8. Q to Q3 



Another good continuation for White at move 4, if he is not inclined 

 to run tlio risk of taking the King's Pawn, is P to E3, which leaves 

 Black no other course than to exclnnge Knights, after which White, 

 retaking with the Queen, will bo slightly ahead in the development. 

 Lot us assume, however, that he has captured the King's Pawn, and . 

 that, after taking the Queen's Pawn with his Bishop (dearly the best 

 move), he plays 6. P to QB3. Black may now take either tho Knight 

 or the Knight's Pawn with his Queen. 



In the lirst place : — 



6. P to QB3 

 In this case, it is very doubtful 



check. For example : — 



7. Q to R4 (ch) 



8. P X Kt 

 Better than 8 . . . Q to B2. which would be met by 0. Q to B2. 



0. Kt to B3 

 If !». B to Kt3, then 9 ... P to QKt4. 10. Q to Ri 

 White has an uncomfortable game. 



9. P to QKt4 



10. Q to R5 (apparently best) 10. P x B 



11. Kt x KtP 11. Qto B3 



12. P X P 12. QtoKt2 



And. although White has the advantage, it will not be easy for him 

 to win with his ragged Pawns. 

 On the other hand, by playing — 



7. P X Kt 7. Q X P 



8. Q to Kt3 



he at once obtains a decisive superiority If now 8 



then 9. B X B, Q X P (ch), 10. K to Qsq., &c. 

 In the second place : — 



G. P to QB3 (!. Q X KtP 



7. Q to R4 (ch) 7. P to B8 (best).

 In this position White's best course seems to be 



8. B X P (ch) 8. K to K2 



9. Q to Kt4 (ch) 9. K to E3 



10. Q X Kt 10. Q X R (ch) 



11. KtoK2 



Black has now the choice of several moves, of which 11. . . . B 

 to Kt5 (ch) and 11 ... Kt to R8 look the most promising ; but in 

 any case White appears to have a winning advantage. 



Returning to the position on the diagram, and supposing White to 

 plav 



8. P X Kt, 



wo believe Black may reply by 8 ... B to Q2. with a fair pro- 

 spect of making good his defence ; but if he captures the Queen's 

 Bishop, he will lose in a few moves ; e.g. 



8. Q X B 



9. Kt to Q B3 9. Q X R 



10. B X P (ch) 10. K to Qsq 



11. Q toR5(oh) 11. P to Kt3 



12. Kt X P (ch) 12. K to B2 



13. Q to K 5 (ch), &c. 



Mr. Kuka has developed the same idea 

 Vienna game, tho opening moves being 



White. Black. 



1. PtoK4 1. P to K4 



2. Kt to QB 3 2. Kt to KB3 



3. B to B4 3. B to B4 



vai'iation of the 



Of course, the same position is arrived at in a variation of the 

 Berlin Defence to the King's Bishop Opening. Mr. Kuka now pro- 

 poses 



4. Kt to Q5 



We think that this move may be met by P to QB3 even more 

 advantageously than before, as the adverse bishop is not so well 

 posted at QB4 as on his own square. But, to continue the variation 

 as suggested by Mr. Kuka, let Black play 



5. P to Q4 

 G. Q to Kt4 



7. Q X KtP 



8. Q X B (ch) 



9. Q X Q (ch) 



10. B X P 



11. Kt to B3 



12. Kt X B 



13. B X BP 



14. B to Kt8 



15. B to Kt5 (ch) 



4. Kt X P 



5. B X P 

 G. P to QB3 



7. P X Kt 



8. K to K2 



9. K X Q 



10. Kt X P 



11. Kt X R 



12. P X Kt 



13. K to K2 (?) 



14. P to KR4 



Kuka remarks that White wins, "because the Black 

 lannot escape, and the other black pieces are still at 



and Mr. 



Knight . 



home." But, if instead of Black's 13th move, which we have 

 marked with a query, he play 13 ... P to Q3, it is difficult to 

 see how White is to obtain any advantage. 14. B to Kto (ch) .and 

 15. B to R4 seem to be necessary moves in order to secure the 

 Knight, and Black, after playing his King to B2, may continue 

 with B to B4 and Kt to B3, having by no means a bad game. This 

 result, however, does not detract from the credit due to Mr. Kuka 

 for his original and interesting suggestions. 



The following is an amusing end-game puzzle : — 

 Black. 



White. 

 White to play. In how many moves can he force a mate ?
