Absolutely a killing move, threatening 16.Rxe7.

Anyway!

By now Black is a rook up, but her king and queen are too heavily targeted.

Black’s position is hopeless.

21…exd5 22.Re1.

Black resigned.

11.cxd6 exd6 12.0-0 Rfe8, and at least Black wins back the pawn.

Winning back the pawn, but the position becomes more static. A more dynamic approach was 11…Nd7!? 12.cxd6 exd6, when Black seems to have sufficient compensation for the pawn, as White is still struggling with her development.

And now 12…a5 seems a valid try, pressing the b3-knight and vacating a6 for the bishop. Black is OK.
