White to play and win

Solution

1 Nce7+ is the obvious first move, the only question being 'does it win'? It is simple to see that if 1…R2e7, 2 Qe7 is terminal- black might be able to grovel by. 2…Qe6, but the only realistic try is 1…R8e7 when 2 Qe7?? loses to 3 Qc2 mate, so 2 Rd8+[] Re8[] and now 3 Qf8+!! and it is game over.

Quite a nice puzzle: Qf8+ came to me fairly easily, but had it not done so, then following Purdy's maxim of consider all biffs' which includes 'consider all checks' then the solution would have been found anyway.
