Black cannot make a mate line longer than the number of moves given in the problem (assuming the problem's author correctly constructed the problem). For instance, a mate in 65 puzzle cannot be extended to a mate in 225.
The most common orthodox chess puzzle takes the form of checkmate in n moves. The puzzle positions are seldom similar to positions from actual play, and the challenge is not to find a winning move, but rather to find the (usually unique) move which forces checkmate as rapidly as possible.
The current record for the longest selfmate problem is a selfmate in 203, composed by Karlheinz Bachmann and Christopher Jeremy Morse in 2006. [3] The puzzle is based on a 1922 342-move composition by Ottó Titusz Bláthy, which was later found to be cooked.
A chess problem, also called a chess composition, is a puzzle set by the composer using chess pieces on a chess board, 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 defence.
The checkmate is named after Richard Réti, who delivered it in an 11-move game [24] against Savielly Tartakower in 1910 in Vienna. It works by trapping the enemy king with four of its own pieces that are situated on flight squares and then attacking it with a bishop that is protected by a rook or queen.
Plaskett's Puzzle is a chess endgame study created by the Dutch endgame composer Gijs van Breukelen (February 27, 1946 – December 21, 2022) around 1970, although not published at the time. Van Breukelen published the puzzle in 1990 in the Netherlands chess magazine Schakend Nederland .
Some chess puzzles are not really puzzles at all. In the diagram, White is asked to checkmate Black in six moves. The joke in this case is that, by the rules of chess, White has no choice in the matter; the only legal moves lead directly to the "solution": 1. d4 b5 2. d5 b4 3. axb4 a3 4. b5 a2 5. b6 a1=any 6. b7#
If Black promotes, then the only way for White towards a forced checkmate in the stipulated number of moves is to promote a pawn to the same piece to which Black promoted. Joseph Ney Babson [ it ] (1852–1929), the task's eponym, first conceived of the task in 1884, but never solved it. [ 1 ]
