Masonic shogi

Masonic shogi is a shogi variant invented by George R. Dekle Sr. in 1987. The game is played on a modified shogi board whereby alternating are indented to the right—resembling masonry brickwork. The moves of pieces are adapted to the new geometry; in other respects the game is the same as shogi.
Masonic shogi was included in "World Game Review" No. 10 edited by Michael Keller.
Board characteristics.
Indentation of alternating ranks results in "cants" (oblique files) approximately 30 degrees from the vertical and "diagonals" approximately 30 degrees from the horizontal, the same as hexagon-based chessboards when cell vertices face the players. (For example, rooks have six directions of movement. Masonic bishops, however, are limited to the four diagonal directions to the sides.)
Game rules.
All normal shogi rules apply, including initial setup (see diagram), drops, promotion, and so on. The pieces, however, have specially defined moves.
Piece moves.
The diagrams show how the unpromoted pieces move. As in shogi, a "dragon king" (promoted rook) moves as a rook or as a king. A "dragon horse" (promoted bishop) moves as a bishop or a king.
