I don't think it matters at all and I chose that >representation so that I could "visualize" the board easier. I don't think it matters either, but I'm writing a little tool to help me create and manipulate bitboards so I can point and click to turn squares, ranks, files, and diagonals "on" or "off" and quickly get it's hex or decimal equivalent for use in my program. I figured there are others who use different bit representations than I. I suppose some might even use the top 4 bytes for white squares and the bottom for black squares to make bishops more efficient on 32-bit machines, although that might make rotated bitboards awkward. Anyway, I just thought I'd ask before I took the extra time to make this tool configurable so others could use it if they desired. Now's the time to submit your feature requests! :) Russell
