Best Wishes for all!
As is customary this time of the year, riddles and problems have started to appear (one per day from 25-12-2008 to 01-01-2009) at the web address Chessbase Puzzles.
Problems for year 2008 :
25-12-2008 : Play Santa-giving-presents. Read biographical details of John Nunn, who selects and annotates this year's problems. Solve the direct-mate moremover. Do not hesitate to give Knight (easy) and Queen (where?) in order to achieve eventually mate with subpromotion of c7.
26-12-2008 : In the five-mover helpmate (where black plays first) close for a while the Bishop, which will go finally to g8.
27-12-2008 : The study can start with a checking-key, (since Black can mate in 3 moves), let us say with the Bishop on h4.
28-12-2008 : In the six-mover selfmate, (White plays and forces Black to win with mate,) two knights are sacrificed first.
29-12-2008 : To avoid the diabolical trap of stalemate in this study, give the Rook on the fourth move and the Queen on the tenth.
30-12-2008 : Eleven Black moves (begin with Re5, end with Be8) and then one White move (dxe8=Q) stalemate! It is very interesting to discover the intermediate moves.
31-12-2008 : For the five-mover selfmate, the Bishop makes a big clockwise round to d2 and the Queen is sacrificed on the other side.
01-01-2009 : Starting from the initial placing of the pieces for playing a game, we reach the position of the diagram after the ninth move of the White. The Shortest Proof Game is a nice problem with Retroanalysis. (The page that shows this problem contains a form on the upper left corner for everyone wanting to send solutions and comments to John Nunn).
Happy New Year!
