The chess position you see in the picture below was played at the Internet Chess Club or ICC. Bonglee from Saudi Arabia, who was playing with the White pieces, had spent considerable tempi advancing his Knight to the e6 square in the heart of Black’s position.
As you can see the e6 horse is attacking the Black rook at g7. After rook to e7 attacking the White Steed, things look OK for the second player because the outpost for the White Knight is under assault.
After cxd5, Black will probably play Na6 threatening Nb4 which attacks the naked pawn supporting the White horse. Positional players frequently are willing to spend considerable time maneuvering their knights to advanced outposts,but often at the neglect of the rest of their chess pieces. This allows their opponents time to generate counter play which can weaken the advanced outpost.
