I do not buy the claim that humans have better evaluation of pawn structure. It may be even the opposite because computers never forget that some pawn is isolated pawn in their evaluation of some position in the tree when it never can happen to a computer. I do not think that you can use the knowledge of the world champions to say what is the knowledge of humans relative to computers. There are a lot more humans than chess programs so it is not fair to compare the best humans with the best computers. It is more fair to compare humans that are better than 99.9% of the humans with computers that are better than 99.9% of the computers. Uri
