Notes by C. von Bardeleben.

1. 4.Bd3 A dull continuation. I prefer the usual moves 4. B to Kt 5, or 4. P to K 5.
2. 4…c5 The right answer.
3. 5…exd5 I believe that still better would be B P x P; the game might proceed then in the following way:—6. B to Kt 5, ch, B to Q 2; 7. Q x P (!) (if 7. P x P (?) then B x B; 8. Kt x B, Q to R 4, ch, or 8. P x P, ch, K x P; 9. Kt x B, Q to R 4, ch, winning a Piece), B x B; 8. Kt x B, P to Q R 3 (!); 9. Kt to Q B 3, Kt to B 3; or, 7. B x B, ch, Q x B; 8. Q x P, Kt to B 3, and Black has in both cases the better development.
4. 11.Qf4 The attack introduced by this and the following move is not sound. White should have played 11. Q R to Q sq.
5. 13.Rad1 At this juncture 13. P to Q B 3 was absolutely necessary to prevent the following move of Black.
6. 15…gxf6 Very well played. Black, after having exchanged the hostile King's Bishop, runs the risk of weakening his Pawns on the King's side to obtain thus attacking prospects.
7. 18.Qh6 This square is very unfavourable for the Queen. Better would be 10. Q x Q.
8. 21…Rg7 Of course not Q x P, because of 22. Kt to Kt 6, ch, winning the Queen.
9. 23.Rc1 This proves to be fatal at once, but the White game is no longer to be saved (see diagram). If, for instance, 23. Q to R 5, then, R x P; 24. P to R 4, Q x P; 25. R to K B sq, Q to K 6, ch; 26. K to R sq, R to Kt sq; or, 25. Q to K 8, ch (?), R to Kt sq; 26. Q x B, K R x P, ch (!); 27. Kt x R, Q to B 7, ch; 28. K to R sq, Q x Kt, mate. If White defends the Queen's Knight's Pawn with 23. R to Kt sq, Black answers Q to Kt 3.
10. 24.Qh5 He should have played 24. Kt to B 3, but only to prolong the struggle. Black has played the attack very cleverly.
