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.
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.
For example, in Diagram 1, White can play 1.Rg3 Ke4 2.Re3+ Kf4 3.Rg3 Qc6+ 4.Kg1 and Black cannot make any progress. (This position would still be a draw even with a Black pawn on g4 or h4.) [ 3 ] However, getting the rook to the correct position can pose significant difficulties. [ 3 ]

Marseillais chess (or Two-move chess): After the first turn of the game by White being a single move, each player moves twice per turn. Monster chess (or Super King): White has the king and four pawns (c2-f2) against the entire black army but may make two successive moves per turn. There is no check. Players win by capturing the king.
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. Zermelo has stated that there are many games of this type; however his theorem has been applied mostly to the game chess.
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.
