Blackmar-Diemer vs Checharov

The International Master with the handle “Checharov” has faced the Blackmar-Diemer Gambit on the Internet Chess Club at least three times. In each game I saw, he declined the gambit pawn. In these games each time Checharov pushed an e-pawn on move four. All three games ended in quick White victories against experienced BDG blitz players.

Here is a summary of his chosen methods.
In 2012 vs Zilbermints, he played 4.f3 e3 5.Bxe3 Bf5 (good).
In 2013 vs Ashkeef, he played 4.f3 e5 (this is bad for Black).
In 2016 vs Zilbermints, he played 4.f3 e3 5.Bxe3 g6 (good).

In all these lines, White attacks without being down material. If Black wants to win, he does best to take the gambit and try to keep it either with 4.f3 Bf5 or even better with 4.f3 exf3. The day this game was played Lev Zilbermints sent me this message: “Hello. Check my latest crush of an IM.”
“Which one?” I asked.
“On ICC. Checharov.” Lev added.
“Okay, thanks. I’ll use it.” I said.

Usually against any …g6 defence, White is hoping to open up the h-file and attack. Here Black did not castle. Instead Chechrov kept his rook on h8 and opened up the h-file. That strategy did not work well tactically.

Zilbermints (2091) - Checharov (2111), ICC 5 0 Internet Chess Club, 26.05.2016 begins 1.d4 Nf6 2.f3 d5 3.e4 dxe4 4.Nc3 e3 5.Bxe3 g6 6.Qd2 Bg7 7.0-0-0 h5 [Black usually plays 7...0-0 when White has the choice between 8.h4+/=  and 8.Bh6+/=] 8.Bc4 Bf5 [8...Nbd7 9.Nge2 Nb6 10.Bb3+/=] 9.Nge2 h4?!

  1. Oops, I meant 10. g4, well, actually, g4 is always a good move - even on move one ;)

  2. Yes, 10.g4 looks good. Of course 1.g4 is exciting in its own way.
