Kasparov Plays a Blackmar-Diemer Gambit (sorta)

My previous post mentioned a line in the Trompowsky Attack that can transpose into a (near) Blackmar-Diemer Gambit. That got me to thinking about this line, so I took a look at such games that might have been played since I last examined it years ago. This little goody turned up. I never thought I'd find a game where Kasparov played a BDG, even if it was in a simul, even if it was only an "enhanced" BDG—that is, a transposition that gives White a move up over the normal BDG. But here it is:

Kasparov,Garry (2817) - Carneiro,Marco Paulo
Sao Paulo 450th anniversary  simultaneous
Sao Paulo, 21.08.2004
Trompowsky to BDG Teichmann Defense [A45]

1.d4 Nf6 2.Bg5 Ne4 3.Bf4 d5 4.f3 Nf6 5.e4 dxe4 6.Nc3 exf3 7.Nxf3 Bg4

The Teichmann Defense to the BDG, but with the Bishop developed to f4 representing the extra tempo gained in the transposition from the Trompowsky.

8.h3 Bxf3 9.Qxf3 c6 10.0-0-0 e6 11.Bc4

11...Nbd7?

11...Be7 would blunt the forthcoming 12.d5

12.d5 cxd5 13.Nxd5

13...Nxd5

13...exd5 is better: 14.Rhe1+ Be7 15.Bxd5 0-0 16.Bxb7 Bc5=

14.Bxd5

14...a5??

14...exd5 is still better: 15.Rhe1+ Be7 16.Bd6+- and play might go 16...Ne5 17.Bxe5 0-0 18.Rxd5 Bg5+ 19.Kb1 Qb6 20.Bxg7 Rae8 (20...Rfe8 21.Rf1; 20...Kxg7 21.Rxg5+) 21.Red1]

15.Bxb7 Ra7 16.Rxd7 Qf6 17.Rhd1 Be7 18.Rxe7+ Qxe7 19.Qc6+ Kf8 20.Bd6 g6 21.Bxe7+ Kxe7 22.Qc5+ Kf6 23.Qxa7 Rf8 24.Qd4+ e5 25.Qd6+ Kg7 26.Qxe5+ Kg8 27.Qf6 h5 28.Bd5 Kh7 29.Bxf7 1-0.
