The Most Important Novelty of Informant 105, testposition?

Post by Eelco de Groot »

From a column in Chesscafé about the novelty of the year which was awarded to the game L. Domingues Perez - A. Morozevich from Wijk aan Zee. Any engines out there that stick to the best move? Apparently it has to be found on positonal grounds only, Stockfish 1.6.3s likes 13. gxf6 too and only very deeply calculating decides that there is probably no more than a total draw in that. Then it finds 13. Na4 again after about 20 hours. I suppose gxf6 is not so bad at some point it also gets a good score.

It is probably not so easy to say what you should evaluate better to just play Na4, I have no idea myself because the variations after gxf6 at one point became very different from each other, I have not seen many common traits there.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

and i don't suppose you could share where you unearthed this hidden gem?

shredder 12's analysis seems quite thorough, but it has found no move better than Na4 yet.
