White to play and win
Yanofsky-Dulanto, Buenos Aires Olympiad 1939
"... White's queen is attacked and it appears that any attempt to save it permits mate. Black might have been excused for anticipating a win rather than a king-trip to the eighth rank."
The King-Hunt, John Nunn & William Cozens
So White looks doomed but in fact it's Black who's going to lose. Given that we know that in advance I don't think it's too tricky to guess what White's starting move must be; the difficult bit is analysing the line out to the end.
Finding the mate without moving the pieces would be quite an achievement for most of us I think but White had actually worked out the finish nine moves before our starting position had even arisen. From here in fact:-
If you don't fancy calculating the mate you could take a punt at how we get from our second diagram to the first.
Anyhoo, although the S&BCC blog will continue to publish every day over the festive period that's it from me for another year.
Merry Christmas and a happy new year to you all. See you again in 2009.
