If you are going to buy a chess program, and really want the best, you must of course act methodically. One way is to study the rating lists, but then remember that the rating lists chiefly are based on matches between the chess programs and that no rating list is complete. Not even the list of SSDF (the Swedish Chess Computer Association) is complete, which also means that Eric Hallsworth´s list, which is based on the list of SSDF, neither is complete. You can also study the results from different chess computer tournaments - see Tournaments chess programs. Furthermore you can read reviews and analyses of chess programs - see Chess software reviews .
