I took a look at this article, and it seems like total BS. First, it opens by saying that it's a review of the "best commercially available programs." Then it IMMEDIATELY heads into a long ANTI-CRAFTY portion, when we all know that Crafty is free for the download!!!! That says something about the author and his qualifications. The author DOES SAY that Crafty is often included as an engine with commercial programs, but even so....Why in the world would you BEGIN AN ARTICLE DEVOTED TO A REVIEW OF COMMERCIAL PROGRMS with a review of one of their SUBSIDIARY ENGINES. You wouldn't. He goes on to present a tournament he designed to determine the strength of Crafty ("To compare Crafty with the others..."), ostensibly to provide objective support for his observation that "Crafty is extremely strong in tactics, but it makes positional errors and misplays some endgames. It doesn’t understand piece mobility. Despite its high rating on the Internet, Crafty is a weak program compared with the best commercial chess programs." The tournament shows Crafty getting 2.5 points of 10 against Nimzo, Fritz, and the like. But since Crafty is free for the download, and since it's a BONUS ENGINE, why does he NEED to design a tournament explicitly to evaluate Crafty? Hint for the author: "Sir, you should not head directly into a tangent after explicitly stating the theme of your article." This is UTTERLY STUPID, because it seems to make Crafty the primary focus of an article entitled "Commercial Chess Programs: A Comparison." Worse, later he goes on to IGNORE HIS OWN RESULTS by presenting the outcome of another tournament he made for fun in which Crafty participated, at the same time controls. Here are the results, taken from the webpage: ChessBase home competition. Swiss style 7 rounds, 12 players. Automatic tournament 30 minutes per player per game; 1 Junior 5 x ½ 1 1 1 1 1 1 6½ 2 Crafty 16.6 ½ x 0 1 ½ ½ 1 1 4½ 3 Junior 4.6 0 1 x 0 1 ½ 1 1 4½ 4 Fritz 6 0 0 1 x ½ 1 1 1 4½ 5 Nimzo 7.32 0 ½ 0 ½ X 1 1 1 4 6 Hiarcs 7.32 ½ ½ 0 x ½ ½ 1 1 4 7 Hiarcs 4 0 0 ½ x 0 1 0 1 2½ 8 Hiarcs 6 0 ½ 1 x 0 0 ½ ½ 2½ 9 Fritz 5 0 0 0 0 1 x 1 ½ 2½ 10 Fritz 5.32 0 0 0 1 0 x ½ 1 2½ 11 Comet B09 0 0 0 1 ½ ½ x 0 2 12 LG2000 0 0 0 ½ ½ 0 1 x 2 These data DIRECTLY REFUTE his earlier conclusion that "Despite its high rating on the Internet, Crafty is a weak program compared with the best commercial chess programs." In these data, it ties Fritz 6, and beats Nimzo 7.32, and Hiarcs 7.32, and Fritz 5.32. He then acknowledges that "The only reliable ranking is that of the so-called Swedish rating list," but neglects to mention that Crafty places higher in his little tournament than Hiarcs 7.32 and Fritz 5.32, former list champions. Arguments about the relative strength of various programs could go on forever, of course, but based on the DATA THE AUTHOR ARGUES FROM, he is cannot exactly be called bright.
