KNOWLEDGE 



[June 1, 1893. 



Notes. 



(a) P to B4 is more forcible now than at any other 

 time. 



(b) In accordance with the modern fashion, which is to 

 play these close games on the King's side. Zukertort's 

 method consisted in castling at once and devoting his 

 attention entirely to the advance of the Pawns on the 

 Queen's wing. 



(c) Though contrary to theory, inasmuch as the King's 

 Pawn is left weak, this move has stood the test of recent 

 practical play. Black's reply is certainly premature, 

 though he cannot play 7. . . B x Kt, 8. BP x B, KtKS ; 

 9. B X Kt, P X B ; 10. Q to Kt4, winning a Pawn. 



(d) A fine move, preventing Kt to K.5, and therefore 

 giving additional force to the threatened advance of the 

 KKtP. Perhaps Black's best reply under the circum- 

 stances was B to R3. 



(e) Hardly necessary, as Black cannot play P to B5 ; 

 but possibly he was providing against B to R3. 



(/) Quite useless. Better would have been 9. . . Kt to 

 Ksq, followed by P to B4 or B8 according to circum- 

 stances. 



((/) Now, however, he should move the Rook, in order 

 to make room for either Knight or Bishop at KBsq, 

 according to requirements. 



(h) To prevent P to B,S ; threatening also Kt to Kt-1 in 

 due time. 



(?) He might play 12. . . Q to K2, \vith a view to 

 B X Kt or P to B3. The alternative was 12. . . Kt to B3. 



(j) Chiefly, no doubt, to prevent Black from freeing his 

 game by Kt x P. In any case 15. R to Kt4 was useless, as 

 (apart from the reply 15. . . . KtxP) Black could 

 defend himself by 15. ... KR to Ksq ; 16. R to R4, 

 Kt to Esq, &c. 



(k) This might wait till White plays R to Kt4, as in the 

 previous note. 



(/) If he intends ultimately to play P to B5, he might as 

 well do so at once, and follow it by P to Kt4, saving a 

 move. 



(m) In order to advance the KRP, and thereby allow the 

 Knight to play to KKt4 viii KR2. 



(n) There is something to be said too for B to K2 with 

 a view to Kt to R2 and P to R5 (or P to R5 at once if Black 

 reply Kt to KB4). Black's next move is quite unintelligible. 



(o) Now perhaps KtxP would have given him chances 

 of breaking through on the Queen's side, but it would be 

 at the cost of exchanging Queens. His next move is very 

 questionable, as it ultimately gives White the open Rook's 

 file. P X P would be better. 



{p} With a view to his next two moves, which lead to the 

 shutting out of the Rook; but as White in any case threatens 

 Kt to B6ch and P to R5, it does not appear that he has 

 anything better to do. The position is against him, his 

 pieces being hopelessly shut out from the King's side. 



(q) P to R6ch first would be better — iide note (r). 



(>■) An oversight. 20. ... P to R8 should be played 

 at all hazards. 



(s) There is nothing else to be done in view of the 

 threatened P to R6ch and R to KBsq. After the exchange 

 of Queens, which is forced, the remainder plays itself. 

 Mr. Lasker conducted the whole game with his usual 

 ability. 



CHESS INTELLIGENCE. 



Mr. Lasker recently defeated Mr. Showalter, the Kentucky 

 Champion, in a match by six games to two, with two draws. 

 By mutual agreement the three games of the previous 

 abandoned match, in which each player won one game, the 

 third being drawn, were included in the score of the later 

 match. It is rumoured that Mr. Lasker intends to 

 challenge Mr. Steinitz to a match for 5000 dollars, and the 

 championship of the world. Mr. Steinitz remarks that a 

 challenge for such a sum would be " entitled to respect," 

 provided that the other conditions are equally fair. 



Herr Walbrodt has won a match from Mr. Delmar by 

 five games to three, with three draws. The deciding game 

 should have been won by Mr. Delmar, who threw it away 

 in the end game. The result of the match, with which 

 Mr. Delmar is not satisfied, seems to show that Herr 

 Walbrodt was either out of form or is not so difficult to 

 beat as has generally been supposed. 



The death is announced of Jean Dufresne, the opponent 

 of Anderssen, and at one time editor of the SchachzeUwin. 

 He was the author of the Lehrtmch den Scluichspiels. 



C. Salvioli is now the editor of the Nuovu Birista dej/U 

 Scacclii, the Italian chess monthly. He is well known as 

 the leading Italian player and analyst. The May number 

 contains an entertaining article on " Chess Knight- 

 errants," with reference especially to Lasker and Walbrodt, 

 and the consternation of the former on landing at Havana 

 at finding Herr Walbrodt in possession of the soil which 

 he (Herr Lasker) " had proposed to himself to cultivate." 

 The following is a pretty two-move problem by G. B. Valle, 

 from a former number : — White : K at KR8, Q at QR5, R at 

 K4, B at KR5, Pawns at KKt3 and Q2. Bhu-k : K at Q6, 

 Rooks at KR7 and QB8, Pawns at KR5 K4, QB4, and 

 QB7. White mates in two moves. Solutions will be 

 acknowledged. 



On May 18th Surrey defeated a weak Sussex team at 

 Croydon by eleven games to six. The previous match 

 resulted in a tie. 



A match of seven games up is now in progress at 

 Simpson's Divan, between Messrs. Bird and Jasnagrodsky. 

 The present score is Bird 3, Jasnagrodsky 2.
