White to play and win

In this battle of mutual passed pawns, White has an extra piece, but in most positions, if the pawns are eliminated, the result will be a draw. White starts off with

1. Nf3+ Kc3

1… Kd3 is less good, because of 2. e7 Nd7 3. Nxd2 Nf5 4. Bb1+ winning.

2. e7 Nd7

2… d1=Q? 3. exf8=Q is obviously hopeless.

3. Nxd2

3…Nf5!

White wins at once after 3… Kxd2 4. Kg5, when his pawn queens.  Now, however, 4. e8=Q? fails to 4… Nf6+ 5.Kg5 Nxe8 6. Ne4+ Kb2! and White can only emerge a useless piece ahead. In order to win, he needs to ensure he wins a further piece for his e-pawn, since three minor pieces versus one is a theoretical win, even with no pawns on the board.

4. Ne4+!  Kd4

But now what? Promoting to a queen allows 5…Ng7+, and under-promoting loses the knight on e4. However…

5. e8=N! Kxe4 6. Bb1+

Black must hang on to his Nf5, else he will be two pieces down, and 6…Kf4 7.Ng6+ is no good. Hence…

6…Ke5  7. Ng6+ Ke6 8.Ba2# 



A beautiful mid-board mate has been conjured up from nowhere.
