About the Byrne Variation

In the Byrne Variation, Black meets the Main Line 9. Bc4 with 9...a5 instead of the usual 9...Bd7. The pawn gains queenside space and prepares ...a4 against a king castled long. The line is rarely seen. White most often continues 10. O-O-O, and 10. g4 and 10. h4 also appear. The engine prefers 10. a4, which fixes the pawn, and assesses White's position as clearly better.
