Topeltmatt

Topeltmatt is a term used in chess to describe a specific type of checkmate. It occurs when a player is put in check by two different pieces simultaneously, and there is no legal move to escape the check. This can only happen when the king is attacked by two pieces at the same time. A common scenario for a topeltmatt is when a queen and a knight deliver a mating attack. Another possibility is a rook and a bishop, or even two rooks. The key characteristic is that both attacking pieces are delivering the check, and the king cannot block, capture either attacker, or move to a safe square. Topeltmatt is a relatively rare occurrence in chess games, often resulting from complex tactical sequences or a significant material advantage. While it is a decisive checkmate, it doesn't have any special rules or implications beyond the standard rules of checkmate. The term itself is derived from Estonian, where "topelt" means double and "matt" means mate.
