Obey the Law? Board 22 from Wednesday 18th
… it’s usually best to obey The Law, but there are exceptions:
Dealer: ♠ 7 Table A
North ♥ J632 West(B) North East South
Both vul ♦ KJ96 - pass 1♠ dbl (1)
♣ Q1096 4♠ (2) all pass
♠ AQJ83 N ♠ K109652 Table B
♥ 85 W E ♥ Q74 West(B) North East South
♣ 532 ♣ K 3♠ (2) 4♥ pass pass
♠ 4 pass (3)
And what happened? 5♠-2, 4♠*-1, 4♠-1 three times, 4♥-1, 3♠= and 5♥*-3.
The bottom line:
- Decide how high you want to pre-empt - 3♠ or 4♠ at (1) here – and do not bid again.
An ‘automatic’ re-opening double? Board 21 from Monday 23rd
When playing negative doubles, remember the ‘automatic’ re-opening double in case partner has a penalty hand. But there are exceptions when you should not re-open with a double:
Dealer: ♠ 982 West(A) North East South
North ♥ 76 - pass 1♣ 1♥
N-S vul ♦ K9832 pass (1) pass 2♥ (2) pass
♣ J86 3NT pass 6♣ (3) all pass
♠ KJ5 N ♠ AQ63 (1) What did you bid with this West hand A in this
♥ KJ1052 W E ♥ - week’s quiz? 3NT is possible but at this
♣ A3 ♣ KQ107542 pass partner’s ‘automatic’ re-opening double.
♠ 1074 (2) But this East hand is totally unsuitable for a
♥ AQ9843 re-opening double, and this 2♥ cue bid is fine.
♦ QJ10 (3) Partner has shown about opening values with
♣ 9 good ♥’s and this bid is also fine.
And what happened? 6♣= three times, 5♣=, 3NT+3 twice, 4♠+2 and 2♥*-2.
The bottom line:
- There are exceptions when you should not re-open with a double, see the negative doubles page in the conventions section of the website.
Dave’s Column Here is Dave’s first input on the play of the hand.

Dealer: ♠ A8 Book bidding

♠ Q95 (3) 2 keycards + ♥Q
♥ A1096 .
♦ A East leads the ♦J, do you see a way to make the
♣ AK742 contract with normal breaks?
In his classic gem “Why You Lose at Bridge”, S.J. Simon introduced the theory of ‘half a loaf’. His Philosophy suggested bidding to the maximum opposite a competent partner, but settling for half a loaf opposite a less competent one.
An average declarer takes dummy’s ♦A and counts possible winners. He recognizes that he lacks the entries to score enough ♦ ruffs in dummy, so he tries to bring in dummy’s ♣ suit.
He cashes two trumps and dummy’s top ♣’s, hoping to drop the ♣Q. When it doesn’t fall, North’s chances approach zero. He concedes a ♣ to East’s ♣Q and East leads a third trump; North is limited to eleven tricks.
A more competent North counts on 4 ♣ winners. The ♠A and ♦A, four trump winners and two ♦ ruffs in dummy.
At trick two he leads a low ♣ from dummy. East’s ♣Q wins but East has no effective response. If East returns a ♣ (nothing else is better) then dummy wins and two ♦’s are ruffed high, using the trump suit for communication. Then he leads a ♠ to his ♠A to draw the last trump and uses his last ♣ to reach dummy’s good ♣’s.
The winning line depends upon finding a 3-2 ♣ break (68%), while dropping a doubleton ♣Q is only 27%. Opposite a declarer who can recognize the difference, bid the slam. Opposite one that cannot, settle for game – half the loaf.
And what happened at the Pattaya bridge club? 7NT-2, 6♥-2, 4♥+2 twice, 4♥+1 three times.
Dave’s 2nd Column Here is Dave’s second problem on the play of the hand.
♦ J63 ♦ AK4 5♦ pass 6♥ pass
♣ KJ ♣ A10 pass dbl (3) all pass
(1) strong (2) promising a ♥ honour (3) A Lightner double – presumably a ♠ void.
You are East, South leads the ♠K, plan the play.
Dave’s 2nd Column answer Board 20 from Wednesday 25th
Dealer: ♠ - Book Bidding
West ♥ 6322 West North East South
both vul ♦ Q1098 1♠ pass 3♥ (1) pass
♣ Q98642 4♥ (2) pass 4NT pass
♣ KJ ♣ A10 (2) Apparently promising an honour
♠ KQ10876 (3) A Lightner Double – asking for a ♠ lead.
♦ 752 South leads the ♠K, plan the play
This North, an enterprising player, doubled East’s slam in spite of the power auction. His Double was a Lightner Double, directing the opening lead. A Lightner double forbids the lead of a trump or a suit bid by the defenders. Basically, the double asks for an unusual lead. It is often the first suit bid by dummy.
Although well-intentioned, North’s double has backfired. Instead of guiding South’s lead, it alerted East to the winning line of play.
When South led his ♠K, an unsuspecting East would have played the ♠A, North would have ruffed, and the slam would have gone one down. East would have had no place to park his losing ♦.
However, North’s Lightner double should tell East that dummy’s ♠A will be ruffed. Therefore, instead of covering the ♠K, he allows South to hold the trick. After that, the defence can do nothing. East can over-ruff a ♠ continuation and after having drawn trumps he can discard his losing ♦ on the preserved ♠A.
Dave Comment: 6NT is on ice.
And what happened at the Pattaya bridge club? 7NT-1, 7♥*-2, 6NT=, 6♥=twice, 6♥-1 and 4♥+2.
Play Problem Here is a fairly easy play problem that three people got wrong.
West East You are West, declarer in 6NT with no opposition bidding.
♣ A84 ♣ KQ53
Play Problem answer Board 24 from Monday 23rd
Dealer: ♠ J82 Bidding
West ♥ 10753 West North East South
Love all ♦ K1054 1NT pass 6NT (1) all pass
♣ A84 ♣ KQ53
♥ 92 North leads the ♥3. It’s pairs so an over-trick is important if there
♦ 8732 is one. So plan the play for the best chance of an over-trick
♣ 10972 without jeopardizing the contract.
You have eleven top ticks and extra chances in ♦’s and either black suit splitting 3-3, so what should you try first?
Your first priority is to secure your contract and so you should win in hand with the ♥K and play a ♦ to the ♦J. If this loses, you claim the remainder. If the finesse wins, you look for an overtrick by testing both black suits and if either splits 3-3 you have 13 tricks.
And what happened? 6NT+1 five times and 6NT= three times. So it looks like three out of eight did not find the best play.
