Sidestep

As played by Nigel Short against Garry Kasparov - 1.d4 d6 2.Nf3 Bg4 is a relatively new system with some high-class adherents. Completely sound, it leads to dynamic and unbalanced middlegames. The defense has the considerable merit of sidestepping standard theory, and is a favorite of Anand and Speelman. GM James Plaskett analyzes Black's best plans against all possible White set-ups.
