How Much is that King's Indian Dark Square Bishop Worth?
How do you quantify compensation?
Following on from my blog post (https://www.chess.com/blog/blohmoremoney/analysing-my-own-games-when-you-cant-find-a-plan), GM Bojkov helped review my game. He highlighted to me that my play with White showed how dangerous it is to exchange White's dark squared Bishop for the gain of a pawn, leaving no counterpart to fight the Black dark squared Bishop.
This loss was a great lesson to me, for now I can see how Black dominated the dark squares.
