To open is to develop

1.d4 Nf6 2.g4

When the opponent is expecting the Blackmar–Diemer Gambit, it's sometimes good to give him something else to think about. The Gibbins–Weidenhagen Gambit is a good surprise weapon.

2...Nxg4 3.e4 Nf6 4.e5

4...Ng8

4...Nd5 is naturally better.

5.Nc3 d6 6.Nf3 dxe5 7.Nxe5 Nf6 8.Bc4 e6 9.Rg1 c5 10.Be3

Rybka likes 10.dxc5, but having a lead in development, I want to make that lead even bigger, so I continue developing the rest of my pieces.

10...a6

11.Qf3 Qb6 12.O-O-O

This is what I call development: White has developed five pieces in the last five moves. As a result, White has developed all his seven pieces whereas Black has developed only two. As a compensation for that, Black has only one pawn! White has clear advantage (+1.3), says Rybka.

12...cxd4 13.Bxd4

13.Ne4! would have been crushing.

13...Qc7 14.Bb3 Bd7?

14...Bd6 15.Nc4 is better, but White is still winning. After the text, Rybka's assessment is about +5.0.

15.Ne4 Nxe4 16.Qxf7+ Kd8

17.Bb6 Qxb6 18.Rxd7+ Kc8 19.Qe8+ 1-0
