rally retire when a position is obtained which can bo reached one 

 move earlier by playinj; the Krenrh defence. 



(d) White's centre Powns are weak, and the Queen is well 

 posted there to prevent their advance. 



!e) A very clever device, it leaves White no alternative. 

 /) With the intention of advancing P to KG if possible. 

 (y) We wonld have played Q to Q2, White could not then ad- 

 vance the Pawn which is threatened by the Kuok. 



(h) A bold course, which hardly promises more than a draw. 

 Blackburno truly pointed out that R to B4 would force the ex- 

 change of the Queen and two Rooks, and leave Black with a 

 slightly preferable Pawn position.

WlXAWER. 



(i) The endinpt is very difficult for White, on account of the 

 ■weak position of hia Pawns. Played to prevent KR to K2 by 

 ■Q to Kt3 ch. 



(J) This creates a weakness of which White cleverly avails 

 himself in his subsequent play. P to QR4 looks stronger. White 

 might reply to this with Q to B3. 



(i) If K to B2, then Q to KR8, after the exchange of Pawns. 



(I) Threatening Q to R8 (ch) if R takes P. 



(m) Wliite never again retired his Queen from that quarter, 

 although Blackbume tried hard to lure him away ; and, as neither 

 Rooks could move without leaving either the Rook's or Knight's 

 3'awn unprotected, the game was given up as a draw after about 

 <35 moves.

(c) Giving White a substantial advantage. 



(d) A fine stroke, which practically decides the game. Black 

 could not retake on account of Kt takes P (ch), winning the 

 Queen. Black struggled on for eight more moves, and then 

 resigned, after 3^ hours' play. 



ANSWERS TO COEEESPONDENTS. 

 •«• Please address Chess Editor. 



F. W. E. — In game between Steinitz and Winawer, p. 272, 

 Black's 9th move is B to Q3, instead of K3. 



T. T.— See solution of No. 84, p. 256. 



L. G. Rylaxds.- — The fact of a piece being pinned does not 

 deprive it of its checking powers. 



S. L. B. — It is as you say, the combination that was sprung upon 

 "Z" was one move deep. It is a true specimen of play that 

 occasionally occurs at tournaments. A more vexatious thing than 

 that even happened to us. We opened a game as follows: — 

 1. P to K4, P to K4. 2. Kt to QB3, Kt to QB3. 3. B to B4, Kt 

 to B3. 4. Kt to B3, Kt takes P. 5. B takes P (ch), K takes B. 

 G. Kt takes Kt, P to Q4. 7. KKt to Kt5 (ch), K to Kt3 (r). 8. 

 Q to B3, P takes Kt (r). 9. Q to B7 (ch), K takes Kt, having, 

 partly by our own enterprise, and partly by our opponent's weak 

 play, arrived at this position, which yields some very interesting 

 analysis, in most of which the tenacious Black King comes out 

 victorious. We played P to Q3 (ch), and soon obtained the worse 

 game. But if the same check is given bv P to Q4, the game can 

 be forced, i.e.— 10. P to Q4 (ch), K to E5. 11. P to KR3, P to 

 KKtS (best). 12. P to Kt3 (ch), K to R4. 13. P to Kt4 (ch), 

 K to E5. 14. Q to QKt3, and wins. 



A Learner. — 1. P to QB4 constitutes the English opening; it is 

 usually followed by P to K3. 2. P to K3, Kt to KB3. 3. P to Q4, 

 P to Q4, &c. 



R. Hallidat. E. T. Eidsdale. — In the game of Mackenzie v. 

 Bird, p. 302, the diagram is misprinted, but the text is correct.
