Oh, OK. 
Abso-freakin’-lutely. Computers have done for chess what they did for accounting. Human chess players get through games mainly on heuristics. They know not to develop the queen early and not to make too many pawn moves in the opening. They control the center and castle early. But computers have revolutionized that thinking. We now know that you don’t always have to follow the rules precisely, and we get popular lines like theSveshnikov Sicilian that moves a ton of pawns and makes weak squares, yet looks solid. The theory on the Semi-Slav/Botvinnik variation now stretches to 30 moves or more in some lines.
Generally speaking, chess advances when a certain variation is pronounced dead because one side or the other comes up with a move that seems to be a complete refutation of the variation’s core idea, but then someone else finds a refutation of that refutation and all the pros start reexamining the line. It’s very much a “better sword->better armor->better sword” process.
The fact that Kaspy will have the Najdorf as a weapon will turn the match in his favor, no doubt.
I had to look up Najdorf since I’m not well versed on Chess strategy, and according to Wikipedia, Fischer used it.
The OP said “both in their peaks,” implying that it would be an anachronistic match. Given that condition, Weismuller destroys the high school girls.
Of course it’s anachronistic, but I’m not following what you mean by this.
Weismuller’s best time was 4:57 in 1923, the current women’s world record is 3:95.15. You have to remember that they didn’t have goggles, really poor strokes, the pools were shallow and had lots of waves. Put Weismuller in the pool today in his prime and I’m pretty sure he’d go much faster. It’d be like not being able to castle or move the pawn two on the first move for Fischer and allowing Kasparov using them.
If we’re talking the roughly 1994-ish Kasparov against the 1970-ish Fischer, Bobby gets killed. Chess advanced too much, and unlike Fischer, Kasparov didn’t try to learn it all on his own.
I don’t think anyone has ever handled the black side of the Sicilian like Kasparov. Bobby’s insistence on playing e4 would be his doom.
Hmmm. Not sure what you mean, but if Weismuller enjoyed the same advantages as today’s swimmers have, or if today’s swimmers were as deprived as Weismuller..in other words, if they competed with the same conditions…Weismuller would destroy them.
If it were possible for them to fight at their peaks, Ali takes Tyson. Tyson had a great punch, but he failed every gut check he ever faced in the ring. Ali would have given him more than he could handle.
