1. Use normal chess pieces 2. Use a larger 11x11 board 3. Set up the pieces just like chess in the middle 8x8 of the board 4. The movement of pieces are just like chess, except:

  1 -- there is no castling
  2 -- there is no pawn promotion

5. After a piece is captured, it becomes yours. You can drop a captured piece at any time. Dropping a piece counts as a move and ends your turn. 6. You start off with an extra 8 pawns that you can drop 7. If a piece is surrounded by enemy pieces (forward, backward, left, and right squares occupied by enemy pieces, like in go), it is captured.
