(In a helpmate in 2 for example, sometimes abbreviated h#2, the solution consists of a Black move, a White move, a second Black move, then a second White move, giving checkmate.) Although the two sides cooperate, all moves must be legal according to the rules of chess. The example problem illustrated is a helpmate in 8 (or h#8) by Z. Maslar ...
Tivadar Kardos (September 26, 1921 in Budapest – May 15, 1998) was a Hungarian chess composer and an author of chess-related material. An academic by trade, he composed over 400 chess problems. He focused on two-move problems, as well as self-and helpmates. He was chairman of the Budapest Chess Problem Committee.
A chess problem, also called a chess composition, is a puzzle created by the composer using chess pieces on a chessboard, which presents the solver with a particular task.. For instance, a position may be given with the instruction that White is to move first, and checkmate Black in two moves against any possible defen
Dawson published his first problem, a two-mover, in 1907. His chess problem compositions include 5,320 fairies, 885 directmates, 97 selfmates, and 138 endings. 120 of his problems have been awarded prizes and 211 honourably mentioned or otherwise commended. He cooperated in chess composition with Charles Masson Fox.
In 1936, Alain C. White published A Genius of the Two-Mover, which included 100 of the 300-or-so problems that Mansfield had composed over the past 20 years; and, in 1944, White also published Mansfield's Adventures in Composition – The Art of the Two Move Chess Problem in a limited edition. This book was re-published in the UK in 1948. [2]
Chess problems are divided into orthodox and heterodox types, both covering a variety of genres. Orthodox problems employ the standard rules of chess and involve positions that can legally arise from actual gameplay. The most common form of orthodox problem is the directmate, which stipulates checkmate in n moves, usually two or three. The ...
A player can either move one piece twice (this is the source of the famous trap in the "balanced" version of the game where White opening with pawn-two appears to be trivially busted by an unprincipled defense with the pawn on an adjacent file) or move two different pieces on their turn.
The device can be understood by reference to the problem shown here, a mate in two moves (white moves first, and must checkmate black in two moves against any defence). The key (first move of the solution; see Glossary of chess problems) is 1.Nb2 (see algebraic notation). This interferes with black's rook and bishop, and whichever of those ...
