BDG Variations and Master Games

In a recent post I recommended Knut Jarle Hjørnevik's site on BDG variations. Knut Jarle continues to update his site and has recently added a PGN file of a large number of master BDGs for download. That alone is worth another visit.

Here’s a recent BDG by Knut Jarle with his notes.

Hjørnevik,Knut Jarle - Madland,Kristoffer
Rogalandsmesterskapet (1), 14.11.2008

1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 Bf5 



The Tartakower-Gunderam Defence 6.Ne5 e6 7.g4 Nxg4?
 


Based on a calculation error by Kristoffer. He simply overlooked 9.Nf2! [7...Bg6! is probably the best move in this position, but there are also interesting moves like Be4 and Ne4 available!] 8.Nxg4 Qh4+ 9.Nf2 Nc6 10.Bb5 0-0-0 11.Bxc6 bxc6 



12.Be3 [12.Qe2 Rxd4 13.Be3 Rd6 14.Qa6+ was an alternative, but I was afraid that my own king would end up too vulnerable.] 12...c5! 13.Qe2 cxd4 14.Qa6+



14...Kb8 [14...Kd7? 15.0-0-0! should win for White] 15.Qb5+ Kc8 [15...Ka8? 16.Qc6+ Kb8 17.Nb5 Bb4+ 18.c3 Ba5 19.Nxd4 Bb6 20.0-0-0+/-] 16.Qa6+



And we agreed a draw in this position. [The continuation 16.0-0-0 dxe3 (16...dxc3?? 17.Qa6+ Kb8 18.Qxa7+ Kc8 19.Qa8#) 17.Qa6+ is nothing more than a draw.] 1/2-1/2.
