Kasparov-Karpov[Subject Thread] [Add Response]

GK-AK_1985. The first notice is that they are not trading pieces like Spassky and Fischer. In the Kasparov-Karpov world championship game above, all pieces are on board through Move 20.

Upon 28 d6 g4, Black is already down a Pawn, and could take the d6-Pawn but instead wants to cover two en passant squares at once. '33 Rf4 Ne4' and there are only 7 moves left to the score, whilst 6 pieces of each 7 are still on board. Again the peculiar line-up is preventing even trading and leads to fast wild finish all over at the Move 40.

Exactly '33 Rf4...' is the White move that does not do anything but cause exchanges leaving the two White Knights too far away. But where does White go wrong? Just earlier with '31 fxg4...' served better with 31 'f4...'. Then White is apace with Black though still expect eccentric finish with more pieces than pawns.

GK-AK_1985 -- In this game between Karpov and Kasparov their first championship 1985, White is already in trouble when with 33 ...Ne4, Black declines to take Rook for Knight. One solution is suggested 31 f4..., but really that is the wrong Pawn to be moving. Instead just earlier, '30 h4...' right after the Black King waiting move will give White King a safety square and let the White Bishop exit soon. Karpov is panicky over two Rook open files of Black and now Queen training most of the way down a third file, but '30 f3...' on that Queen file is where White goes wrong.

Karpov was world chess champion 1975-1985.
Http://www.chessvariants.org/index/displaycomment.php?commentid=29431,
there is a game, the first to consider, in the 1985 Karpov-Kasparov match,
but Karpov has better move sequence from Move 30 on, as noted where White goes wrong.
The spectacular finish requires that mistake '30 ...f3' actually done, but White can take the game in a different direction, not ending at Move 40, with 30 ...g4.

Http://www.chessgames.com/perl/chessgame?gid=1067175.  Really at Move 30
what other move does White have? There is worrisome pressure at f2 and need to act. '30 h4...' instead ot the chosen 30 f3 forces Black decision whether to use the en passant. King gets the safety step away from either White Rook crossing the board. It's a whole changed line-up and this game, come to be called Brisbane Bombshell, will not end at any Move 50 let alone actual Move 40 after improved 30 h4...

Http://www.chessgames.com/perl/chessgame?gid=1067179 -- it's the
forty-two-mover that makes the all-time top-ten list, not the forty-mover
already having been posted here, that was played in the same world championship match. Let's see what we can do with this above, the last
game of the match, making Kasparov champion -- probably just repeating the
business about the prescient Rook move. Http://www.chessvariants.org/index/displaycomment.php?commentid=29329. The '23 ...Re7' just looks like a good move, and no variantist is going to memorize whether any ''move 23'' with any opening (with any given rules-set) is a novelty or not. 
Credit Garry Kasporov a dramatic finish needing all 24 scheduled games. 
The first 23, Karpov had won 3 and Kasparov 4, and if Anatoli Karpov wins the above Game 24, the resulting tie 12-12 means champion Karpov retains the title.  Not to be, Black wins above. Now at Move 29 White is up a Pawn. Where does White go wrong?

White-Karpov needs a Win to stay champion,
http://www.chessgames.com/perl/chessgame?gid=1067179, so picking off the Pawn Move 28 looks good. Hereabouts is where White goes wrong. Instead '29 Bf3...', the other Bishop, and there should be no annoying 29 ...Nh5.  That light Bishop in the real full score is on the same g2 to the bitter end in defeat, and this Move 29 can bring the piece into play towards Win. Not to retreat the dark Bishop, moving it twice in a row, is the risk to try for a win. Between the two moves, one supports the f4-Pawn about to be attacked, and the improvement attacks the h5 where Black Knight would try to launch. 
___________________________ (One relevant computational minutia: at this point White pieces and pawns attack central sixteen squares about 24 times to Black's only 13 times. Black pieces cum pawns are peripherally distributed, or blocked, and White can indeed win from this critical juncture up and down a move or two of Move 30 -- preventing Kasparov from having become new champion.)
