It is not quite that simple. First of all, it is not at all sure that everybody gets the same EGTB score regardless of what code and tables they use. The score will depend on whether you use distance to mate or distance to conversion, on whether you consider the 50 move rule, and on whether you have bugs (we are talking about non-trivial code, after all). An even more important point is that EBGT probing in not only about getting the right result, but also about getting the right result *quickly*. It is not at all easy to compress the EGTBs down to a manageable size and still be able to decompress and probe quickly on the fly. In my opinion, including Nalimov's EGTB code in the program is no better (and no worse) than using a GUI book. Tord
