XoTKS. 



(s) Mr. Stcinit/. riglitly dfciiles to act strictly on the 

 (lefeusive. The ohjeet of this move is chiefly to defend the 

 QKtP in case he gets time for P to QR3. It also allows a 

 check at Q3, iu case of need. He dare not play immediately 

 28. P to QR3 on account of 28. . . . KtB4 ! ; 29. BKt2 

 (after 29. PxB. KtxB, Black wins easily); 29. . . . 

 QEKsq; 80. QQ7, KtK6 ch ; 31. KK2, KtQB ! dis. ch. 

 mating or winning the Queen. 



(t) 29. BKt2, QRKsq, would leave him no defence. 

 Nor could he allow the Bishop to he exchanged at K3. 



(«) Ohviously, if 30. PKB4. R x B, 31. PxR, KtKt6 

 mate. 30. P>Kt3 would also lose speedily. 



(r) Preventing KtK2. After 30. . . . RK5; 31. KtK2, 

 KtQ5 ; 32. KtxKt, QR x B ; 33. KtKG, RxP ch ; 34. 

 KKtsq, KRBG : 35. QR4, Black has to waste time in 

 freeing his Bishop. 



(»•) For QKtS see note (x\. If 31. B x P, PxB; 32. 

 QQ7 eh, EK2 ; 38. Q x Kt, RKKtsq wins, as pointed out in 

 the Daily Neirs. 



(.,■) 32. QKt8 loses hy PKKt4 ; 33. BBsq ! (otherwise 

 KtB4 followed by PKt5 wins at once), 33. . . . KtB7 ch 

 winning the exchange. 



(//) Not QxRP on account of ... . RKtu, 34. rB8, 

 BQG ch, and 35. . . . RKt4. 



(j) Shutting out the Queen for the remainder of the 

 game. Mr. Tschigorin judiciously reserves the capture of 

 the KBP. After the exchange of pieces Black has only one 

 check, for the Queen could sacrifice herself for two Rooks. 



(1) 35. PQR3 is useless on account of KtB3 (not Kt x 

 KtP ; 3G. P x B, R QRsq. ; 37. Q x R, etc.) 



(2) A beautiful and unexpected move, which forces a win 

 in a few moves. 



(8) QKtG is the only move to save the Queen. Black 

 would then mate in six moves. 



Mr. Tschigorin's play throughout could hardly be im- 

 proved on. 



The Evans Gambit was also resigned by Mr. Steinitz at 

 the same time. 



Only one move on each side was made since the publica- 

 tion of the diagram in the May number, viz., 3G. . . . 

 K to Ktsq. ; 37. P to QG. 



IHiKjrain aj the final position. 

 Black (9 pieces). 



■\Vbite (10 pieces). 



Black ivxii/ns, 

 [For if 37. . . . Q to B5 ; 38. R x P cb, B x R (K x R 

 leads to the loss of the Queen in four more moves) ; 39. 



Q X R ch, K to R2 ; 40. Q to R5 ch, BR3 (otherwise the 

 Pawn goes to Queen) ; 41. Q to B5 ch ; and 42. Q to K3, 

 winning easily. [ 



Mr. Steinitz has put his two most recent eccentricities to 

 a crucial test, with an unsatisfactory result. The two 

 defences are not only purposeless, but, as pointed out in 

 the Chess Mimthltj, inconsistent with each other. In the 

 one case Mr. Steinitz moves a piece to a bad square in order 

 to be attacked; in the other case he does the same thing in 

 order not to have the piece attacked. In each case the 

 defence is made more difficult than is necessarv. 



Theory of the Chess Openinys. By G. II. D. Gossip. 

 (Messrs. W. H. Allen & Co.) This, the author's third 

 treatise on the subject, is the latest contribution to English 

 chess literature. The book is of prepossessing exterior, the 

 brilliant colour of the binding being rendered still more 

 brilliant by a diagram of what is variously described in 

 the introduction as " Mr. Gossip's historically magnificent 

 performance," or, more briefly (but in larger t}^e), 

 Gossip's Brilliant Matk. TTliis is a position taken from 

 a game in the American Tournament of 1889, which, in 

 Mr. Gos.sip's opinion, should have taken the brilliancy 

 prize.] The author has adopted, for the first time, tho 

 column arrangement of variations. The experiment is 

 not altogether a success : the columns appear to have 

 been arranged regardless of natural sequence, and in at 

 least one case have been repeated word for word. The 

 analytical portion of the work is satisfactory on the whole. 

 Perhaps Mr. Steinitz has been too unquestioningly fol- 

 lowed. The author might certainly " venture to ditfer " 

 more often than he does. The work is mainly, as it pro- 

 fesses to be, a compilation from all the modern sources, 

 but much of it is the author's own. Especially noticeable 

 is the adequate treatment of the Vienna opening, several 

 branches of which have been hitherto strangely neglected. 

 The book teems with personal controversy, more entertain- 

 ing than instructive, vindication of capability being the 

 main topic ; but, judged simply from a chess point of 

 view, it is of undeniable value, being exhaustive and 

 thoroughly up to date. The price is extremely moderate, 

 and the printing and binding excellent.
