Rob Hartelt Caro-Kann to BDG

Rob Hartelt wins a Caro-Kann that transposed into the Blackmar-Diemer Gambit. White had a winning plan that led to a crisp sharp victory. White looks to be having fun! Black used the handle “petrorebro” and was listed as being from the Ukraine. The players were ready for action in this one minute game. Rob Hartelt consistently applied pressure. Black lost on time just before getting mated. White still had 35 seconds left.

When I played both the Caro-Kann Defence and Slav Defence as Black, it made sense to answer 1.d4 d5 2.Nc3 with 2...c6. The natural continuation 3.e4 dxe4 lead to positions that I knew well. I wrote about my own adventures in my book on the Caro-Kann.

In this opening typically White plays 4.Nxe4 when Black has a choice between 4…Nf6, 4…Nd7 and 4…Bf5. I played them all from both sides of the board. Once in a while as Black I faced a bold White player who offered a gambit by 4.f3!? exf3 5.Nxf3 Nf6 6.Bc4. Note that White might arrive at the same position after 4.Bc4!? Nf6 5.f3 exf3 6.Nxf3.

Rob Hartelt is an active player in the Colorado chess scene. I’m sure that he picks up tactical ideas being around so many strong players. One such motif was h4 with the bishop sacrifice Bxh7+ followed by Qh5. It proved to be an excellent practical choice at a fast speed. White’s plan worked here with Black’s cooperation.

This BDG Ziegler 6.Bc4 e6 is section 1.9 in Blackmar-Diemer Games 1 and Blackmar-Diemer Theory 3.
