1. Kf2 is obvious, limiting black’s moves, .. Kh1
2. Nf5! now h2 is prevented because of Ng3 mate, so .. Kh2
Now the white knight takes a detour to f3:
3. Ne3 Kh1
4. Nf1 h2
5. Ng3# 1-0
1. Kf2 – Kh1
2. Nf5 – Kh2 (h2, Ng3#)
3. Ne3 – Kh1
4. Nf1 – h2
5. Ng3#

White can mate in 5 moves:
1. Kf2 Kh1
2. Nf5 Kh2
2. … h2
3. Ng3#
3. Ne3 Kh1
4. Nf1 h2
5. Ng3#
Its a mate in 5. The idea is to put white knight in f1 when black king is in h1 and pawn is in h3.
1.Kg2 Kh1
2.Nf5 Kh2 (2…h2 3.Ng3#)
3.Ne3 Kh1
4.Nf1 h2
5.Ng3#
Hi Susan Polgar,
My power supply went down for a while few minutes before – so posting my comment for this puzzle had delayed for a while.
Well,this chess puzzle leads to draw / stale mate like a cake walk.
For White piece to win,strategy should be to avoid draw /stale mate,eliminate pawn then fork the Black piece king by making white piece king & knight move alternatively & adjacently to fork the Black king and mate the game.
1.Kf2 Kh1
2.Ne2 Kh2
3.Nf4 Kh1
4.N*h3 Kh2 [ From here on White has many possibilities to fork the Black piece king and mate the game – so rest of the moves are open for other blog users to fill in ]
But if Black piece player is a beginner then White piece can mate 3 moves.
1.Kf2 Kh1
2.Ne2 h2
3.Ng3++ mate [ This will not happen,unless Black piece player is the beginner ]

King to F2 prevents black from moving the king and promoting the pawn. The knight can then come over and at least ensure a draw.
Got it.
1.Kf2 Kh1 2.Nf5 Kh2 3.Ne3 Kh1 4.Nf1! h2 5.Ng3 mate.

i remember, we already had quite a few of these, so let´s see, how this one works:
1. Kf2 Kh1
2. Nf5 Kh2
3. Ne3 Kh1
4. Nf1 h2
5. Ng3#
2. … h2
3. Ng3#
greets, jan
1. Kf2 Kh1 2. Nf5 Kh2 3. Ne3
Kh1 4. Nf1 h2 5. Ng3#
1.Kf2 blocking Black King’s escape 1…Kh1 only move.
2.Nc2 Kh2
3.Ne3 Kh1
4.Nf1 h2 Only move.
5.Ng3#

This is a forced mate in 5,not a draw.
1. Kf2 Kh1
2. Nf5 Kh2
3. Ne3 Kh1
4. Nf1 h2
5. Ng3#

Hello
1. Kf2 , Kh1
2. Nf5 , Kh2 ( if h2 3. Ng3# )
3. Ne3 , Kh1
4. Nf1 , h2
5. Ng3#
Greetings from Spain
This is an opposition problem. First, the win from the given position is 1. Kf2 Kh1 2. Nf5 Kh2 3. Ne3 Kh1 4. Nf1 h2 5. Ng3#. Repositioning the knight, wins are also possible from c5, c3, c1, d2, d6, e2, e3, e4, e7, f4, f5, f6, g1, g5, g7, h4, h5, & h6. What do these have in common? First, the dark squares (all choices except e2, e4, f5, & h5) are solved just like the given problem: White king to f2 to hold the king in place, then maneuver the knight to f1 passing through e4 or f5 (prepared for mate on g3 should Black attempt stalemate with … h2). The light squares e2, e4, f5, & h5 also work because they guard g3 so that White can tempo the king to f1 before f2. The other light squares are draws because the even-odd movement of the knight turns the mate into a stalemate. The other dark squares are draws because they are too far from g3 and Black can stalemate with … h2 before the knight can answer with checkmate from g3.
1. Kf2 Kh1
2. Nf5 Kh2 (h2? 3. Ng3++)
3. Ne3 Kh1
4. Nf1 h2

2. Nf5 Kh2 ( if h2, Ng3 mate)

Hi Venky, you are a great Indian Nut as I do.
Lord Venky(Venkateswara) gave me following solution.
1 Kf2 Kh1
2 Nf5 kh2(if 2… h2 3Ng3#)
3 Ne3 kh1
4 Nf1 h2 ( now forced)
5 Ng3#
The moral of the story is if opponent does not walk into mate voluntarily force him into it.
1. Kf2 (only move to keep Black king out of both g2 and g3)
1. … Kh1 (only move)
2. Nf5 Kh2 […h2?; Ng3 mate]
3. Ne3 Kh1 (only move)
4. Nf1 h2 (only move)
5. Ng3 mate
Oops…for all white moves, I gave it as king moves into the g-file. My bad. It moves to the f-file. Corrected solution –
1.Kf2 Kh1
2.Nf5 Kh2 (2…h2 3.Ng3#)
3.Ne3 Kh1
4.Nf1 h2
5.Ng3#
The first comment was sufficient; why another 22?
Because, dear Anonymous [Tuesday, April 5, 2011 3:12:00 PM CDT], we like to work out the problems by ourselves before looking at the proposed solutions. Then we also like to show that we worked them. Simple, yes? Don’t tell me that you look at the solution first, and then decide to work the problem if no one has got it right yet.
