CONDITIONAL PROBLEM. 

 By W. De Moegan. 



Black (5). 



White (6). 



White mates in three moves, on condition that no piece 

 may make two consecutive moves. [In order to prevent 

 such solutions as 1. P to Kt4ch, K x P ; 2. Q to Kt8 

 mate (!), it seems necessary to make an exception in favour 

 of the Black King.] Solutions will be acknowledged. 



Readers of Kxo^\i.edge will be interested to know that

 Prof. De Morgan. 



CHESS INTELLIGENCE. 



The first portion of the Steinitz-Lasker match is now 

 over. Eight games were played at New York, resulting 

 in four wins for Lasker, two for Steinitz, and two games 

 drawn. The play, so far, has been of a brilliant character 

 on both sides. Mr. Lasker has played the Ruy Lopez 

 consistently, an opening in which Mr. Steinitz has 

 succeeded in discovering just the cramped awkward defence 

 that he revels in. Mr. Steinitz has of late years always 

 done badly in the earlier stages of his matches. Under 

 stress of urgent necessity he may possibly abandon the 



defence referred to ; in any case, he is sure to play his best 

 as the match enters on its final stage. The next instal- 

 ment of the match is just commencing at Philadelphia. 



The North c South match was played in London on 

 April 7th, with one hundred and seven players on each 

 side. The result, after five hours' play, was a rather 

 decisive victory for the South by sixty-four and a half 

 games to forty-three and a half. No doubt the Northern 

 team were severely handicapped by the long distances 

 which many of them had to travel, and also by the absence 

 of Mr. Skipworth and many of the leading Lancashire 

 players. On the Southern side notable absentees were 

 Messrs. Chepmell, Guest, Hunter, Mortimer, and Wayte, 

 not to mention Mr. Donisthorpe, who deserted to the 

 Northerners. 



After the match the two teams were entertained at 

 supper by the Reception Committee. The arrangements 

 throughout were excellent. Mr. Blackburne again acted as 

 umpire. 



An analysis of the Southern score shows that the County 

 players came out with a better average than the Metro- 

 politan ; Surrey, Sussex, and Somerset contributing in a 

 large measure to the victoi-y of the side. At the same 

 time, it should be mentioned that most of the Surrey 

 players are practically Londoners and members of London 

 clubs. Last year no game was lost on the first twenty 

 Southern boards ; this year only one game on the same 

 boards was lost. The Northern successes were almost 

 entirely on the middle boards (Nos. 33 to 871. Here they 

 obtained a slight majority, but not sufficient to balance 

 the failure of the two ends of the team. 



Late News.— Mr. Lasker won the ninth game.
