From Alexei Shirov's book, Fire on Board, in the intro to the game Shirov-Thorhallsson: "This game introduces a novelty which should probably be called the "Shabalov-Shirov Gambit", as suggested by Mikhail Krasenkov. As I remember, 'Shaba' expressed the idea first, although it occurred to us almost simultaneously while we were listening to pop music and lazily moving the pieces around."
