Grünfeld Exchange: Classical 7.Bc4 is variation 6 of 6 in the Against the King's Indian and Grünfeld course, a advanced opening course for White (ECO D87). It runs 27 moves and begins 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 …. The bishop goes to c4 and the knight to e2, so a pin on the f3 knight is not possible. After ...Bg4 and f3, Black plays ...Na5. White keeps the bishop with Bd3, takes back on d4 and pushes d5 with tempo. In the lesson every move is explained on a board and then drilled; it is free.
