Otseqon chess (draft)

Board
Otseqon chess is played on a 9x9 board [NB. this may be increased to 10x10 in the near future] which initially starts out empty. Players start with an army of starting pieces and on their turn may either place a piece or move a piece that is already on the board. Pieces are only allowed to be placed on the closest 3 ranks to the player. Only one pawn can be placed on each file.

 * 9 Pawns
 * 3 Drunk Tigers
 * 2 Generals
 * 2 Charging Bears
 * 2 Lances
 * 1 Grasshopper
 * 1 Rook
 * 1 Bishop
 * 1 Lion

 * 1 King

Promotion
All pieces other than the Knight, King, Lion, Fire Demon, and already promoted pieces may promote when they reach one of the farthest 3 ranks from their starting position.
