Blackmar-Diemer Gambit 5...c5

This Blackmar-Diemer Gambit would normally arise after 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 c5. Here "anon4" played yet another unrated blitz game against IM Michael Mulyar. White treated the position as if it was a BDG Bogoljubow 5...g6. The mysterious "anon4" pressed the attack and eventually busted through on the f-file for checkmate.

Blackmar-Diemer Blind Sheldrick

Kevin Sheldrick won a Blackmar-Diemer Gambit from the Caro-Kann Defence 4.Bc4 line Heinrich von Hennig played in 1920 and 1929. The games continued 4...Nf6 5.f3 exf3 6.Nxf3 e6 7.0-0 Be7 a few years before Diemer to invented the BDG! Kevin wrote:
"Hi Tim!
The following is a short BDG game that I played on the internet using my blindfolded account, though I wouldn't be surprised if you already had a game with the same moves in your collection somewhere. Blindfold play can be tricky to keep track of but it can be made easier to do if the game is not too long. I have to admit that I started off with the evil 1. e4 move, but then we transposed back into BDG territory, so I guess it counts!? Bye, K. Sheldrick"
Thanks, Kevin. From your 11.Qd3+ [1-0. Rathmann-Meyer, corr 1970] I played a 2008 game vs Anaconda that ended 11...Ne4 12.Qxe4+ Kf6 13.Qe6 mate 1-0.

Sheldrick (1959) - NN (1917), Blindfold lichess 2019 begins 1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Bc4 [called the von Hennig Gambit] 4...Bf5 5.f3 exf3 6.Nxf3 Nf6 7.0-0 Nbd7?? 8.Bxf7+! Kxf7 9.Ng5+ Kg6? [better is the defeatist 9...Kg8 10.Rxf5+-] 10.Rxf5!
10...Kxf5 [after 10...e6, White has many wins, perhaps the simplest being 11.Nxe6 Qe7 12.Qd3!+-] 11.Qd3+ Kg4 12.Qh3 mate 1-0 [Notes by Sheldrick]

London System 2.Bf4 Hansen

Chris Hansen wins with the London System 2.Bf4. He writes: "Hi Tim! Thought I might forward this short London to you. I continue to have fun with the London in Blitz (mostly 3 min). Here, Black missed the 'standard' Nf8 defense. I read somewhere that no mate with Nf8...certainly true here...game is near level following Nf8!. Best Regards, Chris"

Hansen (1897) - Guest (1764), Friendly 3 Minute Game, 25.05.2019 begins 1.d4 d5 2.Bf4 e6 3.Nf3 c5 4.e3 cxd4 5.exd4 Nc6 6.c3 Bd6 7.Bg3 Bxg3 8.hxg3 h6 [8...Nf6=] 9.Bd3 Nf6 10.Nbd2 0-0 11.Qe2 Re8 12.Ne5 Nxe5 13.dxe5 Nd7 14.f4 Qc7 [14...Nc5=] 15.0-0-0 [15.g4+/-] 15...f6 16.Bg6 [16.Qh5!+- looks strong.] 16...Re7 17.Nf3 fxe5 18.fxe5 b6 [18...b5 19.Rdf1+/=] 19.Kb1 a5 20.Rh5 [Another way to attack is 20.g4+/-] 20...Ba6 21.Qd2 b5 22.Rdh1 b4 [Hansen suggested 22...Nf8 although Black is still in deep trouble after 23.Qg5!+-]
