Xodul

This game is a variant of chess inspired by international chess, shogi, and xiangqi. The differences from chess are:

1. the board is 8x9, where the startup position contains the traditional pieces at left hand-side and the additional pieces at right hand-side;
2. various additional pieces were introduced:
   • a wizard piece which can teleport or move two squares diagonally
   • a guard piece which moves one square orthogonally or various squares along its row/column in the direction of the king up to the maximum of intercepting the coordinates of the king
   • a lance piece which can move any number of squares forward or diagonally one space
   • a cannon piece which is the same as its counterpart in xiangqi (note: the chess rook was replaced by a xiangqi car, which has the same movement)
3. pawns can be promoted by replacing it with a captured piece;
4. pawns are promoted to generals upon reaching the last line, which moves one square to the front or diagonally.
