Fool's mate was named and described in The Royal Game of Chess-Play, a 1656 text by Francis Beale that adapted the work of the early chess writer Gioachino Greco. [2]Prior to the mid-19th century, there was not a prevailing convention as to whether White or Black moved first; according to Beale, the matter was to be decided in some prior contest or decision of the players' choice.

The shortest stalemate with all of the pieces on the board, composed by Charles H Wheeler, [27] occurs after 1.d4 d6 2.Qd2 e5 3.a4 e4 4.Qf4 f5 5.h3 Be7 6.Qh2 Be6 7.Ra3 c5 8.Rg3 Qa5+ 9.Nd2 Bh4 10.f3 Bb3 11.d5 e3 12.c4 f4 (minor variations are possible).
This difference is typical of many endgames. DTC is always smaller than or equal to DTM, but the DTM metric always leads to the quickest checkmate. Incidentally, DTC = DTM in the unusual endgame of two knights versus one pawn because capturing the pawn (the only material Black has) results in a draw, unless the capture is also checkmate.
Philidor's mate, also known as Philidor's legacy, is a checkmating pattern that ends in smothered mate. This method involves checking with the knight forcing the king out of the corner of the board, moving the knight away to deliver a double check from the queen and knight, sacrificing the queen to force the rook next to the king, and mating with the knight.
Tsume problems usually present a situation that might occur in a shogi game (although unrealistic artistic tsume shogi exists), and the solver must find out how to achieve checkmate. It is similar to a mate-in-n chess problem. The term tsumi (詰み) means the state of checkmate itself. The verb form is tsumu (詰む) "to checkmate
Fool's mate – also known as the Two-Move Checkmate, it is the quickest possible checkmate in chess. A prime example consists of the moves: 1.f3 e5 2.g4 Qh4# Scholar's mate – checkmate achieved by the moves: 1.e4 e5 2.Qh5 Nc6 3.Bc4 Nf6? 4.Qxf7#. The moves might be played in a different order or in slight variation, but the basic idea is the ...
This table summarizes results from games compiled from several game databases, where this position was reached. "Max DTC" is the maximum number of moves in depth to conversion, either a checkmate or conversion to a winning endgame via promotion of the pawn or capture of the opposing rook.
The two knights endgame is a chess endgame with a king and two knights versus a king. In contrast to a king and two bishops (on opposite-colored squares), or a bishop and a knight, a king and two knights cannot force checkmate against a lone king (however, the superior side can force stalemate [1] [2]).
