Notes by I. Gunsberg.

1. 3.exd5 This old-fashioned continuation is after all safest, as it leaves White the initiative of the first move, and he can proceed in a quiet way; whereas in the more showy continuation of 3. Q Kt to B 3, Black has often been known to obtain a dangerous preponderance on the Queen's side.
2. 5…Bd6 We prefer B to K 2 for the second player in every opening where it is impossible to play B to Q B 4.
3. 7.Be3 The Bishop is not strongly posted on K 3.
4. 7…Bg4 As a rule it is not good to pin the King's Knight, unless one is assured of the co-operation of the Queen's Knight either on K 4 or Q 5. If Black, however, had played P to B 3 and Q to B 2, then there would have been some object in pinning the King's Knight.
5. 10.Qc2 White proceeds in the usual manner of development, but his game would be all the better if B to K 3 had not been played. It is strange that so many players should neglect the favourable opportunity which they have in this opening of converting the game into Queen's side play by resorting to P to Q Kt 3 and P to B 4, instead of playing P to B 3 and Q to B 2.
6. 13…Ne4 This is a distinct gain for Black, and the direct result of the move of B to K 3, without which it would not only have been impossible for Black to plant his Knight on K 5, but it would perhaps have been feasible for White to play Kt to K 5.
7. 16…g5 Black vigorously utilises the gain of time to develop an incisive attack.
8. 22.Nf3 White breaks down under the pressure of attack. Black was threatening Kt to R 4, and Kt to Kt 6, mate. If White had played 22. P to K Kt 4, Kt x P; 23. P x Kt, Q to Kt 6, wins. Or if 22. P to Kt 4, Kt x P; 23. K to Kt 2, Kt x P, wins.
