Jeremy, to drop a White-owned tile (displayed with a white border), use the piece designation '$' and for a Black-owned tile (displayed with a black border), '%'. So in your example, the move would be $-d3. This would drop a White-owned tile on the d3 space. The idea is that the board only exists for ranks 1, 2, 7, and 8 at the start of the game. Players have to add tiles, which they own, in order to create a legal place for their pieces to move to. So in your example, White would add a tile to d3 in order to say move a Pawn to d3 later. A player can also remove their own tiles. So, White could later remove the tile using '-d3'. I hope this helps. Take a look at the below example of the first few moves. Note that each player drops their own tiles upon leaving a square, since they own those tiles. Thanks for your kind offer to help with a new preset or graphics.
