White to move and mate in 5.
1. Kg3 Kf1 2. Bd3+ Kg1 ( 2. … Ke1 3. Nf3# ) 3 Nh3+ Kh1 4. Be4#
I think what I did with the Nf3+ that I thought was mate was I checked that all the dark squares were controlled and then just left it at that because I lost track of what I was thinking.
If 2) … Ke1, 3) Nf3 is not mate, since the d1 square is quite accessible. However, this is the familiar N + B mate, either:
1) Bd3 — if Kh2,
2) Kf2, Kh1
3) Bf1, Kh2
4) Nf3+, Kh1
5) Bg2+ OR
****
1) Bd2 — if Kh1
2) Kf2, Kh2
3) Bf1, Kh1
4) Bg2+, Kh2
5) Nf3#
Lenny you lost one move in the second variation.
1. Bd3 Kh1
2. Kg3 Kg1
3. Nh3+ Kh1
4. Be4#
Correct! Mate in 4 is better than mate in 5! Nice catch, Alena.
I can fortunately play this ending from this position blindfolded. Of course, getting this position, where the king is corralled in the right corner, is still an ending I haven’t fully mastered so that I can easily win it against a solid player:
1. Bd3
Keeps the king in the corner by taking away the f1 square:
1. …………Kh2
If black plays Kh1, white rearranges what you see below to use the king to take away h2 rather than h3: [1. …Kh1 2.Kg3 Kg1 3.Nh3 Kh1 4.Be4#].
2. Kf2
Uses the king to take away g1- both kings moves in the lines clear the line to h1 for the bishop…..
2. …………..Kh1
From here, white has two options to finish this off in 5 moves total, I just prefer this one, as does Lenny it appears…..
3. Bf1
Replaces the knight’s guard on h3 so that he can move…..
3. …………..Kh2
4. Nf3 Kh1
5. Bg2#
Like I wrote, the really, really hard part about this ending is getting to the point in the diagrammed position.
Bd3 Kh2, Kf2 Kh1, Kg3 Kg1, Nh3+ Kh1, Nf3 #
A few years ago in Raleigh NC I escaped with a draw because I traded my Knights for his pawn(s). Amazingly I believe that same week he was teaching his students not worry about the B and N mate because it is so rare. (He told me)…and something like after I got his pawn that I was cruel. He just stared at the board…made a few moves and then agreed to a draw…wow…whew I escaped!

It’s a winning position for white.
The first time this was posted, the commenters found at least, I think, three 1st moves for white to win. 1.Rb5 is one of them that Lucymarie found. I favored 1.Rg5, and others favored 1.Re5, and I couldn’t really tell you which is most accurate, but they clearly gave white near decisive advantages.

Wow!

There was a game in one of the Kasparov vs. Karpov matches (1990, I think) where Karpov, late in the match (sometime around game 20/21, think) needed a victory to even the match, and he pressed a Q+N vs Q ending for about 30 moves. If memory serves, Kasparov also had two unconnected pawns with his king and queen against Karpov’s queen, knight, and king. I remember thinking at the time that Karpov was just being stubborn in pressing the ending since I was convinced there was no way to even win the ending if Kasparov didn’t even have the two pawns. This little puzzle shows that Karpov wasn’t being stubborn for no reason- it can be won if player with just the queen is a bit careless.

The first puzzle is very very difficult. I will try to crack it.
Mate in 4 is not the shortest!
Alena, after you solve this one, there are more puzzles below these comments.
Here is the solution for the first puzzle. I don’t know how to win. I only found out how to get a draw.
V-1
1. Rc8+ Kxe7
2. Rg8 h3
3. c6 h2
4. c7 g1=Q
5. Rxg1 hxg1=Q

It isn’t a strong line.

2. Rg8 h3
3. c6 Kd6
4. Rg6+ Kc7
5. Kb2 h2
6. Rxg2 h1=Q
7. Rc2
The white’s plan is to save a pawn to secure a draw.
Well done. Yes, the second line is the most challenging for white, but it is a technical draw. I was just checking to see if you understood that last line.
At last I have found the shortest mate.
1. Kc3! Kb5
2. Nc5 Kb6
3. Rb7#
You got it.
1. Bd3 Kh1 2. Kf2 Kh2 3. Bf1 Kh1 4. Bg2+ Kh2

It’s a winning position for black.
Consider this position that arises from the main line of the solution (I pulled this position directly from the Nalimov Tablebase, though I have an analogous line in my own solution from 5 years ago).
8/8/p7/8/1P4b1/1P6/2K5/4k3 b
In reviewing my comment, it was a bit unclear to me even then if black has to force white to move the b5 to allow black to convert the black a-pawn into a b pawn. Is that the case or not?
In my opinion it’s inevitable.
