Generals' Chess

I tried to incorporate a piece that moves as a "crooked bishop", but I called it a "general" instead.

Setup

Pieces

General is otherwise known as boyscout or crooked bishop. It moves in a series of diagonal steps, alternating one space at a time between the two diagonal directions that do not move it back toward its origin. Its powers of movement in any general direction resemble a double helix wrapping around a single rank or file.

The Blacksmith is a divergent piece. Without capturing, it can move 1 step orthogonally straight forwards or backwards, or move as a Rook horizontally. They can't jump. To capture, it may move 1 space in any diagonal direction.

Rules

Rules same as in orthodox chess, except:

• Pawns only ever move 1 step at a time.
• Free castling. King and rook can't have other pieces in between them.
• The game is played on a 9x9 checkered board instead of an 8x8 board.
• Each player has 3 blacksmiths beside the board when the game starts. The first move consists of placing all 3 blacksmiths on the player's second rank.
• The generals (known as boyscout in other variants) move like crooked bishops.
• Pawns and blacksmiths promote to generals, rooks or knights (option is open every promotion). This happens on the player's eighth rank.
