I think Kasparov would have won since he simply was the much stronger player of the two. In one event anything can happen, but Kramnik wouldn't have beaten Kasparov twice, just like Euwe didn't beat Alekhine twice. Kasparov never lost against Kramnik again after the match, by the way, but won against him in Astana 2001, and also won a rapid/blitz match against Kramnik in 2001.
Kasparov vs Kramnik WCC Rematch
Kramnik knew history and Kasparov very well. And don't want a short reign as WC. Kasparov must be very frustrated he did not get a rematch.
Kasparov deliberately decided not to include a rematch clause in the original contract, because he was sure he would win. He was wrong! Tough luck.
Kasparov was probably much too confident looking at Kramnik's weak match results, with bad losses in his three latest Candidates matches, against Kamsky, Gelfand and Shirov, going 1-7 in wins against these players. Kasparov had a career score of 32-1 against the same opponents!
But as soon as he was given the title match instead of Shirov, Kramnik must have realised that this was his chance of a lifetime. He prepared excellently, while Kasparov seemed to be out of shape. And once the match was lost Kasparov could just regret that he had abolished the rematch clause.
There was absolutely nothing to prevent Kasparov from going through the qualifying process and becoming the mandatory challenger. He was the highest rated player in the world, so he had to be the favorite to qualify. But he chose not to.
He didn't want to, but at the same time I think he felt as if he had everything to lose by playing a minimatch knockout qualification arranged by Kramnik, where the winner might get a match a couple of years later. Topalov played in it and had to play 17 days in a row without a single rest day and eventually lost the last minimatch against Leko, who did get a match two years later, where Kramnik was the last World Champion that could give himself draw odds and kept the title that way.
Carlsen was the favourite to win the Candidates in 2011, but also refused to participate. Mainly because FIDE changed the regulations a lot halfway through the cycle so Kramnik and Topalov could be given free spots in the Candidates after refusing to participate in the qualifications together with Carlsen and Aronian, who instead had to participate in a qualification for the right to participate against Kramnik and Topalov. Then too being the best player was less important since the short knockouts usually are won by outsiders. Carlsen wanted a longer match system but FIDE removed the longer Candidates match agreed in the rules, and Carlsen refused to play.
But going back to Kasparov, he did accept to participate in the reunification process by playing a match against the FIDE World Champion Kasimdzhanov to face the winner of Kramnik vs Leko, but the Kasparov vs Kasim match never materialized since FIDE didn't want to pay for the match and it was postponed time and again. Kramnik also claimed that he no longer was bound by the agreement, and said that he might not play the winner of Kasparov-Kasim, which made the latter match even less attractive for sponsors.
Kasparov is coming back!!!!
He is going to play in a tournament with Carlson
"It was like what happaned in the WCC 1972. Fischer was much more prepared than Spassky"
More prepared but also 125 Elo stronger...
I hate to break the news to you people, but Kasparov is just playing in the Blitz/ Rapid section in August. And Carlsen, Anand, and Kramnik aren't going to be in the blitz section.
And to the Kramnik vs Kasparov, Kramnik just bored Kasparov into losing. Which was a smart plan. He knew Kasparov was going to demolish him if they played tactical openings, so he just played the boring Berlin defense.
Kramnik won the WCC from Kasparov in 2000. Kasparov demanded a rematch which Kramnik refused. Who do you think would won if the WCC Rematch was played?
