[Apbel 1, 1891. 



'/ricks— AB, 2 ; TZ, 1. 



rnci-s— AB, 3 ; YZ, 1. 



Note. — Trick 3. — YZ being at the score of 4, Z de- 

 termines not to open trumps, and leads his fourth-best 

 chib. 



Tkick 5. Trick 6. 



Tricks— XB, S ; YZ, L'. 



Tricks— AB, 3 ; YZ, 3 



Note. — Trick 5. — Z's discard shows five chibs originally, 

 and enables his partner to count his hand. 



Trick 6. — The four of trumps is now marked in Y's 

 hand, and the three best trumps clearly lie between A 

 and B. 



Tricks— AB 



Note. — Trick 7. — Z therefore continues the trumps ; 

 for. if the adverse trumps are all in one hand, AB must' 

 win the game in any case, since they will make three tricks 

 in trumps, and one, at least, in clubs. Accordingly, Z 

 plays on the assumption that the adverse trumps are 

 divided. As the cards happen to lie, he would win the 

 game equally by continuing the club suit ; but this would 

 be dangerous, as AB might be enabled to make their 

 trumps separately. 



Tkick 10. 

 Y 



Trickf—AB, f. ; YZ, 4. 



Tricks 11 to 13. — A leads ace of diamonds, on which Z 

 plays his last trump, and YZ then make two tricks in 

 clubs. 



YZ Score the Odd Trick and win the Game. 



A's Hand 



H.— Kn, 10, 9. 



S.— Qn, 5, 3. 



D.— Ace, Kg, Qn, 10, 2. 



C. — Ace, Qn. 



Y's Hand. 

 H.— 7, 4. 



S.— Kg, Kn, 8. 

 D.— 9, 7, 6, 5. 

 C— Kn, 9, 7, 3. 



B's Hand. 

 H.— Kg, Qn. 

 S.— Ace, 10, 9, 7, 4, 2. 

 D.— Kn, 8, 3. 

 C.-Kg, 4. 



Z's Hand. 



H.— Ace, 8, 6, 5, 8, 2. 



S.— 6. 



D.— 4. 



C— 10, 8, 6, 5, 2. 



Remarks. — Trick 2. — If Z intended to lead trumps, he 

 woidd trump with the five and lead the three ; but for the 

 moment he is not anxious to expose his strength. 



Trick 3. — If Z leads a trump, AB make at least the odd 

 trick. B wins with the queen, and returns the knave of 

 diamonds. If Z rulis and continues with the ace of 

 trumps and then a club, A wins with the queen of clubs, 

 and leads the knave of trumps and then the ten of dia- 

 monds ; if Z ruii's and opens clubs at once, A wins with 

 the qlieen, and leads the ten of diamonds and afterwards 

 (however Z plays) the ace of diamonds ; and, if Z dis- 

 , cards his spade on trick 4, B leads the ace of spades, and 

 Z cannot save the game. To retiun to the actual game, 

 we may observe that those players who adopt the " plain- 

 suit echo " would, in Y's place, play the seven of clubs 

 instead of the three. 



Trick 4. — Mr. Hughes remarks that " A leads a spade, 

 and not a diamond, as he does not know whether Z is 

 strong or weak in trumps." We think, nevertheless, that, 

 as A has command of the clubs and some protection in 

 spades, and as YZ are four up and Z is rirffing diamonds, 

 the correct lead is the knave of hearts. This, however, 

 would not save the game imless YZ played badly. 



Trick 6. — Y counts three clubs and five trumps re- 

 maining in his partner's hand, and therefore leads a 

 trump. 



Trick 9.— The beginner should note that even at this 

 point Z would lose the game by continuing the trumps 

 instead of clearing his clubs.
