Let's start with how far removed are Xiangqi and OrthoChess. (1)Trim 10x9 board to 8x8 and ignore divisions of river and palace. (2) Enhance Knight to leaping. (3) Enhance Elephant to all-diagonal but never jumping. (4) Replace two weak Guards with one strong Queen. (5) Add 3 Pawns repositioning all to Rank two, with Western way of diagonal capture and one-time two-step. (6) Omit Cannons. (7) Polish off with specialized en passant, castling. /// So, Xiangqi and OrthoChess are arguably roughly only these seven steps apart. If we wildly tolerate margins of 7 Mutators, Xiangqi and Mad Queen are even same game. Edit Form You may not post a new comment, because ItemID ChessboardMath4 does not match any item.
