How is that true? I'd imagine it's to reduce the search space against human players and to make use of records of games played - a large corpus of which have involved traditional openings. It doesn't seem to imply the acknowledgement claimed?
All of this is not to say that computers have not overtaken humans in chess. They have. But primarily because they have superb qualifications as practical players - they never make crude errors and all humans on occasion do. This trumps all other considerations. But the vast gap you see when comparing the human lists and the computer lists is exaggerated - 500 Elo points means a 95% expectation. I am 100% convinced that if Magnus could be properly motivated (think big $$$ and somehow convincing him that scoring a decent proportion of draws as White would be a "win") he could deliver for humanity :-)
Interesting theory. Personally, I'm not sure it's clear that good strategy can overcome ruthless tactical precision. I'm also not sure a human could ever be motivated to achieve a 0.00% tactical blunder rate. (Much as I would love to see human strategy defeat computer tactics.)
You are 100% wrong. Computers overtook humans at chess in 1995. Unless there is some insight Magnus Carlsen or any other GM has which they are not sharing, it will remain that way.
Another factor is that it is trivial to change the computers repertoire of openings and there are a wide choice of these. Humans including Magnus require weeks to months of preparation before they are ready to play new openings or deviate from prepared lines.
Finally, (and I freely admit that this is my own personal opinion), Magnus Carlsen may not be our best choice of human to play against a computer. There is an unmistakable emotional fragility to him which manifests when he is losing (cf his games with Anand); a good deal of his strength lies mainly in the early middle game and ending but computers are superior in the latter; and he often wins games out of sheer stamina- a strategy that wont work with the silicon beast.
