DrMAL: One of two theoretical duels Kasparov fought as white in very complicated Botvinnik variation (position after 10.Nbd7) featured in My Story video DVD #2 of 5 (other is Kasparov vs Dorfman, 1981). Video is at http://www.youtube.com/watch?v=j1pR... reader is encouraged to watch. Yes, Kasparov talked about how Sveshnikov made the most noise in group of GMs analyzing after, spouting white's attack is wrong, black should win, but he did not play it later in round 16 they had for Soviet Chamionship here.
Biggest debate was on 30...e5 vs. 30...Be5 as noted above, Sveshnikov kept hammering how 30...Be5 wins for black. Here is computer eval proving Kasparov correct, 30...e5 was indeed the better move (but still loses for black). It would have been nice to see Garry silence him finally OTB but Sveshnikov would not back up his oral excrement. Instead, Sveshnikov still used it to recently for early draw J Carstensen vs Sveshnikov, 2011 shame on him.

24.Nxc3 was absolute genius positional sac showing how teenager Garry was already singular, he simply understood chess deeper than anyone else. Computer eval as usual does not give this type of sac enough score it cannot be proven by straightforward combination (hence the name positional sac).

There were several other brilliant moves played by both sides including simple capture 30.Bxa7 leading up to debate.

Game itself was based on Timoshenko's innovation 22...Na5 (position before was known tabiya at that time) where alternative 22...Ne5 was played in Kasparov vs Tal, 1983.
