4. Kt to Q6 and wins 



(a) If 1. K X B, Black draws by K to B2. 



(ii) Black draws, as White cannot possibly prevent the Black K 

 from occupying either B sq. or B2, for the obvious reason that with 

 every move the Kt occupies a square of different colour ; so does 

 the Black K, which prevents the Kt from commanding either BS 

 or B7 without giving a clieck and having to move again. But put 

 the Kt now (anywhere) on a black square, then White will win.

(;/) A vigorous counter attack. 



(fi) Compelling White to play 

 B X Et, parting with his useful

 winning a piece. 



(i) A subtle device called a

ANSWERS TO CORRESPONDENTS. 



^*# Please address Chess Editor. 



C. E. L. D. — Though a piece giving cheek is pinned in front of 

 its own King — in fact, under no conditions whatever — may a King 

 move into check. 



P.1RTEN0PE asks "whether it is allowable to exch.aiige a Pawn 

 reaching the 8th sq. for a piece of the opposite colour." We do 

 not care whether it is allowable or not — it is nonsense in any case ; 

 and it the law permits of this, then the sooner practice does away 

 with the law the better. Therefore we say decidedly not. 



K.WE.NsnoE points out that our note "j" to game p. 1G2 is not quite 

 correctly worded. White would first move his K to R 2, then the 

 threat of R x Kt would hold good, for if R x Kt at once Kt to B6 is 

 impossible, the white Kt being pinned by the B.
