Cordingley puzzle 250 #chess

White to play and win (or not)

(Don't waste your time on this: it is cooked: maybe a quick look, and then read my comments)

Solution

What a disappointment! The last puzzle in the book, and I had hoped for a while, building up to the last day, that it would be a good day. But my daily project ends damply: I had a look at a few obvious moves (breaking through on the g file is the obvious plan) and somehow guessed it was one of those long lined Cordingley solutions which depend on a defensive inaccuracy. And, surprise surprise, it was.

The attached file contains various lines: not much more to say, today, alas.
