What Is A Cross-Check In Chess?

A cross-check happens in chess when a player gets out of kiểm tra and delivers a kiểm tra to tát the opponent simultaneously. Cross-checks usually occur when a piece blocks a kiểm tra and attacks the opponent's king at the same time or reveals a discovered kiểm tra.

GM Daniel Yanofsky vs. GM Harry Golombek, 1951. The Black queen blocks White's kiểm tra and attacks the white king, and the white knight defends its monarch while checking Black again.

Why Is The Cross-Check Important?

Although rare, cross-checks are important because they can help a player to tát take the initiative. This feature proves to tát be crucial in some endgames, such as the relatively common queen and pawn versus queen endgame.

An encounter between GM Mikhail Botvinnik and IM Nikolay Minev in 1954 is an excellent example of how cross-checks can help in this type of endgame. Botvinnik was a pawn up, but Minev would be able to tát draw the game if he could either take the pawn or force a threefold-repetition.

Black tried to tát draw the game by repetition.

This battle lasted for more than vãn 30 moves until the following position arose. Botvinnik's king was in kiểm tra, and he had to tát decide how to tát get out of it.

White wins the game with a cross-check.
White used the concept of cross-checking to tát kết thúc the game on the next move.

White took this opportunity to tát make a king move that uses the concept of cross-checking to tát kết thúc the game. Botvinnik played 91.Kc5, and Black resigned since there is no way to tát keep checking White's king and stop the g7-pawn's promotion.
