[August 1, 1892. 



Notes. 



(a] 5. Kt to B3, compelling P to Q3, is also good. 

 White wished, however, to bring about a familiar variation 

 in order to test the position arising from his 11th move. 



(i) Probably as good as anything at this stage, provided 

 that it is followed up as in the text. 10. QKt to B3 

 followed, if Black replies 10. . . . Kt to B4, by 11. E to 

 Ksq is the usual hne of play, from which White certainly 

 derives no advantage. Black's reply is forced. 



((■) The correct reply, as Mr. Steinitz points out. If 

 instead 11. . . . Kt to B4 ; 12. Kt to B5, Kt to K3 ; 



13. Q to Kt4, P to KB3?; 14. B to E6 ! followed by 15. 

 B X P ! wins (Bauer r. Porges). 



(d) Safer than 13. . . . P to B3 ; 14. Q to B4ch, K to 

 Esq; 15. B to B4 : or 14. . . . Q to B2, 15. P to K6 ! 

 with a fine game. White takes in passing in order to get 

 rid of the majority of Black Pawns on the Queen's wing. 



14. Kt to E4 was the alternative. 



((') White's last move was a necessary preliminary to 

 the contemplated E to Qsq. Black cannot well preserve 

 the Bishop, for if he retires to B2 then 18. Kt to B6 ! ; or 

 if to Qsq, then 18. E to Qsq, with the better game. 



(/) To prevent E to K7 after the Knight is driven away. 

 The game is now even, but Black plays to win by advancing 

 the Pawns. As the Pawns have already lost the option 

 of moving either one or two squares, he can hardly do 

 better. White waits their approach with the idea of 

 breaking them up when within reach, reserving for his 

 own Pawns the option of moving two squares. 



((/) 24. ... E to Esq has also something to be said 

 for it. 



(/t) This can hardly be good, but all his pieces are 

 engaged in defence. 



((') Tempting though this is, it was not to be ventured 

 without due consideration. The variations in the next 

 note had to be worked out. 



(J) If, firstlv, 31. . . . B to E5, 32. E to QBsq ! (not 

 32. E to Ktsq.'Kt to Q3, threatening B to B7) 32. . . . 

 Px B (or B to Kt4) 33. E to B7ch, recovering the piece. 



Secondly, and perhaps best of all, 31 BxP!, 32. 



P xB (the Eook dare not leave the Queen's tile) 32. . . . 

 P X B with an even game nearly. 



(A) Better than taking the Bishop at once, as it secures 

 the gain of the EP. 



(/) A strong move, threatening E to Kt5, when Black 

 must exchange Books or lose the Knight. 



(/n) Interesting possibilities result from 40. ... K to 

 Q4, 41. E to KtSch, K to B5 ; 42. Kt to Kt2ch, K to 

 B6, etc. 



(«) Against a player less a master of end-game play than 

 Mr. Mason, White might have tried for a win by 41. E to 

 KtOch, K to K2 ; 42. E to Kt4, etc. The attempt would 

 have been both difficult and dangerous. 



CHESS INTELLIGENCE. 



The Dresden International Tournament began on 

 Monday, .July I8th. The entries were eighteen in number, 

 and included Messrs. Blackburne, Loman, and Mason, of 

 London, Dr. Tarrasoh, of Nuremberg, M. Winawer, of 

 Warsaw (who is probably rather short of practice), and 

 Herr Walbrodt, of lierlin. Of the last-named player a 

 great deal is expected on the strength of his success in a 

 match with Von Bardeleben, who is also a competitor. The 

 score will be given nest month. Gunsberg, Bird, Lasker, 

 and Tschigorin, to mention only European players, are 

 notable absentees, whose place is hardly tilled by the host 

 of Austrian and German stars of lesser magnitudes. 



An interesting match between Dr. Smith and Mr. T. 

 Block has been in progress lately at the City of London 

 Chess Club. The match is live up, and the score at one 

 time was four to one in Dr. Smith's favour. Mr. Block, 

 however, has since drawn up level, the score at the time of 

 writing being four games to each player. 



The City of London Club sent a strong team to Brighton 

 early last month to encounter the Sussex Chess Association, 

 who were defeated by 11-|^ games to 7^, one game being 

 left unfinished, and, in the absence of the umpire, un- 

 decided. 



Brighton is also the scene this year of the annual 

 meetmg of the Counties' Chess Association, begmning as 

 usual on the first Monday in August, and concluding on 

 the following Saturday. The programme has been 

 published elsewhere, and it need only be said that the 

 various tournaments for players of various strength are 

 much the same as usual. Play takes place almost all day 

 at the Brighton Pavilion. 



Mr. Lasker has made arrangements for an American 

 tour in the autumn. Besides giving exhibitions of simul- 

 taneous play, etc., he is willing to contest short matches 

 with the leading Transatlantic players.
