Re: The Secret of Chess

Btw., a correspondence GM just left a nice review on the first part on Amazon: https://www.amazon.com/gp/customer-reviews/RHK64MQ15OJL9/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B074M85CVV Thus, my supposition the stronger the reviewer the better the review seems to be true.

Re: The Secret of Chess

But there is one more interesting phenomenon I discovered, namely that top engines tend to use some terms more often than humans, that would concern in particular for some reason outposts, especially more advanced ones, and material imbalances. Why so? To the extent an engine will rely on assessmen...

Re: The Secret of Chess


SF still does not see Bxa4 wins here.
It lacks the necessary deeper knowledge, of course.
If an engine managed to implement all of the concepts in my book, it would certainly get to at least 5000 elos,

Re: The Secret of Chess

Just to mention that the comparison between top engine and human play in the collection is an interesting observation. We all know that top engine games last much longer on average, and the collection will only corroborate that. But there is one more interesting phenomenon I discovered, namely that ...
