[July 14, 



Editor determined to make this the subject of further investiga- 

 tions, and the game proceeded 



Ktjakes Kt 

 PtoQl 



KKt to Kto. 



This move is of an attacking nature. Black, of course, cannot tako 

 the Knight. P to KK3 would also bo weak, on account of Kt takes P, 

 and, if K takes Kt. then Q to R5(ch) would give Wliito a fine' 

 attacking position. Chief Editor says in his note : " An ugly move ; 

 not, I think, in the books. The two Knights and the Queen threaten 

 serious trouble on my King's side. Uowever, I tako the Bishop ;" 

 therefore 10. P takos B. 



(To be continual) 



Xote on the Steinitz-Winawer game, p. 86. 

 Deab Mephisto, — I have been so backward with my work the last 

 few weeks, owing to (what is unusual with me) ill health, that 1 

 have had no time to open a chess-board. Looking, now, over the 

 singular game (for a great niatcli) between Uerrcn Steinitz and 

 Winawer, on Friday, June 23, pp. 85, 80, 1 note that the ingenious 

 rariatioa suggested by you on move 16, while effecting a certain 

 draw, if Black moves K to Kt(sq), gives White (at least, 1 think 

 so) a win, if Black moves K to K2. Your continuation is — 



16. Q to KR5 16. Kt to Kt3 



17. y to K6(ch) 17. K to K2 



18. Q to Kt7(ch) 18. K to Qsq 



19. Kt to B7(cli), and perpetual check follows. 

 18. K to Qsq 



While plays 19. Q takes P(ch) 



I do not see how Black can avoid mate in a few moves. Some of 

 the variations are very pretty, but I see nono ia which mate is not 

 forctd. Is it not so ? 



About what follows I feel more doubtful, having only considered 

 the suggested line of play in passing, when running through the 

 game, as actually played. It seemed to me that if at move 14, 

 White (instead of playing Kt to K2, giving the position shown in 

 the diagram at p. 86) should play P takes P, and after P takes 

 P, which seems forced, should play Kt to KB3 (sacrificing Rook), 

 and after Q takes K, Kt to KKt, 'he wins by force. Black's best 

 move seems to bo to return his Q to QR8 ; but Wiite can then 

 play Q to KR5, and if Black Queen checks, move K to K2, safe 

 from further check. What, then, can Black do ?— In haste, faith- 

 fully yours, R. A. PllOtldR. 



if after 



For the better understanding of these excellent remarks, we give 

 the above diagram of the position after Black's thirteenth move. 

 We will first comment upon the second part of Mr. Proctor's letter, 

 in which ho asks whether, in the position given above, White would 

 have done better to play 



It. P takes P 14. P takes P 



(14. Q takes P would Ijc bad on account of B to KtS) 



15. Kt to B3 15. Q takes li 



16. KttoRl 



This certainly looks promising, and Black would probably lose if ho 

 nr/w were to play Q to QI{8. He has a better move at his dis- 

 I>09al, however, which is 



10. Q to KB8. 

 White may continue with 



17. B to KC(ch) 17. K to Kt.sq 



But afti>r this there is nothing to l>e done of a determined charaetc-r. 

 F..r if 18. Kt to Kl Black replied with 18. K to B2, in which case 

 White would do Ijest to draw by Kt to Q6 fch.), for should the Queen 

 check on K5 Black tan with ailvantnge cover with the Knight. 



Or i( 18. Q to KR5, Black can also play 18. Kt to Kt3, for in reply 

 to 19. Kt takos Kt there follows 19. Q takes P (oh). 20. K moves. 

 20. Q takes Kt with an advantage. 



In reply to 16. Q to KB8 White could also proceed with 17. P to 

 Kt3 or B to K3, which would be met (wo think effectually) by 

 Black with 17. P to KRl. Finally, in reply to 17. Q to Q4. 

 17. Kt to KI-. 18. B to K6 (oh). 18. K to K2. 19. P to B4. 

 19. K takes Kt. 20. P takes Kt. 20. K to K2, Ac. 



As regards the first |)art of Mr. Proctor's letter, he is quite right 

 in saying that Black must accept the draw by moving the K to 

 Kt S(|. Wo wore so elated at our analytical success in finding out 

 the draw, tint wo ovoriooked that if Black plays K to K2 White 

 will win. Resuming the [wsition of the diagram, the variation pro- 

 ceeds tliua : — 



14. Kt toK2 It. Q takes R 



15. P takes P 15. P takos P 



16. Q to KR5 16. Kt to Kt 3 



17. Q to K6 (c h) 17. k t()_ia8q 

 IS. KtU)_K8 IS. K to B2 

 19. Kt toQ6(ch ) 



If Black now plays 19. K to K2, instead of KtoKleq, White 

 will win as follows : — 



19. K to K2 



20. K to Qsq 



21. K to B2 



22. K to Qsq < 



23. Kt to K2 



(„) or (b) 



20. Q to Kt7(ch) 



21. Q takes BP(ch) 



22. Q to B3(ch) 



23. B to Kt5(ch) 



24. Q to R.i(mate) 



(a) 22. K to Kt(sq). 23. Kt to Kt5(ch) and mate next move. 



(()) 22. K to Kt3. 23. Q to Kt4(ch). (If K to B2, proceed as 

 before.) 23. K to B3. 24. Kt to Q4(ch). 24. K to Q4. 24. Q 

 to B4(mat6).
