10.Qe3!
QUESTION: Why the queen move? Castling looks more normal. ANSWER: With the text, White increases his control over the e5-square and prevents Black from playing the freeing move ...e6-e5. Instead, after 10.0-0-0 e5 11.Qe3 exd4 12.Rxd4 Nc5 13.Rf4 Qh6 Black had no problems in K.Shirazi-M. Quinteros, Jakarta 1978.
10...c5 11.0-0-0 b6 12.Bb5!+/-
Once Black can put his bishop on b7 he will equalize. 12.Bb5 prevents this as 12...a6 13.Bxd7 Bxd7 14.dxc5 wins a pawn.

9.g4!
ANSWER: This is the point of 8 Bxf6. White gets in g4-g5 a move quicker. That said, although White was successful in this game, I do not recommend this plan at all.
9...b5 10.g5 Nd7 11.Nxf4 cxd4 12.Ncxd5 exd5 13.Qxd5 Ra7 14.Bh3 with a complicated game.
