Message 775192 - Posted: 29 Jun 2008, 11:16:44 UTC

No wins for Chess challenge 47
solution;
1...Ne2+ A primary function of this move is one of interference. If White goes to h2 with the king, Qg2 is mate!
2.Rxe2 Rf1+ Enticing the king away from h1. Again, if the king tries to hide on h2, then Qh1 is mate.
3.Kxf1 Qh1+
4.Kf2 Ng4++


Something a bit easier now
Chess challenge 48

Well done Beethoven, I'm going to expose your correct answer for all to see;

1. ...Qe6-e1+
2. Rd1XQe1 (forced); Re8xRe1++

This 50th chess challenge came from Nigel Short, one of Britain's greatest chess players. So well done for getting that one Beethoven.

After searching out 50 chess puzzles I am going to call it a day. I hope someone else will step in and become the chess host, and I look forward to trying to solve the chess puzzles rather than finding them.

Thanks for all your contributions. Perhaps a moderator will be good enough to lock this thread.
