In a helpmate in n moves, Black moves first, then White, each side moving n times, to culminate in White's nth move checkmating Black. (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.)
Among English speakers, the scholar's mate is also known as schoolboy's mate (which in modern English perhaps better connotes the sense of "novice" intended by the word scholar's) and Blitzkrieg (German for "lightning war", meaning a quick victory). [8] The names of the scholar's mate in other languages are as follows:
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 puzzle is based on a 1922 342-move composition by Ottó Titusz Bláthy, which was later found to be cooked. [citation needed] Prior to December 2021, the record for the longest selfmate problem was a 359-move problem, created by Andriy Stetsenko in 2016. [4] Unfortunately, this problem was later found to be cooked, as a shorter solution exists.
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.
This article covers computer software designed to solve, or assist people in creating or solving, chess problems – puzzles in which pieces are laid out as in a game of chess, and may at times be based upon real games of chess that have been played and recorded, but whose aim is to challenge the problemist to find a solution to the posed situation, within the rules of chess, rather than to ...
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 ]
A directmate with the stipulation "White to move and checkmate Black in no more than n moves against any defence" where n is greater than 3. In composition tourneys, there are often separate classes for more-movers, two-movers and three-movers (as well as classes for helpmates, selfmates and others).
