Raising partner’s pre-empt.                               Board 1 from Wednesday 14th

Table A:    (1)  What did you bid with this North hand B in this week’s quiz? This single raise is feeble.
                  (2)  A free bid, so showing values.
                  (3)  A bit aggressive.
                  (4)  Having failed to pre-empt to the maximum earlier, North now sacrifices at the six
                        level having given them plenty of bidding space to get there. What’s more, with
                        two very likely defensive tricks in his own hand the sacrifice is dubious.
Table B:     (1)  With four ♠’s, this is my (fairly obvious) answer to question B. Anything can happen, but at least you have made it difficult for them.
                       
The bottom lines:

  1. Do not pre-empt (or raise partner’s pre-empt) and then bid again.
  2. This particular North is well known for doing just that, and in fact his partner specifically mentioned it to him before the session!!

And what happened? Loads of spurious results, with the only N-S score being +50 for 5♦-1.
6♦ has no chance of course.

                        ♣ K4                                      

If you count losers, there are perhaps one in each suit. If the ♥ finesse works that will take care of one, but is there a better chance? If you finesse in ♥’s it may lose and then the defenders will cash another ♠ and probably attack ♦’s and will set up four winners before you have knocked out the ♣A.
So win the ♠ lead and attack ♣’s at trick two by leading the ♣K. If they duck, play another; then they will win the ♣A and cash a ♠. If they then switch to a ♦, win and play a trump to the ♥A and then discard the ♦3 on the ♣J.

And what happened at the Pattaya bridge club? Two declarers passed the test; one with  4♥= and one with 5♥-1. Others went one down in 4♥.

                        ♦ 9876                                     North leads the ♥Q, plan the play.
                        ♣ A763                                  

Declarer has four potential losers, two ♥’s and two ♣’s. But the ♦’s may provide a third trick for a discard as long as the suit breaks no worse that 4-2.
So win the first ♥ and play just one top trump from hand. Then play the two top ♦’s and ruff a third ♦ high. If the suit has broken 3-3, that’s great and you get an overtrick. But North shows out on the third round, so play a second trump to dummy and ruff a fourth ♦. Finally, re-enter dummy with the last trump in order to play the established ♦ to throw a loser from hand.
If you had mistakenly played two rounds of trumps early you would not have an entry to the fifth ♦.

And what happened at the Pattaya bridge club? 6♠-3, 4♠-2 twice, 2♠+1 and three declarers passed the test with 4♠=.

      The bottom lines

  1. Declarer should normally draw trumps unless there is a good reason not too. Often this is a

need to ruff in dummy, but here it is because declarer needs two entries to dummy to set up the ♦’s.

Table A:    (1)  What did you bid with this South hand A in this week’s quiz? Presumably this
                        South meant 3♠ as invitational, I play it as weak after a double.
                  (2)  North decided to pass, I have no idea if he thought partner’s bid was weak or
                        invitational.
Table B:     (1)  This is my answer to question A. The Jordan 2NT, showing a sound raise to 3♠ or better.

  1. Unfortunately North did not understand the bid and passed.

                       
And what happened? 2NT went down, 4♠=  was a popular spots.

The bottom lines:

  1. There is a section on the website about bidding when RHO doubles:

General bridge topics > when RHO doubles.

  1. Basically, if partner opens 1♠ and RHO doubles then:

2♠, 3♠ and 4♠ are all pre-emptive.
Redouble shows 9+ points with no fit for partner.
2NT shows a sound raise to 3♠ or better – The Jordan 2NT (aka Truscott 2NT).
Note that Jacoby 2NT (or Stenberg 2NT) are not played after a double as Jordan 2NT is preferred.

  1. Logically, 2NT cannot be the traditional 11-12 points as with such a hand one would redouble.

 

 


 

Bidding Quiz Answers  

Hand A:   2NT, Showing a sound raise to 3♠ or better. This is the Jordan (aka Truscott) 2NT.
                  The logic behind this bid is that with a natural 2NT one would redouble; also, all ♠
                  bids are best played as pre-emptive. So use the ‘spare’ 2NT as a sound raise.
Hand B:    4♠, raise partner’s pre-empt to the limit and do not bid again. Anything less makes it easy for the opponents, and with four trumps and a void, 4♠ may                   even make (it did at one table, or at least 10 tricks were made in a silly 6♠ doubled). I guess that an immediate 5♠ is an alternative.

 

Bidding Sequence Quiz            
                 
C      1♥     dbl     redbl            Redouble shows 9+ points with a lack of support for partner’s suit

D      1♥     dbl     3♥                This is best played as pre-emptive.

E      1♥     dbl     4♥                This is also best played as pre-emptive.

F       1♥     dbl     2NT             This is the Jordan (aka Truscott) 2NT.  Since with a balanced
                                                11-12 points you would re-double, this bid is spare and so it is
                                                used to show a sound raise to three or more of partner’s suit.

G      1♣    dbl     redbl    1♠        (a) All doubles after a re-double are for penalties
         ? (1)                                     (b) pass is forcing. Your side has the majority of points and
                                                           partner will either double (for penalties) or bid.
