Done. One point: offsets give you all the attacks, defenders on each square already organised with the *size/value* of the piece in order. working out piece safety and so on is easier with offset data. bitmaps give you all the attacks/defenders, but essentially in random order. bitmaps give you nicely organised piece location data, for pattern maps and stuff. piece safety calculations are done by slower, knowledge intensive programs. thus bitmap design (unless you're also willing to generate attack tables as well) will steer the program(mer) away from this sort of knowledge (within the current framefork of doing things). Enuff said :) Chris Whittington
