SO far I have covered gambit lines in e-pawn openings against 1...c5, 1...e5, 1...e6 and 1...c6.
Now it is the turn of the Scandinavian or Centre-Counter Defence: 1.e4 d5.
My recommendation could not be simpler: 2.d4, and hey presto we have the Blackmar-Diemer Gambit.
Play will usually proceed 2...dxe4 3.Nc3 Nf6 4.f3.
Blacks can refuse to take on e4, but we still have gambit lines against 2...e6 (see part four) and 2...c6 (see part five).
This is not the place to go into the intricacies of the BDG, but note that declining it on move four is much rarer than many people think - two out of three games in ChessBase's 2020 Mega database feature acceptance by 4...exf3.
After 5.Nxf3 blacks play 5...Bg4 slightly more than 46% of the time.
The main line continues 6.h3 Bh5 7.g4 Bg6 8.Ne5.

8...e6
This is Black's best response, according to the analysis engines Stockfish12 and Komodo11.01. Black is about to lose the bishop-pair, but there is no reason why he should fall behind in development.
9.Qf3!?
Developing with a threat. Stockfish12 prefers 9.Bg2, which was Tartakower's choice back in 1954 (the first time the position appears in Mega20).
9...c6 10.g5 Bh5?
Black seeks to save the bishop-pair, but this natural-looking move is a mistake. The main line runs 10...Nd5 11.Bd3 Nd7 12.Nxg6 hxg6, which the engines reckon favours White after 13.Nxd5 or 13.0-0.
11.Qf2 Nfd7 12.Be2!
Simple but effective. Black cannot capture on e2 because of the mating threat to f7, so ...
12...Bg6
... or 12...Nxe5 13.Bxh5 Ng6 14.Rf1 with a strong attack.
13.Nxg6 hxg6 14.Rf1 Qb6?
Better is 14...f6 15.gxf6 gxf6 16.Qg3 g5 but White has huge compensation for a pawn.
15.Qxf7+ Kd8 16.Bd2!?
This seems even stronger than capturing the e6 or g6 pawn.
16...c5
Black's queen is trapped after 16...Qxb2!? 17.Rb1 Qxc2? 18.Rf3.
The game finished:
17.dxc5 Bxc5 18.Na4 Qc7 19.0-0-0 Bd6 20.Nc3 a6 21.Qxe6 Re8 22.Qxg6 Nc6 23.Nd5 Qb8 26.Bh5 1-0
