I Don't Know Butchy Instead...

For the person that has been grabbed by an opening trap, central in the Fried Liver, the Traxler, or the Poisoned Pawn version of the Najdorf, it doesn't matter how good you are, or what your principles are, Some things you know, and some you don't. That is one of the reasons to study openings.

In the last World Chess Championship, held in Amsterdam earlier this month, the ultimate game came down to previous world champion Shredder vs relatively new kid on the block Rybka. Rybka won. But it didn't need to be Rybka really, it could have been any ol' thing that could have used an opening book. Because Rybka was in a line that it had booked out through it is said 40 moves!! Shredder had fallen out of book around move 12. And it all came down to move 23 where blacks f pawn takes the apparently offered knight. This has been played apparently once before by grandmasters who took the pawn. All the engines will take the pawn. But the book writer for Rybka, and apparently a bunch of guys that play Freestyle chess have spent a lot of time evaluating the line, because it had previously been unclear. But the phrase that was the most telling was by the writer of the opening book, fxe4 loses by force.

I mean, holy cow. This is in the middle of one of the most technical, most ambitious of opening response to e4 by black. And an opening book, knowing what super-grandmaster strength engines will play, led shredder down a path of doom, where every engine, including Rybka, would lose the game by force.

For your amusement...
