But then you click on the tab called reference and see that already 90 games have been played and you say to yourself, there must be some logic behind it! Let's leave it, it is all theory! But let us try to understand what is the exact nature of Black's compensation after making White's next move.} 20. cxd3 {The first thing we notice over here is the complete domination of Black on the light squares. The bishop on c6 is excellently placed and has no opponent. The knight on f8 can soon come into the game and has a wonderful square on d5. At the same time White's attacking prospects have vanished and the bishop on d2 lacks scope to some extent because of the e5 pawn. It is true that Bd2 has a nice home on d6 but What exactly will it control from those squares? b8 and f8 squares. Are they even important? So all in all Black has good compensation for an exchange. } Ng6 ({Ths is one of my favourite games.
