luunoly, if in tho first varintion, instead of 10 Caatlos, White 



play tho tompting move 10. Kt. to H.7. Black gets the advantngo

exceedingly strong attack. Ho chiefly threatens Kt. t o B.6, which 

 White cannot retake with tho Pawn, on account of B. to R.6.ch. 

 Tho Queen has no place to go to if attacked by tho Kt., as 

 Q. to K.sTch. is thereby threatened. White would lose his 

 Qneen if, in reply to Kt. to'BA he should play Q. to Q.aq.,— by

Again, it in the first variation White docs not play 8.

has two good plans to pursue, firstly B. to Q.3., R. to K.sq., and 

 KTto Kt^. ; or, secondly, ho might play B. to Q.3 , 

 B. to K.3., Q. to Q.2., and Q.R. to K.Kt.sq^ so as to proceed with 

 an attack on the King's side by P. to K.Kt.4. 



Of course, statements of these kind are only general, and meant 

 to show the nature of the position, but real play ha.s, of course, 

 to be modified, even according to weak reiilics of an opponent. 

 But whatever White should do. Black should obtain the better 

 game, owing to his good position. •

invariably got tho better game, which move, therefore, is tho 

 proper defence against this strong counter-attack.* 



• To Mr. Gossip is duo the credit of advocating this stroig 

 move and the ensuing variations. 



SAi.Foan. — Yon have not tranHgressed the rules of chess, but your 

 solution of Problem C is unsound. After Q. to Q.3.rh., B. takes 

 Q., P. takes B., why should not Black Uke B. with P. in his turn ? 

 Uow would White mate then on the move ? 



Jamks M.m .vii'lNi!.- If (1) Kt. to Kt.o. in Problem C, 1. P. to Kt.4., 

 2. P. takes K.P., Black can play Q. to Q.'a 5th ch., and there is no 

 mate. 



CBmoTYPE. — If Q. takes K.B.P., in Problem 6, Black mores 

 Q. to Q.U. square; then, if Q. takes Q., P. to Q.B.3., aad there is no 

 mate on the move. 



li. FiTZ lI.KiiT.— Your letter fonvarded to Hades, " Mcphisto," 

 being tho author of the analysis in question. Yon should hare 

 addressed Chess Editor. 



The Cheu Player's Chronicle calls our attention to the following 



beautiful problem by Mr. Grimshaw, in which the idea underlving 



tho second solution of his problem, Xo. G, p. 100, is embodied. 



Problem, No. 12. 



By "W. Orimsliaw. 



Blick. 



White. 

 White to play and mate in four move?. 



Unfortunately there are two solution?, one beginning Q. takes P., 

 the other (the author's) beginning Q. takes R. (at R.'s 2.). The 

 Chronicle believes that the solution given in the Il'iistrated London 

 }^eu-s was not the author's ; how, then, was it that no reference 

 was made in the Illustrated to any other solution ? The Chronicle 

 appends a note of interrogation to our remark that if, in 

 Problem 6, Queen goes at once to K.'s 6th, mate is only tlireatened 

 in one way. How is mate threatened, e.tcept by B. takes P. ? 

 After 1. Kt. to K.B.5., 1. B. takes Kt. 2. Q. to K.'s Gth, mate is 

 tlireatened also by Q. takes B., — that ia, as we said, in two ways.
