He was playing it in 1970 in serious games, http://www.chessgames.com/perl/chessgame?gid=1044307 and his first class career ended after 1973 WC match. Not really clear if ever gave it up.
Fischer And The KIA
Sort:
Thanks. I played through that quite quickly. I like the way that the attack was switched from flank to flank. Interesting how the opening was played against a Caro Kann when current 'wisdom' is that only e6 defence systems afford white the best chances. Having been looking at the KIA again, I just wonder if this is because the French formation afford the most aesthetic kingside attacks that make the anthologies, whereas queenside play tends to be less of the 'white to play and win' variety.

Personally I think that the KIA is still able to be played ambitiously against the French, CK, and Sicilian. Definitely a nice sideline to know for certain situations as a 1.e4 player.

Today KIA is not considered so good.Black's play has been improved too much.
Even in the classical French line with White launching an all out attack on k-side , new plans have greatly improved Black's play.
Wesley So recently won an interesting game.
I think Black is dead lost after the unlucky 21...c4, and anyway white can play in this line Fischer's move 13.a3 bxa3 14.bxa3 and now Miagmarsuren played against Bobby 14...Na5?! which is very slow- today it is known that Black has a good game with either 14...Ba6 or 14...Rb8.

Niklis and Aagard's "Playing the french" does a pretty good job explaining black's possibilities in this line, including analysing Fischer's games with 13a3. Also "e3 poison" pretty much proposes the same line for white against the Kings Indian. Still an worthwhile structure to look at. Think unless have looked at line carefully the side with attack is still easier to play.
Yes, that 'e3 Poison' looks interesting. The interlocking of the two pawn fronts creates a different dynamic depending on whether the pawn is on e3(or e6 for black). There is a game I played through where Fischer has black against a a timid e3 player (via Reti English formation) and plays the Kings Indian Attack. Normally we associate the player of black and Fischer as playing the Kings Indian Defence.
The e5 (or e4) pawn (KIA) wedge seems to demand more of a piece orientated assault than when a pawn change become interlocked than with the more common KID kingside assaults. I notice that in the KIA centres, there may be greater fluidity and less locking (?)
Good post.. thanks...

The "e3 posion" line is literally reverse kings indian attack with extra Rf-d1, for example this Grischuk game

I recall Andrew Martin gives a game arising from 1b4 or perhaps from a Colle type move order on a video of his leading to the KIA reversed. These systems where white tries and plays as black are frustrating for the second player, sometimes without being satisfyingly incisive for the first player who chooses them. Although the older I get the more fun it is to prevent the attacking impulses of the younger players 
Anyone know why Fischer finally gave up the Kings Indian Attack? Specific games that changed his opinion you may know of? I recall he says something like he used to think it was the best line against e6 Sicilians.
