The moves are almost equal in value (and maintain equality according to the engine), but I'm more worried about White's attacking possibilities with the queens on than I am optimistic about my own chances to generate counterplay. There's the further issue that Van Foreest has prepared all of this, so Black is less likely to stumble into some horrible tactical trap prepared with the computer when the queens are off. Finally, I assume that Giri must have been well behind on the clock by this point, which is another reason to get the queens off and simplify the position. That these factors didn't dissuade Giri is testament to both his self-confidence and his ambition, and people who dismiss Giri as some sort of draw-lover are at best not paying attention. As things turned out, Giri was rewarded in the tournament (and overall, in his career) for his self-confidence and ambition. In this particular game, however, I think it was a misjudgment. The position was very difficult to play, and he was soon lost.}) 20. c5 $1 {Clearing c4 for the bishop and cutting Black's queen off from the kingside, meaning that she won't easily be able to help once White's attack gets going.} b6 (20...
