There is a sensible diagonal move on your board, although I can see why you
did you not use it as it is complex. On one level (literally rather than
the usual metaphorically!) the diagonal move is self-evident, along path
constant in colour and also in either letter or number. What a diagonal
move between levels means is determined by observing that the board can be
rotated into five other positions in the same frame (and reflected into
another six), which your noation recognises as they split evenly into your
levels I-VII, red-blue and green-yellow levels 1-7, and red-yellow and
blue-green levels a-g, revealing such diagonals as all the c4 squares.
Temperature goes out of the window (metaphorically rather than the usual
literally!), but is hardly needed once a diagonal capture has been found
for the Pawn.
	As well as this lot the board can be viewed with any corner as a
hexagonal cell at the top and the rest of it as six progressively larger
triangles of such cells down to 28 at the bottom. Each hex level has all
four colours and the diagonal move described in my first paragraph
requires a change of hex level.
