BDG Huebsch Fleischmann Be3

Andre Fleischmann sent me the follow Blackmar-Diemer Huebsch Gambit. The line resembles the regular BDG, but in the Huebsch, Black takes on e4 with the knight instead of the pawn. Andre Fleischmann played 5.Be3 which strengthens d4 and prepares to castle queenside. His opponent appears to be GM Erik Blomqvist. I assume this was a blitz game since it seems unlikely a grandmaster would lose a classical game like this.

Fleischmann - Blomquist, Germany 03.08.2018 begins 1.d4 Nf6 2.Nc3 d5 3.e4 Nxe4 4.Nxe4 dxe4 5.Be3 e6 6.f3 Bd7 7.Qd2 Bc6 8.0-0-0 exf3 9.Nxf3 Bxf3 10.gxf3 c6 11.c4 Nd7 12.d5 cxd5 13.cxd5 e5

Blackmar-Diemer Gambit Penullar

I have analyzed Blackmar-Diemer Gambit games by Peter McGerald Penullar for many years. His opponent was higher rated but made three serious mistakes. Black neglected to complete queenside development; he weakened the kingside by combining ...e6 with ...g6; and he missed counterplay with 8...c5 or 11...f5. And White also missed something. Chess engines would see 14.Rxf7+! due to the knight fork on the king and queen, but we humans miss stuff. Penullar took advantage of tactical opportunities and forced mate.

Penullar (1855) - nickus89 (2015), Live Chess Chess.com, 29.03.2019 begins 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 e6 6.Bd3 Be7 7.0-0 0-0 8.Kh1!?

London System Counter Attack

London System 2.Bf4 works well for White. What if Black follows suit and plays ...Bf5 as well? Both players attack queenside. White turned to the kingside only to be outplayed in an unbalanced battle in the game Antoaneta Stefanova vs Anna Muzychuk.

Stefanova (2490) - Muzychuk (2564), WCh Women Khanty-Mansiysk RUS, 11.11.2018 begins 1.d4 d5 2.Bf4 Nf6 3.e3 Bf5 4.c4 e6 5.Nc3 Bb4 6.Qb3 Nc6 7.a3 Bxc3+ 8.bxc3 Na5 9.Qa4+ [9.Qb4 Nxc4 10.Bxc4 dxc4 11.Qxc4 Qd5!=] 9...c6 10.c5 b5 [10...0-0=/+] 11.Qd1 Ne4 12.Rc1 g5! 13.Bg3 h5 14.f3 Nxg3 15.hxg3 Nc4 16.Bxc4 [16.g4 Bg6=/+] 16...bxc4 17.g4 Bd3 18.gxh5 Rb8 19.Qd2 Qa5 20.e4 f6 [20...Qxa3!? 21.Qxg5 Rb2 22.Qe5 Rg8-/+] 21.e5 Qxa3 22.exf6 Rb2 23.Qxg5?
