I like it!
The idea of use a 10x10 board is very nice and the array of the pieces is
very ellegant.
I just have a few questions:
How did you got this piece/board ratio?
You said that the optimum number would be 25, why not use 26 (perhaps with
camels or knightriders), instead of 24, or a 2 cell piece (wich I'm still
thinking if it's really worth)?
