King's Indian: Some Preliminary Statistics

King's Indian Statistics

The following statistics were pulled from small subsets of the ChessBase Mega 2010 and Corr 2009 databases.  These statistics will be refined by specific variations and moves as the research into the KI goes forward. 

The two sets of statistics can generally be described as:
Mega 2010:  World class players doing state of the art research in advance of the game.
Corr 2009:  Skilled players using good software and hardware for every move.

Conclusions to be drawn are limited from the below numbers, but here's what I think can be made of them:
  • White does slightly better than average against the King's Indian. 
  • The Classical Variation scores solidly OTB, but only averagely in CC.
  • The SämischVariation scores above average in both OTB and CC, but the CC sample is small.
  • The Four Pawns Attack is held in low regard at top levels and the statistics support that.
