Notes by C. von Bardeleben.

1. 3.e5 This line of play leads to an interesting game, but is not so sound as 3. Q Kt to B 3.
2. 5.f4 At this juncture the only good move is 5. Kt to B 3, recommended by the late German master, Louis Paulsen. After 5. P to K B 4, Black gets a great advantage of position.
3. 5…cxd4 This is not the best way to take advantage of White's weak fifth move. Black should have played 5.... Q to Kt 3; 6. Kt to B 3, B to Q 2 (!) (this move must be made at once to prevent 7. B to Q 3, because it is Black's intention to bring his King's Knight to K B 4, and thus to attack the White Queen's Pawn); 7. B to K 2, Kt to R 3; 8. P x P, B x P; 9. P to Q Kt 4, B to B 7, ch; 10. K to B sq, B to K 6; or, 8. Castles, P x P; 9. P x P, Kt x Q P (!); 10. Kt x Kt, Kt to B 4, with an excellent game.
4. 7…Nh6 Better would be B to Q 2, in order to prevent 8. B to Q 3.
5. 16.g4 This move looks very dangerous, but is good enough if correctly continued.
6. 16…Nc2 This sacrifice is of very doubtful value; preferable would be Kt to R 3.
7. 24.b4 Here White misses a good opportunity of getting a violent attack. If he played 24. P to B 5, whereupon Black has probably no better answer than P x P, upon which follows, 25. Q x P, ch, K to B sq; 26. P to K 6, with an excellent game. (See diagram.)
8. 29.Rf3 If 29. P x P, then P to Kt 5 (!), and the Black Queen's Knight's Pawn cannot be taken off because of 30.... R to B 8, ch.
9. 29…axb4 A brilliant combination, which turns the game in favour of Black by sacrificing the Queen.
10. 33…Kc6 Black manoeuvres very cleverly with his King; compare the 36th and 38th move of Black.
11. 40…b3 White can do nothing else, anything is indifferent; for instance, 41. K to B 6, and then follows P to Kt 7; 42. Q to Q sq, ch, R to B 7; 43. Q to Q 4, ch, K to Kt 6; 44. Q to Q 3, ch, K to K 7; or 42. Q to R 2, R to Kt 5; 43. Q to Kt sq, K to Kt 4 (threatening P to R 7); 44. Q to Q 3, ch, R (B 3) to B 5, and Black wins.
