GK: You have to play your openings. It’s nothing against the Queen’s Gambit Declined. It’s very solid. I think that for Hikaru to play the Queen’s Gambit, it requires a lot of patience. Also, it’s the preparation: you have to know all the details, and Magnus has played it with both colors. Of course Magnus can play the King’s Indian, but there’s always a chance to complicate things, to create some counterchances. And even if you go down, you will be kicking and screaming. While here, you know, you will be just screaming.
