    It suddenly occured to me that engine book authors assume that your engine is going to slug it out in tactical skirmishes in the Sicilian. Here's what happened to my poor engine playing versus the French. How can I edit this line so that its more favourable to the engine?

    Why don't you just stop playing useless engine matches?

    They are not useless, the Sicilian games are of a high quality and can show you what can happen in standard theory. As I only play a few human games, I watch the engines responses to standard openings.

    The top engines are usually the ones where the strong human has edited the opening book to play to that engines style.

    On the human side I plan to become a rook before Christmas. What's your status on the server?

    Bishop - which means the same rank as you have right now. I plan to become a top GM by Christmas.

    I've drawn a lot vs. the French in there. It's funny because I've seen my book go up to 50 moves deep in the Sicilian and 5 in the French.

    Imagine an engine vs human GM event for $1m and the human found such holes in the engines book? This is like Kasparov's famous 1. e3 see the article

    50 move book = waste of time.

    I would have thought the exchange variation would be best for engines. It avoids most of positionally nuanced play that is present in a lot of other french variations.

    No, the exchange variation scores pretty badly for engines too.

    I really can't see how a perfectly symmetrical position with initiative can be bad for white ... drawish perhaps, but not bad

    .. of course this comes from someone who last had experience with the french roughly a decade ago so perhaps it does play out badly in practise

    What white should have done is go for 12. Bd3 rather than the 12. a3 which is an error. There are GM games such as Short-Korchnoi so that is probably an oversight from the book author.
