Grunfeld Exchange 8.Rb1-TWIC 955

The Grunfeld 8.Rb1 exchange variation is a deep bed of theory. The Be5-c5(idea ...Ba5) is recommended in The Safest Grunfeld(Chess Stars 2011) but with 15...Ba5.

GM Maze tried a new idea-15...c4, but the pawn sacrifice was poorly followed up which turned it into a nice gift and a straight forward white win.

White is well on the way to realizing the P+ advantage but the Bd7 stands in the way as a firm blockader. What should white do now?

Queen’s Indian 4.a3 Ba6-TWIC 950 2013

TWIC 950
The 4...Ba6 line is an active plan where a typical plan is a central dark square blockade, for example here after 18...Nf4.


The feature game shows a nice plan for combating black's buildup using a queenside attack.
