Notes by C. von Bardeleben.

1. 10…Qf5 This move is better than Q to Q 4, for the latter move would be followed by 11. B to Kt 5 (!), and if P to B 3 (?); 12. B x P.
2. 12…Kd7 This is somewhat dangerous. Black ought to have played Q to R 4; 13. B to R 4, Q to R 4; of course he cannot play 12.... P x B because of 13. Kt to Q 6, ch, winning the Queen.
3. 20…Bxc4 This sacrifice leads to a clear draw. If White prepared the advance of the Queen's Bishop's Pawn by 20. P to Kt 3, he would have a good attack; the continuation might be then P to Q Kt 4; 21. R to Q B sq, R to Q sq; 22. P to Q B 4, P x P; 23. P x P, P to Q B 4; 24. P to Q 5, B to B 4; 25. R (B sq) to K sq (!), with an excellent game. (See diagram.)
4. 38…Bxc2 After the exchange of the Queens there is not the slightest doubt that the result of the struggle will be a draw.
