BLA'K. 



(f) In order to prevent the exchange of Queens by Black playing 

 Q to B5. 



(/) Wliite, we tbink, would not 

 have given up this piece i£ he had 

 not been minus a Pawn. The 

 attack, though considerable, does 

 not promise a win. It does, how- 

 ever, seem as if a draw by per- 

 petual check always remained 

 available. That this was not the 

 case is due to Black's correct play 

 and capital defence. White would 

 gain nothing by playing 17Q to 

 R3, P to KKtS, &c. 



(//} In order to gain time. Black 

 four times played his K to B sq 

 and B2 before playing K to K2. 



(A) If P X B White draws by per- 

 petual check. 



White, 



The following was played in the late Tournament at the British 

 Chess Club. It contains a noteworthy variation of the French 

 defence : — 



XOTRS. 



(a) Many players do not like this move, and give preference to 

 Kt to KB3, and keep the B on K2. 



(J) i. P X P is usually played here. In reply to 4. B to Q3, Black's 

 best is P X P. 5. B x P, Kt to KB3, whereby be gains time for 

 development. 



(f) 5. P X QP is also admissible. 



Id ) This is bad, and leads to a lost game. If, instead B to R4, 

 then 7. P to QKt4. P x Kt. 8. P x B, Q x P. 9. B to K3, Kt to 

 Q2. 10. Kt to K2, with an even game. 



(t^) White obtains a piece and two Pawns, with a strong attack, 

 for the Rook. 



(/) Q X B is preferable. 



Ig) This move gives White an 

 overwhelming attack. Black dare 

 not take the Kt ; he would speedily 

 lose, as White could then play. 

 14. Q to B3 (ch), compelling 

 Kt to B4, then 15. P x Kt w:.uld be 

 fatal. White also threatens now 

 to play Q to R5, against which 

 move Black must be on his guard. 

 Black's game, however, is hope- 

 lessly compromised now. 



(A ) Threatening 16. P to Ko, 

 also 16. B to Kt5, followed by 



17. BxPand 18. Qy.T,kc. 

 {i ) If Kt to K4 instead then . 



foUows. 1 7 Kt to K Kt5, R to R sq. Wnrre. 



18. KtvB, RxKt. 19. Kt X P (oh), K moves. 20. Q x Kt and wins, 

 (j) If P X P instead, White continues with 18. Q x P. 



An interesting variation in the Scotch defence :— 1. P to K4, 

 P to K4. 2. Kt to KB3, Kt to QB3. 3. P to Q4, P x P. 4. Kt. 

 X P, Kt to B3. This is the German defence to the Scotch gambit, 

 and should lead to an even game. Zukertort played it throughout 

 in his match with Blackburn. 



If now White plays 5. Kt x Kt, Kt P x Kt. 6. B to Q3, P to 

 Q4. 7. P to Ko, Kt. to Kt. 5. 8. Castles, B to QB4 (threatening 

 Q to R5). 9. P to KR3, Kt x KP. 10. R to K sq, Q to B3. 11. 

 Q to K2, Castles. 12. Q x Kt, QxP (ch). 13. K to R sq, 

 B X RP. 14. P X B, Q to B6 (ch). 15. K to R2, B to Q3 winning. 



Anotlier variation in which Black's development proceeds on the 

 Q side is as follows :--5. Kt x Kt, Kt P x Kt. 6. P to Ko, Q to 

 K2. 7. Q to K2, Kt to Ql. 8. P to QB4, B to R3. 9. P to Q Kt3, 

 Castles; &c. From these two variations it may be seen that the 



advance of the KP does not result favourably for White. Steinitz 

 played in his second .game against Zukertort : — 



5. Kt to QB3 5. B to Kt 5. 



6. Kt X Kt. 6. KtP X Kt. 



Now White proceeded with 7. B to Q3, P, Q4. 8. P x P, P x P. 

 9. Castles, Castles, and tlie game became even. Another w.'iy of 

 continuing the attack is by playing 7. Q to (H, which produces 

 some exciting play. 



7. Q to Q4 



8. P to B3 



9. B to KKt5 9. 



10. B to Kt5 (ch) 10. 



11. Q to Q2 



12. Castles 



Q to K2 

 P to Q4 

 P to B4 

 K to B sq (best) 



11. P to Qo 



12. P to KR3 (best) 



Obviously Black could not take the Kt, on account of 13. tj tu 

 Q8 (ch). Black would not improve his game by playing B to Kt2 ; 

 for, although White is thereby prevented from playing Q to Q8 (ch), 

 he will have a good game — i.e., 12. ... B to Kt2. 13. Q to B4, 

 P x Kt. 14. P to Ko, with a strong attack. 

 13. BxKt 

 If the B retires, then P to Kt4 follows, making room for the K, 

 which then enables Black to play ? x Kt. 



13. PxB 

 P to QR3 14. PxKt 



Q to Q8 (ch) 15. Q X Q 



R x Q (ch) 16. K to Kt2 



R X R 17. P X P (ch) 



KxP 18. KxR 



14. 

 15. 

 16. 

 17. 

 18. 

 19. PxB 

 With an advantage for Black.
