With everything else being equal (using two computers with equal CPU) the chess program with a solid Opening Book NOT (an Opening Book created by Players of chess strength of < less than 2600)should perform at least 30 rating points higher than the same program without an Opening Book. Now if the Opening Book was created by games from average players < less than 2300 than today's top programs should perform better without an Opening Book. My reasoning behind this is that no top programs without an Opening Book should loose any match against any player rated < less than 2300. Pichard
