White to play and mate in two moves
In the series of problems which will be given daily for solving the key move will not be a checking move but a quiet one by white. The solution will be given the next day along with the composer’s name, the name of the magazine in which published and the date of publication
(Solution will be posted tomorrow)
Preamble
A chess problem, also called a chess composition Is not a position arising out of an actual game, but has been composed for the specific purpose of presenting a thematic idea with difficult key and attractive mates not often seen in the over the board play. In a direct mate problem white has to mate black in specific number of moves against any black defence. The key to such problems are invariably quiet non-checking moves. Solving problems help improve quick grasp of positions, accurate and faster calculations and above all visualizing mating positions. With this in view “Problem of the Day’ is presented from to-day -one problem each day.The solution to the problem will be given the next day along with the composer’s name, magazine’s name and the date of publication.
To quote GM John Nunn from ‘Solving in style’ “One of the most frequently debated questions about chess is whether it is a sport or an art.If the hurly burly of tournament play emphasizes the sporting aspect then the artistic element finds its best expression in the world of chess composition.Chess problems are an unsual art form in that the solvers have to participate actively by solving the problem in order to appreciate the artist’s message”
