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.

Rainer Buhmann-Ruud Janssen Germany Bundesliga 2015 Does 10.h4 make sense when Black replies 10…0-0?
Yes! White just marches with the h-pawn to activate the h1-rook.
A) 11…Nxh5 12.Rxh5 gxh5 13.Ng5 f5 14.Ne6 Qe7 15.Nxf8 Qxf8 wins back material and leaves White slightly better;
B) 11…gxh5 12.Nh4; or 12.e3, yielding a big positional plus;
C) 11…Qe7 12.hxg6 fxg6!? 13.e3 ♗xf1 14.♔xf1 ♘bd7?! 15.♘g5, and White had the initiative in Wagner-Pavlovic, Berlin Wch rapid 2015.

Undermining White’s stronghold on e5, opening up the diagonal for the dark-squared bishop, while the g-file may prove useful as well on occasion. What more do you want from one move?
