Movement and Capture:

Pieces move 1 space straight or diagonally forward. You may only capture when moving diagonally.

Move Notation

Since there are only three spaces a piece can move to the move notation is simply "[row][col][LFR]", where [LFR] is 'L' for forward-and-left, 'F' for straight forward, and 'R' for forward-and-right. For example, "E2F" means "more the piece at E2 forward 1 space", and "C7R" means "move C7 diagonally forward to the right".

You may also use a "source-destination" notation. For example, "E2-E3" or "C7-B6".
