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.

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 ...
