-Next to orthodox Chess (aka FIDE or Mad Queen), XBoard supports many other Chess variants. -This includes the World's major forms of Chess: Chinese, FIDE, Japanese, and Thai Chess. -But also many popular western variants (Suicide Chess, Crazyhouse, Chess960, Gothic/Capablanca Chess, Seirawan Chess). -
--Full support by XBoard means that the latter is fully aware of how all pieces move, and what the winning condition is. -This means the variant can be played with the option Test Legality switched on, -and that it can accurately check any result claims that engines make. -Non-supported variants can often be played with legality checking switched off. -Then any of the 22 piece types known by XBoard can be used in ways XBoard does not expect. -The only real drawback of this is that the game notation looks a bit crummy, -with many spurious or missing disambiguators, check and checkmate symbols. -XBoard will always be able to read suh games back, however (as on reading it suffers from the same misconceptions on piece movement). -This can be kept baerable by choosing XBoard supported pieces to represent the unsupported ones that -move as similar as possible. -
--Some variants are only partially supported. -This means they have to be played with legality checking off, -although XBoard knows they exist, and even implements some of their rules that no other variant would allow. -For instance, in Berolina Chess Pawns move diagonally, and in any other variant this would lead to disappearence -of other Pawns during the game, as normally XBoard interprets a diagonal Pawn move to an empty square as e.p. capture. -
--The following list tries to group all variants by properties. -Some duplicates occur when a variant fits in more than one group. -
