Rules for YariShogi (Copyright (c) Christiaan Freeling)

YariShogi is a Shogi variant invented by Christiaan Freeling. It is played on a 9x7 board, with the last three ranks as the promotion zone. YariShogi uses the same rules as shogi, except for the pieces which are used and a few differences noted below.

These are the differences between Shogi and YariShogi:

  1. YariShogi is played on a 9x7 board, with the last three ranks being the promotion zone. This is the opening setup:
    
           7    6    5    4    3    2    1  
        +----+----+----+----+----+----+----+    White (White)
      a |\ R/|\ N/|\ N/|\ K/|\ B/|\ B/|\ R/| a 
        +----+----+----+----+----+----+----+    
      b |    |    |    |    |    |    |    | b 
        +----+----+----+----+----+----+----+
      c |\ P/|\ P/|\ P/|\ P/|\ P/|\ P/|\ P/| c 
        +----+----+----*----*----+----+----+
      d |    |    |    |    |    |    |    | d

      f |    |    |    |    |    |    |    | f 
        +----+----+----*----*----+----+----+
      g |/ P\|/ P\|/ P\|/ P\|/ P\|/ P\|/ P\| g 
        +----+----+----+----+----+----+----+
      h |    |    |    |    |    |    |    | h 
        +----+----+----+----+----+----+----+    
      i |/ R\|/ B\|/ B\|/ K\|/ N\|/ N\|/ R\| i 
        +----+----+----+----+----+----+----+    Black (Black)
           7    6    5    4    3    2    1  
  2. Unlike Shogi, Pawns in YariShogi are allowed to give checkmate when dropped.
