11...Bg4!?
This is probably a novelty. The idea is to induce White to play f3, blunting the action of the white light-square bishop. Stockfish15 and Komodo13.02 like 11...a4, albeit giving White a slight edge.
12.f3
The engines reckon this is best, although White could ignore Black's last move and carry on developing with 12.Be3. However then 12...Nd4 seems fine for Black.
12...Be6 13.Be3 f5
The engines still like ...a4.
14.Qd2 Nd4?!
This is probably just weakening.
15.Bxd4?!
White has at least a slight edge, according to the engines, after the natural 15.Nxd4 cxd4 16.Bg5.
15...exd4 16.Nef4 Bf7 17.Nxe7+ Qxe7 18.exf5 gxf5 19.Qf2?!
This does not seem to achieve anything. Probably better is immediately seizing the open file with 19.Rbe1 or 19.Rfe1.
19...c5 20.Rfe1 Qf6 21.Nh3 Rae8 22.f4 Re7?
Now White gets an initiative. Best, according to the engines, is preserving the bishop-pair with 22...h6!?, and if 27.Bxb7 then 27...Re3!? 28.Rxe3 dxe3 29.Qxe3 Re8, eg 30.Qf3 Qd4+ with strong play.
23.Rxe7 Qxe7 24.Re1 Qd7 25.Ng5 Kh8?
Better is 25...Bg6, but White is on top.
26.Nxf7+ Rxf7 27.Re2
Even stronger, according to the engines, is 27.Qe2.
27...Re7 28.Qe1!?
And here the engines prefer 28.Rxe7 Qxe7 29.Kf1.
28...Bf6
Black may have some drawing chances after the engines' 28...Re3!? 29.Rxe3 dxe3 30.Qxa5 Bxb2, although the engines much prefer White.
29.Bd5 Kg7
Again ...Re3!? may be better, but still good for White.

Black is 'only' a pawn down, but f5 needs defending and the white king cannot be prevented from entering the black position. White is completely winning, as will become evident.
The game finished:
32...Bd8 33.Kf2 Kf6 34.Ke2 Kg6 35.Bc8 Kf6 36.Kd2 Bc7 37.Kc2 Bd8 38.Kb3 Bc7 39.Ka4 Bd8 40.Kb5 Kg6 41.Kc6 Be7 42.Kd7 Kf6 43.Bb7 Bf8 44.Bd5 Be7 45.Ke8 1-0
