Community variant
UnbihexiumFan Evil Chess 4
A variant with a 8x8 board, wazirs in the back rank, and three major pieces: queens, archbishops, and chancellors. Wazirs move one step horizontally or vertically, archbishops move like bishops or horseys, and chancellors move like rooks or horseys. Wazirs are represented the same way as rooks due to technical limitations, but don't get them confused!
This is a user-catalogued casual variant. Technical details such as board size, FEN, pieces, and hand rules are defined in the Fairy-Stockfish variants.ini block below.
