Actually I’ve heard this opinion before: I recall someone (Schroeder ?) having said that positional knowledge is worth only about another ply or two of search depth. That may be true for winning against other software, but not for the use of software as a sort of chess instructor substitute. Having a superb positional playing software, I believe, (even if it is not among the top SSDF few) is more valuable for instructional purposes since it would be plenty adequate for tactical instruction but yet provide one with lots of examples of good positional play that a non-master needs to see in a variety of positions. Good tactics can be seen and studied in a ton of books, CDs, etc, but (non-trivial) maximal positional moves are not as readily to be seen. Regards, George
