The first of three Chess programs I ended up with in time for this review: interesting to see them all together. According to its own publicity, Boss is supposed to be the best chess program around: but unless you are at a very good level yourself, you won't notice much difference in quality of play between these programs.

With Boss, you get a slightly squashed chessboard, which is no trouble after a few minutes play; the graphics are clear and the moves very easy to make. You can't change the colours of the screen and pieces, but you can set the screen with POKE 36879 before loading and your chosen screen colour remains in operation whilst the program is running.

Major playing difference - Boss takes en passant automatically whilst Grand Master only does this if told to. But only a fussy chess player will find the slight variations each of these programs plays on the rules in any way annoying.

So this is a good basic chess program with its nine skill levels. The explanatory notes could do with a bit more detail, though.
