W: Ka1 b6 d2
B: Ka3 b3 d3 a6
Black to play..
White pawn is unstoppable, but can you show the white win?

Since nobody else is trying, here is my attempt:

1. ... b3+
The first two moves by black are interchangable. Black's kingdoes not move because the white king would immediately come to b2.

2.Kb1 a5
3.b7 a4
4.b8N!
promotion to queen or rook would be stalemate. Promotion to bishop would not win.

4. ... Kb3 (needs to protect the pawn)
5.Nd7 a3
6.Nc4+ Kc4 (or Kb4)
7.Ne4 Kb3
8.Nc3 followed by 9.Ka2, 10.Nb1 and 11.Nxa3 wand later on also the other two pawns.

Yes, that right...
Wasnt so hard, but a nice example of underpromoting :-)
I'll try to find a harder one :-)

I sort of liked the position tho...

Okay...here's an interesting problem:
White: Kg2, Qe8, Rf2, Rh2, Nc5, Nf5, Bc4, Bg3.
Black: Kc2, Qg4, Rb2, Rd2, Nd5, Ng5, Bc3, Be6, e7
White moves and mates in 5, or Black moves and mates in 5.

Try this on for size! ^_____^;;;

1. ... Rxf2+ 2.Kxf2
(2.Kg1 or 2.Kh1 then Rb1+)

2. ... Kb1+ 3.Kg1
(3.Be2 Qxe2+ 4.Kg1 Nf3+ 5.Kh1 Qf1πŸ™„
(3.Kf1 Qd1+ 4.Be1 Qxe1πŸ™„

3. ... Qd1+ 4.Bf1
(4.Be1 Nf3+ 5.Kh1 (5.Kf1 Qe1πŸ™„ Rxh2#

4. ... Nf3+ 5.Kh1 Qf1#.

Lol...
Seems to work just fine....
I can't tell how many times I tried 1. ... Rxf2+ 2. Kg1
and got it to six or seven moves....
After you posted this solution I tried it again.. Mate in three :-)
nice thinking on my part... NOT! :-)

This is an interesting one, white to mate in 11 moves.


White= kd8 and pawns at b5 and h2
Black= ka7 and pawns at a6 and b7

I guess I just can't see it.

I'm thinking: 1. b6+ Kxb6 2. h4 a5 3. h5 a4 4. h6

Unless black or white makes a mistake...it can't be done.

It can be done, black would not take the pawn, look deeper into the position. If black took back it would just allow white to get a fast queen and win the game. 1.b6+ then what?

If black takes the pawn, can you show how white gets fast a queen and wins the game .... in 11 or less moves? Please show that. I can't do it.

Ok if black takes back mate in 12 1.b6 kxb6 2.h4 a5 3.h5 kb5 4.kc7 a4 5.kxb7 kb4 6. H6 a3 7.h7 kb3 8. h8=Q a2 9.kb6 ka3 10.Qc3 ka4 11. kc5 (black has no other move but to promote) a1=Q 12.Qb4#. Try another move for black.

But your puzzle stated mate in 11. Mate in 12 is not good enough.

The line that you give after Kxb6 is not black's only defense. I think that 2 . ... Kc5 gives black many more moves than 11 to survive.

But even after 1. b6+ Kb8, can you show that white mates in 11?

Yes that's the next move! Black has a possible draw with kb8 if white slips up, but after kb8 there is mate in 11. 1.b6 kb8 then what?
