1. d4 d5 2. e4 dxe4 3. Nc3 Nf6 4. f3 exf3 5. Nxf3 Bg4 6. h3 Bh5 {Decision time
for Black – retain the bishop or capture on f3 – either line being very
playable and popular when it comes to bog standard defence in a BDG, but both
needing good basic knowledge of what is required on opting to keep a key
defender on the b1/h7 diagonal or immediately trading on the king’s knight.} 7.
g4 Bg6 8. Ne5 Nbd7 {After following the main line of this Teichmann Defence
religiously Black takes an early opportunity to challenge the e5-knight rather
than continue with 8…e6 and the general principle for White in such
circumstances is to remove the white-squared bishop. However, another BDG rule
of thumb is to strive for quick and superior development so, already behind in
that department, the next thematic queen move has to take precedence.} 9. Qf3
c6 {9…Nxe5? 10.dxe5 Nd7 11.e6! wins the knight because of the threat of 12
Bb5+ if it moves and 12 Qxb7 threatening 13 Bb5+ should 11…Ne5 or 11…Nb8
be played. Black could (and probably would) try 11…fxe6, but after 12 Qxb7
his position is shot to pieces.} 10. Nxg6 hxg6 11. Bc4 $5 e6 {11…Qb6!? is an
interesting alternative and White must be prepared to let the d-pawn go as
follows:- 12.Bb3 (12.g5? Qxd4 13.Bb3 Qh4+! leaves the white king searching for
a safe haven.) 12…Qxd4 13.Be3 Qd6 14.g5 Ne5 15.Qe2 Nfd7 16.Ne4 Qb4+ 17.Bd2
Qb6 18.0-0-0 e6 19.Bf4 and despite a two-pawn deficit White has good
compensation, Stockfish evaluating the position as level} 12. O-O $6 {Missing
the potency of 12…Qb6! played a move later and with the white king now
placed on the same diagonal, thereby allowing a crucial check that
significantly improves the previous line. More precise was 12 Rf1 maintaining
the pressure down the f-file without putting the king in the firing line.
Fortunately for Brian his opponent is sufficiently distracted by the threat of
13.g5 to deploy his queen in a purely defensive role.} Qe7 $2 13. Bf4 $5 Nb6 {
13…0-0-0?? 14.Qxc6+! bxc6 15.Ba6mate was a typical BDG trap just waiting to
be sprung!} 14. Bb3 Nbd5 15. Bxd5 Nxd5 16. Nxd5 cxd5 17. c4 $5 Qd7 $6 {Even
though Black remains that gambit pawn ahead and offering an exchange of queens
in a BDG is never thought of as anything other than a good idea, here it is
tantamount to issuing an open invitation to attack an exposed king at a time
when all your minor pieces are still at home and Brian duly takes full
advantage. Fortune favoured the braver 17…dxc4 when White would have had to
have gone all-in with 18.b3!? cxb3 19.Rac1 placing his faith in a rook on the
7th rank. Of course Black can keep pawn-grabbing and then, as the following
analysis shows, what appears to be a lap of the gods type of game somewhat
surprisingly ends in equality:- 19…bxa2 20.Rc7 Qb4 21.Rxb7 Qc4 (21…Qxd4+
22.Be3 a1Q 23.Qxf7+ Kd8 24.Qc7+=) 22.Rc7 Qd5 23.Qxd5 exd5 24.Re1+ Kd8 25.Rxf7
Ba3 26.Rb7 Re8 27.Ra1 Re2 28.Kf1 Rc2 29.Rxg7 Rac8 30.Re1 Be7 31.Rgxe7 a1Q 32.
Re8+ Kd7 33.R8e7+ Kd8=} 18. cxd5 Qxd5 19. Qxd5 exd5 20. Rac1 $1 Rxh3 $2 {…
but Black cannot resist.} 21. Kg2 Rd3 22. Rfe1+ Kd8 23. Rc7 f6 24. Rf7 $1 {
Ignoring the b-pawn in pursuit of mate.} Bb4 $4 {24…Bb4?? and on making this
move Black realised it was about to be delivered (25.Bc7+ Kc8 26.Re8 mate) and
resigned. 1-0} 1-0
