Notes by E. Schiffers.

1. 5…a6 A move frequently adopted by Morphy.
2. 6.Bd3 If B to R 4, then P to Kt 4 and P to Q 4, leading to a known variation of the defence, 3..... P to R 3. 6. B k Kt, P x B, gives an even game.
3. 7.c4 This line of attack was played by Zukertort in games with Rosenthal and with Winawer.
4. 7…Nxd4 Rosenthal, in one of the games of his match with Zukertort, played 7. B to K Kt 5. White wins if 7. B to K 3, because then 8. R to K sq.
5. 8.Nxd4 Stronger play would have been 8. PxP, and if Kt to K B 3; then g. Kt X P (threatening Q to R 4, ch), Q x P; 10. Kt to Q B 3, &c.
6. 9.cxd5 9. R to K sq might have been followed by B to K 2; 10. B x Kt no (P X P, Kt to B 3), P X B; i r. R x P, P to Q B 4, and Black is a Pawn ahead.
7. 9…Nf6 It is evident that Q x P, B x Kt, &c., will not do.
8. 11.Bc4 These moves clearly demonstrate the inconsistency of White's attack.
9. 12…c6 P to B 4 was stronger.
10. 20.h4 White has already lost all attack.
11. 21…Bxh5 B to B 4 or P to K R 3 would have been better; the Pawn at R 5 remained weak, and Black would not have lost the important Queen's Pawn for it; eventually White very skilfully played for the draw.
