Thanks. This indicates that the game you found may have been in Kramnik's match preparation. Maybe he asked his seconds something like "Find me all kinds of (side-)variants with an early exchange of the queens." This would seem reasonable to me, since this is the most important anticomputer effect of his "Berlin Wall" strategy with black against Kasparov. They could have tested it with retail versions of the Fritz books, how likely it is that Fritz goes into that variants (the match book can't be too much different IMO). It looks now, that not only the Ruy Lopez is dangerous for Fritz in that respect, but probably many other openings too, unfortunately... If it should happen that the book has such a big impact to the match result (in favour of Kramnik), I'm afraid this will be a problem to explain to a wider public. I mean, that the A.I. algorithms so to speak are only partially responsible. It could turn out that the Man vs. Machine comparison (of this parcticular match at least) will be a bit devalued because of that book moves/early queens exchange issue. (But there are still 5 games to go.) Regards, M.Scheidl
