Found a $4.00 copy of an old, Dover, games collection book from the Second Piatigorsky Cup held in 1966 in Santa Monica, CA.
http://www.amazon.com/s/ref=nb_ss_gw?url=search-alias%3Daps&field-keywords=secon... 10 participants:
Fischer, Petrosian (world champion at the time), Spassky, Larsen, Najdorf,
Reshevsky, Portisch, Ivkov, Unzicker, Donner
18 rounds @ 5 games = 90 games annotated by the participants, sometimes both players on each game.
21 out of the 90 games were King's Indian/King's Fianchetto games.
( including 6 games with Fischer playing black )
( along with 13 Nimzo-Indians, 12 Sicilians, and 12 Ruy Lopez games for all your classic opening needs ! ! ! )
Great tool for:
1. Studying vintage KID technique through champion-GM-level annotations.
2. Studying the ebb/flow of a high-quality, ten player, round robin tournament, eventually won by Spassky as he held off a charging Fischer.
3. Improving your descriptive notation reading skills.
I have both Piatigorsky books (they were reprinted in paperback by Dover) and enjoyed them.
Of course the Bronstein/Vainstein book on Zurich '53 is also a good source for King's Indians, and Najdorf's book on the same tournament (in Spanish) is an even better read IMHO.
Which brings me nicely on to "Miguel Najdorf: King of the King's Indian Defense" by Minev - a useful collection, illustrating the nitty-gritty of playing the KID; even the games where Black suffers can be instructive.
Finally, for another good selection of classic annotated King's Indian, Marovic's book from 1984 Play the King's Indian is hard to beat..
