Table A:†††† (1)What did you bid with this East hand A in this weekís quiz? This 2 is the only option if you do not play something like Jacoby 2NT, Swiss or Steenberg.

(2)   Apparently meant as a cue bid agreeing ís. I would play it as a cue bid agreeing ís.

(3)   This was some kind of Blackwood I believe.

(4)   Two keycards; quite why West thought that East had agreed ís I do not know.

(5)   Presumably East was playing normal Blackwood (or RKCB for ís?). Either way this auction is a total shambles, from the second bid onwards, by two of the clubs better players.

Table B:†††† (2)Most of the club play 2NT here as agreeing ís; either Jacoby 2NT or Steenberg.

(6)   This shows a minimal hand playing Jacoby 2NT. Playing Steenberg then 3 would show a minimum I believe.

(7)   Opposite a minimum East simply signs off in ís. Note that if East had a better hand then ís are agreed and 4NT would definitely be RKCB for ís.

††††††††††††††††††††††††††††††††††††††††††††††††††††††††††

And what happened? Everybody was in 4+1 except for the two in 6 who both went down.

The bottom lines: -

-         In my opinion it really is essential for a pair well past the beginnerís stage to have a forcing raise of partnerís 1/ opening available. Jacoby 2NT is the obvious choice but there are other options.

-         If you do not have this simple tool in your bidding armory then you will get into mix-ups like at Table A when responder has a good hand in support of partnerís major Ė how can he show good support and later bid RKCB with ís as trumps (as necessary here as the K is an important card) if the auction starts 1 - 2?

8 ever 9 never or restricted choice?†††††††††††††††††† Board 13 from Monday 26th††

 

We all know that playing for the drop with 4 cards including the queen missing is slightly with the odds; but what when missing the QJ and one of them appearing on the first round?

KQ10873†††††††

So, onto the play. The lead is ruffed in dummy and you lead the A to the 4, 2 and the Q from South. Do you now play for an original 2-2 split or do you finesse?

If you ignore the inferences from the bidding you should finesse. This is a classic case of restricted choice (which is a rather complex mathematical topic which is beyond the scope of these news sheets).†††††††††††††††††††††††††††††

††††††††††††††††††††††††††††††††††††††††††††††††††††††††††

And what happened? Only this E-W pair played in ís; at every other table the contract was either 4 or 5 (doubled or undoubled) by N-S. 5 by East made for a complete top when declarer took the correct view in ís.

The bottom lines: -

-         Normally when there are just 4 cards out including the queen, then the odds are to play for the drop. But when you are missing the queen and the jack and one of these appears on the first round, then Restricted Choice applies and you should finesse. This is all explained in detail on the website:

Table A:†††† (1)What did you bid with this South hand B in this weekís quiz? This 5 is far too unilateral for me.

Table B:†††† (1)This player found a much better bid Ė he apparently thought that 4NT was Unusual, for the minors. Anyway it worked well.

(2)   I guess that this is an exception to bidding again having pre-empted. After Southís 4NT bid N-S are forced to reach a making game or slam and this is a good save at this vulnerability. Note that West cannot open 5 as that is a strong bid inviting slam when partner has a top honour.

††††††††††††††††††††††††††††††††††††††††

And what happened? Unfortunately for West at table B; 5*, which is a good save, scored a complete bottom as no N-S in the room found a making game! Results were 5*-3, 4-2, 5-1 three times and 5*-2. Nobody found the fit.

The bottom lines: -

-         You have to agree what bids mean over a 4 opening. Some play double as penalties and others as a three-suit take out (which partner can of course convert to penalties if he wishes). This then leaves 4NT available as a two-suit (any two suits) take out.

-         Using this treatment, South should bid 4NT and North, with great support for either red suit can bid 6 (pass or correct to 6 if partner has ís and ís). Chickens could bid a simple 5 which would have earned a top on the day.

South led the 2 to the K and at the table East won with the A. He cashed the trump ace, led a low trump to dummyís 9 and played a low from dummy. East won Northís J with the A and played another , losing to Northís Q. North then led a to Southís Q and South had an easy shift to the 9. The finesse lost and the game was defeated; East losing 1 , 2 ís and 1 .

Would East have made the game had he refused to win the J? Close, but not close enough. North would have led a to South for a switch before the ís were established, leading to the same one down.

To make the game, East must refuse to win Northís K at trick one. If North returns a then East wins, draws trumps and leads a from dummy. When North plays the J East ducks and the defence is finished. If South overtakes to lead a then East loses only one trick. And if North continues with his Q the East wins and leads a 3rd to establish a winner, eliminating the need for a finesse.

And what happened at the Pattaya Bridge Club? 4+2 twice, 4= twice, 5-1, 5-2, 2+1 and 3+1 and 4 by North *-3. Note that 4 by N-S is a good save and that it pushed the opponents into 5 going down on two occasions.

 

Bidding Quiz Answers

 

Hand A:††† 2NT, the Jacoby 2NT (or some Scandinavian variant if you wish). If you start with 2 you will probably get in a mess as you may want to later investigate slam and need to have ís agreed in order to use RKCB.

Hand B:††† 4NT, take-out. But this does depend upon your agreements as explained below.I do not like 5 which is too unilateral with such a poor suit and I donít like double if you play it as penalties.

The 4 opening leaves you short of room and you have to agree what double and 4NT mean:

1)      One treatment that I read is that double is penalties and 4NT a 3-suited take-out.

2)      However, Iím not so keen on this and prefer double as a 3-suited take-out which is reasonably happy to be passed for penalties; and 4NT as a two-suited take-out.
