Opening Lead: Versus Trumps (1)

(This, and articles like it can be found at andrewrobson.co.uk.)

Good Leads: The choice of opening lead decides the fate of many contracts – about half of all contracts that start life in the balance. Sometimes the defence have to win their tricks quickly – when dummy has a long strong suit. Sometimes the defence can sit back and play a waiting game. It’s hard to know which without a sight of dummy, so if you are lucky enough to have an ace-king combination, you should always lead the ace (top of a sequence) and have a look at the dummy. Then you can decide what to do with more information. Ace-from ace-king is most decidedly Andrew’s favourite lead: a 10/10 lead.

Other good leads (9/10) include leading the king from king-queen. This is good because you are happy if the king forces out the opposing ace, as this promotes your queen; you are even happier if your king wins the trick, for now it looks like partner holds the ace. The other 9/10 lead is a singleton: you void yourself in the hope of being able to trump a further round of the suit.

Exercise: After the unrevealing auction by the opponents of 1-4, what would you lead from:
♠ 9 6 3
9
A K 8 3
J 8 4 3 2

You have a singleton heart, yet that is not the best lead. Better is to lead A to have a free look at dummy. You can always switch to  9 should a look at dummy make that attractive. Or cash  K. Or even switch to a club. You won’t know until you see dummy and that’s why  A is best: it keeps all your options open.

 
Tips for Intermediates

Rebidding Notrumps

(This, and articles like it can be found at andrewrobson.co.uk)

The normal order of priority between the five game contracts is:
1st: 4 , 4  with an eight-card fit
2nd: 3 NT
3rd: 5 , 5  (some way behind).

I tell my students (tongue-incheek) to play Five-of-a-Minor just once a month. It will only be best if all of the following are true:
a) No eight-card major fit.
b) A short suit unstopped in both hands (3 NT out).
c) Good shape/loads of points.
Say the bidding has begun 1 -2 -3 NT (17-19). Are you passing, or bidding that once-a-month 5 ?

(i) Pass. The spade void is not notrumpy, but it is partner’s suit. Turning to hearts, give partner as little as  xxx and you would rather play 3 NT (four heart losers on a 4-3 split) than 5  (three losers and down you go). See deal.

(ii) Pass. Without a singleton, to even think of 5  would be misguided. The diamonds should run nicely in notrumps.

(iii) 5 . Because of the side-suit void, and the “slow” minor-suit holdings. Top cards will need to be dislodged and you may not have time in 3 NT after, say, partner’s one heart stop has been dislodged.

  2. Mistake. Two more tricks to make than 3 NT. A void in partner’s suit is not of huge concern and pass is indicated.

5 was quickly down. West led  K, continued with  Q, then led  4 to East’s  A. East led his thirteenth heart, and when West ruffed with  9, forcing dummy to overtrump with  Q, East’s  J104 was promoted into a trump trick. Down two.

The defence can take the first four heart tricks against North’s 3 NT, but that’s it (diamonds run - starting with  Q). Game made.

If you remember just one thing...
Try to avoid Five-of-Minor.

On this deal from the World Championships in Bali, I want you to shout out when, declaring 4 as South, you can deduce where the missing king of clubs lies. Study the auction first – right from the very beginning.

  1. It would be nice to have a Weak Two in diamonds available.
  2. Two-and-a-half Hearts. Not because you’re really worth it – those jacks could all be worthless [indeed in a sense they all are – as you’ll see from the play]; but because it takes away bidding space from East
  3. You have not really been invited to the party – partner’s 3 was not inviting game, rather just competing. However your heart holding looks so much better-suited to play than defence and 4 down one is better than conceding 4.

West leads the five of diamonds and...

Can I hear you shout? You should know already where that king of clubs lies. Here is how. West would lead a top spade holding ace and king, therefore East has either the king or ace of spades. 

West would lead a high diamond if he holds a sequence and would not lead away from the ace; therefore West is leading from the king or queen and East holds acequeen or ace-king. Together with East’s top spade, there is no room for East to hold the king of clubs, or he would have opened the bidding. Ergo, West holds the king of clubs. 

East wins trick one with the ace of diamonds and leads a second diamond (the spades can wait). Declarer ruffs, draws trumps in three rounds (East with one), then cashes the ace of clubs, spurning the finesse. [If he wishes, he canlead the jack of clubs from dummy and flamboyantly rise with his ace – he can always finesse against East’s nine later, reaching dummy by ruffing the third spade].

West’s king of clubs delightfully falls under your ace and you can cash your three promoted clubs and merely give up two spades. 10 tricks and game made.

You did not know that West’sking of clubs was singleton – only that he held the card, rendering the finesse pointless. Or perhaps you did start to suspect it was singleton... 

West must have six spades – if he holds five, East has three and would have supported in the auction. East would not volunteer 3 without six cards, so West has three. When you draw trumps, you discover West holds three. That leaves room for just one club...the king.

Elementary, my dear Watson.
