Isemate

Isemate is a term used in the context of chess to describe a situation where two players have agreed to a draw, but one player has made a mistake in the process. The term is a portmanteau of "isolation" and "mate," reflecting the idea that the player who made the mistake has isolated their king and is in checkmate. The concept of isemate is not recognized by the rules of chess, but it is a common occurrence in casual play and online chess platforms. The mistake typically involves the player who is to move offering a draw, but the other player does not accept it, leading to a situation where the player who offered the draw is in checkmate. Isemate is often used as a humorous or lighthearted term to describe this situation, and it is not considered a valid result in competitive chess.
