NOTES. 



(«) 3. Kt to QB3 is preferable. 



(b) We prefer 6. B to Q3. 



(c) Black ought to have brought his pieces more into play by 

 12. QKt to B3, to be followed by P to K4 or QJ accordingly, but 

 his position was not good, on account of his weak P on Q3, and the 

 White E on Ra — always a bad combination in this opening. 



(d) This, and the following moves are well calculated, and White 

 obtains a commanding position. 



(e) White plays with marvellous precision, in spite of his con- 

 dueling eight games blindfolded. Black has no other move, for 

 if IS. R to K sq. 19. B to B7. If 18. Kt to Kt3. 19. R to K8 (ch), 

 Kt to B sq. 20. Q to Q5 (threatening m:.te on Kt8), B to K3. 

 21. R (K sq) takes B, R takes R. 22. R takes R and wins. 



(/) An unfortunate move, which enables Zukertort to finish is 

 good style.
