1.e4 {Notes by Lasker.} e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d3 Bc5 5.Nc3
d6 6.Be3 Bb6 7.h3 Be6 8.O-O {A mistake. The idea to retake at
c4 with the Pawn is good enough in itself. After the exchange
at c4, White's doubled pawn, even though isolated, would do no
harm, on account of its central position; it would hamper
Black's pieces and could not be easily attacked. But it was a
condition, sine quo non, to secure the Queen Knight against
Ba5 by say a3, for the trebled Pawn on the c-file has no
mobility whatever.} Bxc4 9.dxc4 Ba5 10.Nd5 {After 10.Qd3 Bxc3
11.bxc3 b6, the c-pawns would be fixed, and White's game
should be lost in consequence. Hence White plays va banque for
attack.} Nxe4 11.Qd3 f5 12.c3 {12.b4 Nxb4 13.Nxb4 Bxb4 14.Qd5
or 12.b4 Bxb4 13.Rb1 was more in the nature of a va banque
attack.} O-O 13.Rad1 Bb6 14.b4 Bxe3 15.Nxe3 Qf6 16.Rfe1 Ng5
