Military chess, also known as blind chess, was invented by a South African man named Henry Michael Temple in 1899. He himself is a chess lover. Because his partner wanted to play a game reflecting war, he borrowed pieces and invented the war game. Kriegspiel's English explanation is WAR GAME. It is a variant of chess, and it is also a real game enjoyed by the public (a real ornamental sport! )。 It allows onlookers and chess players to share joy. Military chess is a successful variant. The biggest difference between it and chess is that it is not allowed to look at each other's pieces, which is more challenging. The birth of military chess immediately swept the world. This also produced some military chess experts (Bob Thimel, Ike Thayer and Rhea B Hayes) and won the city championship. It can be seen that there have been military chess competitions abroad for a long time. I wonder if there is such a competition in China.
