   256 color modes are definitely faster than the 16 color planar modes.  I
converted my 640*480*16 sprite engine to run in 640*480*256 on my Tseng ET-

   On storing a chess board - sure you could come up with a clever scheme to
store a board position in the fewest possible bits - but memory is pretty
inexpensive these days, and mass storage too!  Take a few hundred bytes if
need be and store it in the way that allows the code accessing the info to
run as fast as possible...
