I dunno why they call it chessmaster 10th edition cause its actually the 11th edition, as i show all the previous editions: 2000,2100,3000,4000,5000,5500,6000,7000,8000,9000,10th
as you see, its actually the 11th edition.
another thing is that chessmaster must make a multiprocessor edition to stay in the market and be competitive because professionals would probably use the deep series from fritz cause it works well with core duo and it gives them, a more difficult oponent. When will chessmaster multiprocessor edition come out?
