Brianking.info mentions Knight 64, with some rules. The second rule "Two Knights of different colour" mystifies me. Bishops of different colour, I can understand, but Knights? They change colour after each move, don't they?

I guess it's meant that the knights are on different colours during setup - but then it still is not clear to me. Is it 2 knights each? Or does black have to place his/her knight on a different colour as white? If the latter, white has an advantage (the same advantage black has in Knight Fight because (s)he can place the knight on the same colour white did).

But regardless, I think white has a (small) advantage of going first. As I can distill from the rules, it's not always that black has as many moves as white - if the game ends because black cannot move, white will have had one more move. Furthermore, even if white and black will have had an even number of moves, on whites turn, there will be more numbers on the board than on blacks turn, which in the long run will give white an edge (because he has had more choices). The advantage is small, but still there.

I wonder, could the advantage be balanced by giving black 0.5 points at the start (meaning that if black and white collect the same number of points, black wins)?
