1…Kg8
2.Qh8#
if 1.Kf8
2.Qh8#

1. Qh6+ doesn’t work since king escapes through f6…
Correct is 1. Nf5+… if black takes on f5 just then Qh6+ works. If king goes through f6 Qh4+ continue with checkmate in 3.
It took me 1 second to find it. =)
Also possible is
1.Nf5+ Kf6
2.Qh4+ g5 (or 2…Ke6 3.Rxd6#)
3.Rxd6+ Re6
4.Qh8+ Kg6
5.Qg7#
1.Qh6+ Kf6 and White lose …in 2 seconds!!!
Better seems to be:
1.Nf5+ then:
1…Kg8 (or 1…Kf8) 2.Qh8 mat
1…gxf5 2.Qh6+ Kg8 3.Qh8 mat
1…Kf6 2.Rxd6+ Re6 (or 2… Kg5 3. Qh4 mat)3.Qh8 Kg5 4.Qh4 mat
Anonymous,
Well, why would black go to g8? Why not Kf6? That took me about 3 seconds.
White appears to have a mate in four, beginning with
1.Nf5+ Kf6 (all other Black replies lose quicker)
2.Rd6+ Re6
3.Qh4+
By the way, Anonymous at 6:40 pm: when my reply is the first one shown, I’ve found out it’s usually incorrect!
Lol 1.Qh6+ Kf6 no mate… But 1.Nf5+! Does. 1.Nf5+ Kf6 (gxf5 allows Qh6+ then Qh8# and Kf8 or g8 allows Qh8#)2.Rxd6+ Re6 3.Qh8+ Kg5 4.Qh4#….
@Anonymous… who states: “1. Qh6 […] took me 2 seconds to find it” –> what about Kf6?! No mate, all sorts of problems.
Anyway, I find this a rather difficult problem. I think the solution is: 1. Nf5+ if gxf, 2. Qh6+ – Kg8, Qh8++. More tricky is: 1. Nf5+ – Kf6, Qh4 – g5 (if Ke6, Nd4++), Qh6+ – Ng6, Qg7+ – Ke6, Rxd6++
1.Nf5 g6xf5 2.Qh6+ Kg8 3.Qh8++

I would be tempted by Nf5
1. Nf5 Kf6 (Kf8 or Kg8 2. Qh8#)
2. Rd6 Kg6
3. Qh4#
So, black must take the knight at move 1:
1. Nf5 gf5
2. Qh6 and mate follows as Kf6 is no longer an option for black.
Seems to me that White can get a draw out of this position, with best play by Black. With any other play, White wins.
1. Qh7+ Kf6
2. Qh4+ Kg7, draw by repetition.
If Black tries to get rid of the nuisance check and win with that pawn at b3 and the Q/R doubling on the a file, disaster.
1. Qh7+ Kf8
2. Qh8+ Ke7
3. Nxc6+ Ke6 (only move)
4. QxR+ Kf6
5. Qe7+ Kg7
6. NxQ RxN
7. QxB bxa+
8. Kb2 1-0
Mark
1.Nf5+ then the rest is force move for black
Nf5+ leads to mate against any defense
1.Nf5 gf5
2.Qh6 Kg8
3.Qh8++
1.Nf5 Kf6
2.Rd6 Re6
3.Qh8++
Tommy K. says
1.Nf5+
if …gxf5
2.Qh6 Kg8 (only move)
3.Qh8#
1.if …Kf8 or Kg8
2.Qh8#
1.if …Kf6
2.Rxd6+
if …Kg5
3.Qh4#
if 2….Re6
3.Rxe6+ Kxe6
4.Qd6#
if 3….Kg5
4.Qh4#
if 3….fxe6
4.e5+ Kf7
5.Qh7+ Kf8 (5…Ke8, then Qe7#)
6.Qg7+ Ke8
7.Qe7#
if 4….Kxf5
5.Bd3+ Kg5
6.Qg3# of Qh4# or Qh6#
if 4….Kg5
5.Qh4+ Kxf5 (only move)
6.Qe4+ kg5
7.Qg4#
I think I got all the variations!
This one was fun. Thank you Susan.
1. Nf5+ Kf6
2. Rxd6+ Re6
3. Qh8+ Kg5
4. Qh4++
if
1. … gxf5
2. Qh6+ Kg8
3. Qh8++
if
2. … Kg5
3. Qh4++
ngy
1. NF5ch, if pxN, then Qh6ch and Qh8mate.
If after 1. Nf5ch and Kf6, then 2.Qh5ch g5 3.Qh6 ch Ng6 4. Rxd6mate
Nf5!!
why settle for a draw when white can play
1. N-f5+ and if K-f6,
2. R-d6+ R-e6
3. Q-h8++
1. Nf5+ Kf6
2. Rxd6+ etc.
1.Nf5+ Kf6 (1.gf5 Qh6+) 2.Qh4+ +-
Mark
After 3.Nxc6
what about 3…Nxc6
White can get a clear win out of this . The winning move is 1) Nf5+
now if black plays
1) …gxf5
2)Qh5+ Kg8 (only move)
3) Qh8# .
Or if black plays
1)…. Kf8 or Kg8
2) Qh8#
So the only move left for black is 1)…Kf6
2) Rxd6+
2)….Kg5 is suicidal for black because of 3)Qh4#
so black is forced to play
2)… Re6
3)Qh4+ g5(only move)
4)Qh6+ Ng6(only move)
5) Qg7# .
PS: it took me 5 min to solve this . . . Lol . .
1. Nf5+ Kf6 or gxf6/Kf6 2. Qh6+
Thats quite simple.
1. Nf5+! Kf6
( 1… Gxf5 2.Qh6+
2… Kg8 3.Qh8#)
2. Rxd6+ Re6
3. Qh8+ Kg5
4. Qh4#
Mark, after
1. Qh7+ Kf6
2. Qh4+
Black can play g5, and his king escapes.
Instead, 1.Nf5+! leads to mate.
1. Nf5+ gxf5 2.Qh6+ Kg8 3.Qh8#
nf5+ wins..kf6 qh4 g5 qh6 ng6 qg7 ke6 rd6 mate
Tommy K. says:
My apologies! Some prankster removed the black
knight from the e5 square, so my previous post
was all for naught. Let’s try this again with
all the pieces present this time! Same first move
1. Nf5+ if Kf8 or Kg8 then Qh8#
if …gxf5
2. Qh6+ Kg8(only move)
3. Qh8#
if …Kf6
2. Rxd6+ Kg5
3. Qh4# or Qh6#
if 2….Re6
3. Qh8+ Kg5
4. Qh4#
1.Nf5 +-
Nf5+ gxf
Qh6#
If 1 … kf6
Qh4+ ke6
Nd4#
1.Nf5+ gf5:
2.Qh6+ Kg8
3.Qh8 ++
or
1. … Kf6
2.Rd6+ Re6
3.Qh8+ Kg5
4.Qh4++
1.Nf5+! a modifying sacrifice if 1..Kf6 2.Rxd6+ Re6 3.Qh8+ Kg5 4.Qh4 mate
so 1…gxf5 2.Qh6+! Kg8 3.Qh8 mate
