Position after 34.Kg5. Short had marched his castled king up the board, and now 35.Kh6 (if 34...Kh7, then 35.Qxg6+ Kh8 36.Qh6+ Kg8 37.Kf6) followed by Qg7# cannot be stopped.[1]

In chess, a king walk, also known as a king march, steel king, or wandering king (Dutch: wandelkoning, literally "wanderking"), is a maneuver where the king travels a large distance to a different part of the board in the middlegame or opening. During a king walk, the king may travel along its own side of the board (from kingside to queenside, or vice versa) to reach a safer position. Alternatively, it may travel up the board, often involved in a mating attack against the opposing king.[2]

Activating the king before the endgame is a highly unusual occurrence; before the endgame, the safety of the king is considered paramount, and players are recommended to keep it out of harm's way.[3][4] In contrast, Wilhelm Steinitz, often known as the father of modern chess, was renowned for his maxim that "the king is a fighting piece".[5][6] Dutch chess historian and author Tim Krabbé has documented over one hundred such games.[2]

Because of the rarity of such tactics, those that reap rewards for the attacking player often have brilliancy prizes bestowed upon them.[7][8] Perhaps the most famous in recent history,[9] where Nigel Short defeated Jan Timman in Tilburg in 1991, was voted as one of the hundred greatest chess games in a list compiled by master Graham Burgess, and grandmasters John Nunn and John Emms.[10]
