zydeco: A very creative game by both players.
Larsen plays a bit unorthodoxly in the opening: ...Bd7 and ....Bc6. 10.h4 and 12.Rh3 brings the rook to a good square and gives white good attacking prospects.
Both players saw 14.b4. Larsen says that he didn't think Unzicker would play it: "I was a little afraid of this, but weakening his own position in that way is not Unzicker's style." Unzicker calls his move, 14.Bb5 (with the idea 14....Bxb5 15.f4 Qh5 16.g4,) a "spectacular move," but says he probably could have crashed through with 14.b4 f5 15.f4 Qf6 16.exf5 Qxf5 17.g4 Qxg4 18.b5 Bd7 19.Nd5!
14....Rg8, 19....Qb4, 21....Rb8, and 28....a5 are 'only moves.'
Larsen explains 16....a6 somewhat whimsically by saying: "Nd5 was one of white's potential threats, so black wants to have that square protected by two pawns!"
19.g4! is a cool idea. If 19....Rxg4 20.Ne4!
