win not draw!

A puzzle taken from ''Modern end-game studies for the chess player'' published in 1959.

Quote: 'The Lancashire County player, D Joseph, has published little, but the following masterpiece is worthy of the worlds greatest end-game composers. Out of a miniature of only six pieces he has constructed a wonderful study well-nigh perfect of its kind.'

i've seen it somewhere, but couldn't solve it again... very nice!

nice one

Couldn't he have accomplished the same win by QxA1, taking the queen and black has no legal moves?

Qxa1 is stalemate which is a draw, thats the whole point of the puzzle, white wins!

:S really hard, but nice exercise :P

!!!!!!!!!!!!

I had seen it before, but was still fun trying to recall the correct moves. A great problem.
