1.d4 d5 2.Bf4 e6 3.e3 Bd6 4.Bg3 b6!?
ChessBase's 2024 Mega database has 10 more-popular moves: ...Nd7, ...Nc6, ...c6, ...h5, ...Qc7, ...c5, ...f5, ...Bxg3, ...Ne7 and especially ...Nf6. However, many lines will transpose.
5.c3 Nf6
Keeping the option of ...Ba6, to exchange light-square bishops, as well as the mainstream ...Bb7.
6.Nd2 0-0 7.Ngf3 Bb7
7...Ba6 has been played by grandmasters, but after 8.Bxa6 Nxa6 9.Qe2 White has an edge, according to Stockfish16 and Komodo14.1.
8.Bd3 Ne4 9.Bxd6 cxd6!?
 |
| Black has greater central control and a useful half-open c file, but White has the better bishop |

10.Qc2 f5
Another pawn on a light square, but ...f4 is in the air.

| White's next move never crossed my mind |

11.Ke2?!
Is the king really safe here? There are lots of obstructing pawns and pieces in the centre, but the centre is certainly not closed.
11...Nc6
 |
| White's next move also did not cross my mind, although it probably should have done, and it is consistent with Ke2 |

12.Rag1?!
I was expecting the white rooks to be centralised, followed by the king dropping back to f1. The text is more aggressive, but almost certainly too slow.

14.Ne1?
The engines suggest 14.Nb3, but agree Black is winning, although they do not agree on how to proceed (suggestions include ...a5, ...Qe8, ...Qf6 and ...f4).
14...exd4 15.Bxe4
Both pawn recaptures are met by ...Nxd4+.
15...dxe4
Possibly even stronger is 15...fxe4, but from now on Black's advantage is so large that winning continuations are more-or-less a matter of taste.
16.Qb3+ Kh8 17.cxd4?!
Probably a little better is 18.exd4.
There now comes an extended king hunt.
17...Ba6+ 18.Kd1 Na5 19.Qa2 Qc7 20.Qb1 Nc4 21.Qc2 Qd7 22.Qb3 Bb5 23.Qa2 Nxd2!? 24.Kxd2 Qc6 25.Qb1 Qc4 26.Qd1 f4 27.f3

27...fxe3+
Missing 27...Qxd4+! 28.exd4 e3#.
28.Kxe3 exf3 29.Nxf3 Rce8+ 30.Kf2 Re2+ 31.Kg3 Qc7 32.Qb1 Qf4+ 0-1
