Almost all experts agree that game six – the longest game ever played in a World Championship match – was the crucial game of the match. In a complicated middlegame both sides had and missed chances and eventually an endgame was on the board in which Carlsen was trying to win with rook, knight and two connected passed pawns against Black's naked queen.
Nepomniachtchi defended tenaciously but in the end he cracked under the continuous pressure and lost, which apparently also affected his play in the remaining games of the match.
It is an interesting and complicated endgame and many readers asked Karsten how to treat such positions and whether Black had a draw. With best defense Nepomniachtchi could have drawn the game, but in practical play, with limited time on the clock, the endgame was extremely hard to defend.
Karsten and Robert take a close look how both sides played this difficult position to find out when Nepomniachtchi went wrong.
