Tigrey

Tigrey can be thought of either as a further expansion of Expanded Chess, or as a combination of Expanded Chess and Tiger Chess. It is played on a board of 144 squares, with each player having 36 pieces.

Setup

Pieces

The Pawn, Knight, Bishop, Rook, King, and Queen all have their standard moves, including the Pawn's double step and en passant capture. Other pieces are described below.

The Gryphon makes a diagonal step and may then slide outward as a Rook.	The Osprey leaps two squares straight and may then slide outward as a Bishop.
The Ski-Rook leaps two squares straight and may then continue sliding in the same direction as a Rook.	The Ski-Bishop leaps two squares diagonally and may then continue sliding in the same direction as a Bishop.
The Pegasus makes a 2,1 leap, like a Knight, and may then slide in the longer direction of the leap as a Rook.	The Astrologer makes a 3,1 leap, like a Camel, and may then slide in the same direction as a Bishop.
The Zebra makes a 3,2 leap.	The Tiger makes a 3,2 leap, and may then slide in the same direction as a Bishop.

Rules

Unless otherwise mentioned, the rules are as in Chess.

Castling and King's Leap

The King has two special moves, but may only make one of them in any particular game. Either move can only be made if the King has not moved yet and is not currently in check.

1. The King may castle by sliding three squares in either direction and moving the corresponding Rook to the last square passed over by the King, as long as none of the squares the King passes through are attacked by an enemy piece and the Rook hasn't moved yet.
2. The King may leap up to 3 squares to either of his first two ranks.

Promotion

Pawns may promote on any of the last four ranks. Each rank presents different options for promotion.

9. On the 9th rank, a Pawn may promote to a Knight, Zebra, Ski-Bishop, Bishop, Astrologer, or Osprey.
10. On the 10th rank, a Pawn may promote to a Ski-Rook, Rook, or Tiger.
11. On the 11th rank, a Pawn may promote to a Gryphon, or a Pegasus.
12. If a Pawn reaches the 12th rank, it must promote to a Queen.

Draw Rule

Because of the large board, the 50 move rule of Chess is changed to a 100 move rule.
