Chess variant played on a cross-shaped board. Each player starts from two sides of the four.
Otherwise the rules of chess apply, with the following differences:
- There are two pawn directions on each side. The pawns always move to the opposite side of the board.
- Pawns promote on one of the final four squares of they path. If a pawn gets on a side-branch by capturing, then it stops as a pawn at the end, and cannot promote unless it gets back to the main direction by capturing again.
- There is no castling.
