Puzzles from Chessbase

It is many years now that Chessbase, beyond presenting chess news and persons and games, beyond advertising chess software and books, also gives a series of puzzles, one per day, starting on December 25th thru New Year Day.
See all previous presentations here.

This year, the world champion on chess problem solving John Nunn edited the Christmas puzzles 2010, that have already started appearing. After the completion of the series, you may send the solutions there, and the best solver will receive the new book [1001 Deadly Checkmates] by John Nunn.
