The checkmate is named after the famous Italian checkmate cataloguer Gioachino Greco. It works by using the bishop to contain the black king by use of the black g-pawn and subsequently using the queen or a rook to checkmate the king by moving it to the edge of the board. [16]
A checkmate may occur in as few as two moves on one side with all of the pieces still on the board (as in fool's mate, in the opening phase of the game), in a middlegame position (as in the 1956 game called the Game of the Century between Donald Byrne and Bobby Fischer), [3] or after many moves with as few as three pieces in an endgame position.
Each type of piece moves in a distinct way. The object of the game is to checkmate the opponent's king; checkmate occurs when a king is threatened with capture and has no escape. A game can end in various ways besides checkmate: a player can resign, and there are several ways a game can end in a draw.
A king plus bishop versus a king plus bishop with the bishops on the same color is also a draw, since neither side can checkmate, regardless of play. Situations where checkmate is possible only if the inferior side blunders are covered by the fifty-move rule. [216] See Draw (chess) § Draws in all games. interference
In the Frankenstein–Dracula Variation of the Vienna Game (1.e4 e5 2.Nc3 Nf6 3.Bc4 Nxe4), threatening checkmate with 4.Qh5 is the only way for White to play for an advantage. The Modern Defense, Monkey's Bum variation involves White threatening a Scholar's mate with an early Qf3.

[2] Draw by resignation: Under FIDE Laws, a game is drawn if a player resigns and no sequence of legal moves would allow the opponent to checkmate that player. [2]
