Needing a win, GM Khachiyan uncharacteristically opens with 1. Nf3 and pretty soon faces a double fianchetto. But the game hinges on control of the d-file and what he calls the "Anti-Nimzowitsch." You'll be amazed at the simplicity with which the GM controls the entire board and stifles those black bishops. His opponent has to resign without even being down any material!
