Paul’s Column

Monday, Feb. 15 there were 3 boards I found interesting and instructive.

If a little knowledge is a dangerous thing, a LOT of knowledge can be a CATASTROPHE!

It isn’t fair for me to be critical of anyone else’s bids or plays unless I tell this tale about myself. On board 16, NV vs Vul, I was North. A routine auction led to me declaring 3NT.

North

♠AKQ6

♥109

♦AKJ109

♣Q3

West East

♠542 ♠987

♥76 ♥QJ85

♦76543 ♦Q2

♣AK2 ♣J987

South

♠J103

♥AK432

♦8

♣10654

The defense began with 3 rounds of clubs and East continued with a 4^th club, North pitching 2 diamonds and on the 4^th club West pitching a discouraging heart. 4 rounds of spades followed with both West and East parting with a diamond. Then the A, K of hearts putting the lead in dummy with these cards remaining:

North

♦AKJ

West East

♦765 ♥QJ

♦Q

South

♥43

♦8

With a complete count on the opposing distribution it was now easy to work out that West had 3 diamonds left and East had only 1. A 75% probability that the finesse was working, and this is matchpoints after all, so a diamond to the J. THE ROOF FELL IN! -100 when everyone else made +430!!

If you double an artificial bid for the lead you had better be sure you can beat that contract.

On board 29, with both vulnerable, the layout was this:

North

♠J963

♥AQ53

♦Q10

♣752

West East

♠Q102 ♠875

♥K1097 ♥842

♦J8653 ♦72

♣8 ♣AQJ94

South(A)

♠AK4

♥J6

♦AK94

♣K1063

What did you open with this South hand A in this week’s quiz? This South evaluated his balanced 18 hcp with 7 in a 3-card suit and 1 in a doubleton as worth only 17, correctly in my opinion. He opened 1NT, West passed, and North bid 2C, Stayman. East saw a chance to get his side off to a good lead and doubled. South was about to bid 2D, but then thought better of it. He REDOUBLED showing 4 or 5 good clubs and, usually, a maximum opener. West turned 3 different shades of green before passing, and North happily passed holding 3 clubs and some useful cards. The usual contract of 3NT scored +630 or +600 at all the other tables. 2C** also took 10 tricks, but for +1560! At IMPs I’d hate to bring a result like that to my teammates!

About the Ogust convention

Terry was quite mistaken in his claim in news-sheet 380 about Ogust not being popular in America.  Have you actually ever PLAYED there??

Terry Answer. No – but I have only met two Americans at the club who played Ogust. Also, if you look at the definition of the 2NT response to a weak two on the pre-printed ACBL SAYC convention cards it clearly says “2NT – if maximum requests a feature”.

Also, the recent book ‘Standard bidding with SAYC’ by Downey and Pomar, says on page 86 – “There are several systems that utilize this 2NT forcing response. In the most common version – and the one that is standard to SAYC – 2NT asks partner for a feature. A feature is defined as an outside ace or a protected king or queen”.

I believe that Paul means that Ogust is popular with the more experienced players in America.

Making a flawed take out double can be dangerous

Board 13 was as follows, all vulnerable:

North

♠6

♥AK8765

♦J63

♣876

West East

♠J108753 ♠KQ42

♥VOID ♥J1094

♦Q954 ♦K108

♣1042 ♣K9

South

♠A9

♥Q32

♦A72

♣AQJ53

After North opened 2H East inquired what that was. Upon being informed it was a normal “weak” 2 opening he decided to make a take-out double. Let’s look at the flaws: A) heart length in a hand far too weak to bid NT next, B) under-strength with an ace-less balanced 12 count to act directly on the 2 level vulnerable, and C) it pinpoints the defender’s high cards should the opposing side declare. If his side owned the contract his partner should be able to act. What was he intending to do over a 3C response by his partner?? The auction proceeded REDOUBLE by South, 3S by West, P, P, FIVE hearts by South. What is 5 hearts? Some play it as asking for second round control of the opponents suit to bid 6, some play it as asking for trump quality to bid 6 … but whatever it was North had it!

East naturally failed to find the killing diamond lead and N/S scored up +1430, the only pair to bid slam. South had correctly assumed the club king would be well placed (See News Sheet 366 “Card Placement by Assumption”) and with his good trump support and a side suit source of tricks as well as first round controls in S and D he issued the slam invitation. Most Souths either bid 4H directly or went through an asking call of 2NT first.

< End of Paul’s Column >

Dave’s Column Here is Dave’s first input on the play of the hand.

West East West North East South

♠ Q4 ♠ K875 - 1♦ dbl pass

♥ A543 ♥ QJ96 2♥ pass 4♥ all pass

♦ 752 ♦ A4

♣ KQ104 ♣ AJ2

You are West, declarer in 4♥, and North leads the ♦K. You win in dummy with the ♦A and South encourages. How do you play the trump suit?

Dave’s Column answer Board 5 from Wednesday 24^th

Dealer: ♠ A93 Book Bidding

North ♥ K7 West(B) North East South

N-S vul ♦ KQJ986 - 1♦ dbl pass

♣ 86 2♥ (1) pass 4♥ all pass

♠ Q4 N ♠ K875 (1) What did you bid with this West hand B in

♥ A543 W E ♥ QJ96 this week’s quiz? 1♥ is wrong as the hand is

♦ 752 S ♦ A4 too good and this 2♥ bid is correct.

♣ KQ104 ♣ AJ2 1♥ would show around 0-7 HCP’s and this

♠ J1062 jump to 2♥ shows about 8-11.

♥ 1082

♦ 103 .

♣ 9753

So you are West declaring 4♥ and North leads the ♦K. You win in dummy with the ♦A and South encourages. How should you continue?

There will be almost certainly one trump loser and the contract will depend upon avoiding a second one. The correct play is a low trump to the ♥A and a low ♥ towards dummy. On the auction, North rates to hold the ♥K, and there is no advantage in running the ♥Q, which would lose not only to a singleton ♥K but also to the actual unexceptional layout. North would take the ♥Q with the ♥K and lead two more ♦’s. It would not matter if declarer ruffed with the ♥J or a lower card – South would always score a second trump trick.

By playing ♥A and another ♥ declarer avoids a rather ignominious defeat. By preserving the ♥QJ in dummy, declarer can ruff the third ♦ and draw South’s ♥10 with dummy’s remaining trump honour.

And what happened at the Pattaya bridge club? 4♥= four times, 2♥+3, 2♥+2, 2♣+2 and 3NT-3.

Dave’s 2^nd Column Here is Dave’s second problem on the play of the hand.

North South West North East South

♠ KQJ87 ♠ 92 - - 1♥ 2♣

♥ 64 ♥ K83 pass 2♠ pass 3NT

♦ J1062 ♦ AQ all pass

♣ K10 ♣ AQJ972

You are South and arrive in a very good 3NT after East opens the biding in first seat. West leads a ♥ and East plays the ♥Q. East must have the ♥A so you could duck but there’s nothing to gain by doing so, and so you take the trick with the ♥K. It looks as though you need the ♦ finesse through the opening bidder for your 9^th trick. Is that so?

Dave’s 2^nd Column answer Board 6 from Wednesday 24^th

Dealer: ♠ KQJ87 Book Bidding

East ♥ 64 West North East South

E-W vul ♦ J1062 - - 1♥ 2♣

♣ K10 pass 2♠ pass 3NT

all pass

♠ 10653 N ♠ A4

♥ 952 W E ♥ AQJ107

♦ K S ♦ 987543

♣ 86543 ♣ -

♠ 92

♥ K83 The remarkable thing about this deal is that if the ♦K is

♦ AQ onside, you don’t need to go to dummy to take the finesse

♣ AQJ972 – it will take care of itself.

East is marked with the ♠A, which he must hold, and he must keep four ♥ winners, else declarer can concede a ♠. So run your six ♣’s and see what happens. On this layout East, who has no ♣’s at all, discards a ♠ and … five ♦’s. His last six cards must be the ♠A, four ♥ winners and one ♦. If it’s the ♦K it will fall under the ♦A. If it’s not the ♦K then it must be singleton in West’s hand.

Although you could not envisage East’s distribution as 2560 to bring about this spectacular ending, it should have been possible to appreciate that taking the ♦ finesse early could not gain and could only lose. The hand was originally played in this way by France’s Venice cup and World Mixed teams champ, Catherine d’Ovidio, in a major French tournament.

And what happened at the Pattaya bridge club? Not surprisingly, nobody ended up in ♠’s. 4♥-3, 4♥-2 twice, 3NT-1 three times, 3♦+2 and 3NT=.

Bidding Quiz Answers

Hand A: 1NT – or 1♣/♦? 1NT is the opening bid made by Janne and agreed with by Paul Quodomine in his column. I (Terry) am not convinced by Paul’s explanation as to why the hand should be de-valued to 17. I have often stated that AK doubleton is a ‘poor’ 7 points but in my opinion that does not apply to AKx which is a good 7 points. Also, I like both of the 4-card suits and the ♣10 is significant in a 4-card suit. I disagree with our two experts here and suggest 1♣ or 1♦, according to style, with a 2NT rebid if partner responds 1♥. In my opinion this hand is too good for a 1NT opening – and I am usually the first to agree with hand evaluation when necessary and will open 1NT with a good 14 or a poor 18; I do not consider this a poor 18 and the excellent result obtained is no excuse for the opening under-bid.

Hand B: 2♥, showing around 8-11 points. 1♥ is wrong as it shows only about 0-7 points.

Bidding Sequence Quiz Answer

C 2♥ pass 2NT This 2NT response to a weak two is generally played as forcing and the meaning is up to partnership agreement. Ogust and feature ask are popular treatments.
