1.c4 {Notes by Nimzowitsch} 1...e6 2.e4 c5 {Better was 2...d5
3.cxd5 exd5 4.exd5 Nf6} 3.Nc3 Nc6 4.f4 d6 {It is better
4...Nf6} 5.Nf3 g6 6.d4 Bg7 7.dxc5 dxc5 {If 7...Bxc3 8.bxc3
dxc5 9.Qxd8 Kxd8 10.Ne5 with white advantage. And if 9...Nxd8
10.a4 and 11.Be3, comfortably putting pressure on the enemy
queenside.} 8.Qxd8 Kxd8 9.e5 h5 {Black should have played
9...f6, to eliminate the blocking e-pawn. Black's plan to put
a knight in f5 and to establish on the other hand a blockade
is impracticable because a fast white attack does not leave
him time for maneuvers.} 10.Be3 b6 11.O-O-O Ke7 12.Bf2 {All
the diagonal will be occupied with decisive effects.} 12...Nh6
13.Bh4 Kf8 14.Bd3 Bb7 15.Be4 {the decisive effect of this
bishop in the great diagonal is due to the fact that black is
private to oppose a rook in the d-column} 15...Na5 16.Bxb7
Nxb7 17.Rd7 Rb8 18.Rhd1 Kg8 19.Be7 {In order to play Ng5
without blocking the Bishop.} 19...Nf5 20.Ng5 Re8 21.Bf6 Bxf6
22.exf6 Na5 23.Rd8 {Initiating a mating attack} 23...Kf8
