I am quite lucky lately as several of my over-the-board opponents are accepting my Blackmar Diemer gambits lately. So did my opponent last sunday in the Belgian teamcontest.
Guido De Bouver - Yves Cornille
1.d4 c6 2.e4 d5 3.Nc3 dxe5 4.f3 exf3 5.Nxf3 Nf6 6.Bc4 e6
But what should white do now ? The bishop on c4 is rather misplaced and actually belongs on d3.
7.Bg5 Be7 8.00 00 9.Qe1 Nbd7 10.Bd3
Pointing the bishop back onto h7.
10...Re8 11.Qh4 Nf8 12.Ne5 Qc7
A fatal mistake.
13...Kxf7 14.Qh5+ g6 15.Qh6 Qd8 16.Ne4 Qxd4+ 17.Kh1 e5
Desperately trying to make some escape room.
18.Nxf6 Bxf6 19.Rxf6+ Kg8 20.Bxg6 !!
Interesting to note is that in the same match ( a team in the Belgiam competition consists of 8 players ), my teammember and friend also got a Blackmar-Diemer, also sacrificed on f7, and also won.
Thomas Schurins - Oleg Knyazkov
1.e4 d5 2.d4 e6 3.Nc3 dxe4 4.f3 exf3 5.Nxf3 Nf6 6.Bc4 Be7 7.00 00 8.Qd3 Nbd7 9.Bf4 a6 10.a4 c5
11...exd5 12.Nxd5 Nxd5 13.Qxd5 Nf6 14.Qxd8 Rxd8 15.Rae1 Bf8 16.Ng5 Nd5?? 17.Nxf7
So two Blackmar-Diemer sacrifices on f7 in one single team contest - talking about an interesting day !
