In your hands you are holding the work of the most successful German chess programmer of all time: Shredder 12 by Stefan Meyer Kahlen. No other chess program has won so many world championship titles. The new edition of Shredder is stronger than all previous versions. Meyer Kahlen: “The improvements are visible all over the place. Especially the search and the evaluation have become much more precise. The engine is 100 Elo points stronger than the predecessor Shredder 11.”

I bought Deep Shredder 10 last month. It's the version of Shredder for multi- and dual-core processors. It's the strongest thing I've ever played or analyzed with, although I hear Rybka 2.1 may be even stronger. Deep Shredder 10 consistently beats Fritz 7 in engine-vs-engine matches by about a 2 to 1 margin.
The opening book is pretty good, except that there's a lot of garbage in there played by terrible players. I mean players who hang pieces on move 3 or 4. Also, several of the moves have question marks on them, even simple recaptures and moves that are the only legal moves!
The database has over a million games, but about 50,000 of them could have been thrown out and replaced with decent games. There are some games between Class Z players, yet the entire Kasparov-Deep Blue match of 1997 is missing! Maybe the weak players like seeing their games listed next to those of the immortals, but these are mostly games that should be an embarrassment to anyone. I enjoy an awful game now and then as much as the next guy, but enough is enough! The best of both worlds would have been to keep the bad games and add a few hundred thousand good games. No big deal, though; bigger and better databases are available for free online.
I didn't buy Shredder for the opening book (which, I am happy to say, allows unlimited move adding), the database, or even the "joy" of having an opponent humiliate me game after game. Shredder is superb in all those respects, but I got what I wanted: a super-strong engine to help me analyze and annotate games, both my own and others. I got more than my money's worth.
