Exchange Variation: Classical 7.Bc4 is variation 1 of 6 in the Grünfeld Defence course, a advanced opening course for Black (ECO D87). It runs 26 moves and begins 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 …. White builds the c3-d4-e4 centre and develops with Bc4, Ne2 and Be3. Black attacks d4 with ...c5, ...Nc6 and ...Bg4, drives the c4 bishop away with ...Na5 and fights for d5. In the lesson every move is explained on a board and then drilled; it is free.
