**Award Winning Chess Problems** - Burt Hochburg (2005)

Each of these problems has been awarded a top prize in one of the innumerable problem competitions (tourneys) that have been held all over the world in the last century and a hal£ Problem composers submit their works to committees whose members comprise other composers, problem judges, and problem magazine editors. These experts determine the prizewinners in several categories.

All orthodox chess problems, like those in this book, stipulate that White makes the first move (the key) and checkmates Black in a specified number of moves no matter what Black plays. The stipulation is inviolable: mate must be accomplished in exactly the number of moves specified, no more, no fewer. There is only one correct key for each problem.
