A variant first described by Claude Shannon provides an argument about the game-theoretic value of chess: he proposes allowing the move of “pass”. In this variant, it is provable with a strategy stealing argument that the first player has at least a draw thus: if the first player has a winning move in the initial position, let him play it, else pass.
A solved game is a game whose outcome (win, lose or draw) can be correctly predicted from any position, assuming that both players play perfectly.This concept is usually applied to abstract strategy games, and especially to games with full information and no element of chance; solving such a game may use combinatorial game theory or computer assistance.
Because it has only four pieces, queen versus rook was one of the first endings to be solved by endgame tablebases. [1] Just after the ending was fully analysed by computers, a challenge was issued to Grandmaster Walter Browne in 1978, where Browne would have the queen in a difficult position, defended by Belle using the queen versus rook ...

Losing chess [a] is one of the most popular chess variants. [1] [2] The objective of each player is to lose all of their pieces or be stalemated, that is, a misère version. In some variations, a player may also win by checkmating or by being checkmated. Losing chess was weakly solved in 2016 by Mark Watkins as a win for White, beginning with 1.e3.
Zermelo's theorem can be applied to all finite-stage two-player games with complete information and alternating moves. The game must satisfy the following criteria: there are two players in the game; the game is of perfect information; the board game is finite; the two players can take alternate turns; and there is no chance element present.
In chess, there is a consensus among players and theorists that the player who makes the first move has an inherent advantage, albeit not one large enough to win with perfect play. This has been the consensus since at least 1889, when the first World Chess Champion, Wilhelm Steinitz, addressed the issue, although chess has not been solved.
The TikTok "towel challenge" has puzzle-lovers baffled. But at least it looks like a ton of fun. The towel challenge requires two people to hold interlocked towels and then try to maneuver ...
