There was an earlier game in the Noteboom somebody -- perhaps you -- posted here, with Rebel 10.0 as white vs. Chess Tiger. The opening was also a Noteboom, and the verdict of the poster of the game was that Chess Tiger simply fell into a bad opening line. I looked at the game, and it was straight out of "Play the Noteboom", by Mark van der Werf and Teun van der Vorm. The game followed Maggeramov - Sherbakov, Moscow 1992 all the way to move 32. From the book: "Black has sufficient compensation for the exchange. The light squares on White's kingside are terribly weak. The first threat is 32...Bh3+ and wins." All the same, Rebel got in f4 and went on to win very shortly thereafter. I was going to take a harder look at the line, because if White is really winning there then Black needs to deviate somewhere earlier... but I've been busy, and haven't gotten around to it yet. >In general, the book handling is still a bit "beta", you could say. >More or less what you would get if you just imported the Rebel book into a Fritz >tree and had Fritz/Junior/Hiarcs/Nimzo/etc. play with it. >I'd even go as far as saying that the very small opening book that came with >prior Tigers is better (just look how Tiger 11.5 plays in SC 99 with its 250 K >book compared to the 11 MB book of 11.8.2). > >But don't worry, I am sure "Rebel Tiger" will have a book that has been checked >"by hand". > >--- >Shep Dave
