♣ 4

Table A: (1) I guess it’s up to you if you wish to double or bid the good ♣ suit, this double looks OK to me.

(2) 2♣ (non-forcing) is an alternative.

Table B: (1) This West chose to bid 2♣.

(2) What did you bid with this North hand A in this week’s quiz? I too would pass, expecting partner to re-open with a double which I would obviously pass.

(3) What did you bid with this South hand C in this week’s quiz? I think that double is ‘automatic’. This South chose to bid; but if you really want to bid, then bid 3♦.

(4) North assumed that South had a weak ♦ hand and so sensibly passed.

And what happened? 3NT+1 four times, 3NT= and 2♦+1.

The bottom line:-

- Remember the ‘automatic’ re-opening double when playing negative doubles.

♥ A843

♣ 105

Table A: (1) What did you bid with this West hand B in this week’s quiz? Of course you want to double 1♠ for penalties but playing negative doubles you cannot. And if you cannot rely on partner to re-open with a double then I guess you have to bid 1NT?

Table B: (1) This West had confidence in his partner who almost always re-opens with a double, so no problem, pass. This is most certainly my answer to question B.

(2) What did you bid with this North hand D in this week’s quiz? Double is ‘automatic’.

(3) As planned.

And what happened? 4♠(W)*-1, 1♠(S)*-1, 1NT+2, 3♦=, 3NT= and 1NT=.

The bottom line:-

- Remember the ‘automatic’ re-opening double when playing negative doubles.

(1) What did you bid with this East hand E in this week’s quiz? I don’t like this overcall at the two level with such a weak suit. If you want to bid then I prefer double but pass is certainly an alternative.

(2) What did you bid with this South hand F in this week’s quiz? With ♠ shortage I agree with Dave’s pass – looking for a penalty.

(3) What did you bid with this North hand G in this week’s quiz? Thomas bid an ‘automatic’ double, but I suspect that many will bid 2♥ or pass and miss the penalty.

(4) I would pass, but as it happens there is a ♣ fit.

And what happened? 2♦* would have gone -3, 3♣* went -2 for 300 to N-S and a complete top. At two other tables it was 2♦-3 twice but undoubled.

The bottom line:-

- Remember the ‘automatic’ re-opening double when playing negative doubles; but this is perhaps not wise with this particular North hand.

♥ J104 West leads the ♥8 and East takes the ♥Q and ♥A and a

♦ AQ third ♥, expecting West to ruff, but dummy’s ♥K wins.

♣ A94 What critical play must East prepare to make?

After South won the third ♥ in dummy, he led a ♣. East was disappointed that partner had not ruffed a ♥ and he followed with the ♣5.

South took the ♣A, cashed two trumps and two ♦’s and led a ♣. East won with the ♣K and had to lead a red card, giving declarer a ruff and discard and thus his contract.

South played the hand well, but East had no excuse. When dummy leads a ♣ at the fourth trick, East must put up the ♣K, a play that can’t cost. South’s partial elimination will now fail as West can take two ♣ tricks.

And what happened at the Pattaya bridge club? 3NT+1, 2♠+1, 5♠-2 and 4♠-1 three times.

Dave’s 2^nd Column Here is Dave’s 2^nd problem on declarer play.

♠ 84 N ♠ AQJ (1) With top cards and two tens, North considered

♥ J74 W E ♥ Q965 the hand too good for 1NT.

♣ A7642 East has the ♠AQJ on a low ♥ lead?

This is how declarer played: ♥A, ♥K, low ♥ ruffed, cross to ♦A, ruff the last ♥ with the ♠10, cross to the ♦K, ruff the ♦2, leaving this position:

♠ K953

♥ - Declarer then ducked a ♣. East returned a ♣ which

♣ Q86

Table A: (1) What did you bid with this South hand H in this week’s quiz? This is wrong of course because it is not forcing.

(2) With a lot of bidding space consumed and little to go on, opener elects to go for the NoTrump game.,

Table B: (1) A direct 4♥ is possible, but this bid (4^th suit forcing) is better and is Hans Vickman’s answer to question H.

(3) Showing a ♦ stop.

(4) And this is how you make the 3♥ bid forcing (go via 4^th suit).

(5) North is in a better position than at (2) above as partner declined to bid 3NT

at (4), thus he chose the far superior ♥ game.

And what happened? 4♥= three times, 3NT= twice and one adjusted score.

Bidding Quiz Answers

Hand A: Pass, and pass partner’s presumed re-opening double.

Hand B: Pass, and pass partner’s presumed re-opening double.

Hand C: Double. Partner probably has a penalty hand and with great top cards you are happy to defend.

Hand D: Double. Partner probably has a penalty hand and if he has you are prepared to defend.

Hand E: Double. It would be nice to have four ♥’s, but these are a decent three. If you play that a double would promise 4 ♥’s then the alternative is pass. The one bid I don’t like (which I suspect that the majority will make?) is 2♦, this suit is not good enough for a two-level overcall.

Hand F: Pass, and pass partner’s presumed re-opening double.

Hand G: Double? This is not as clear-cut as Hands C&D because partner may well not have a penalty hand and you do not want to hear 3♣. It may well be more prudent to pass. I would not bid 2♥, I prefer pass or double.

Hand H: 3♦ or 4♥. You cannot bid 3♥ as that id not forcing, so bid the 4^th suit and then 3♥ forcing. The simple alternative is to simply bid 4♥ as that is presumably where you want to play even opposite a void.

Bidding Sequence Quiz Answer

J 1♣ pass 1♦ pass

1♥

(a) The 1♥ rebid is not forcing in Standard American or Acol. However, opener may have up to 18 points or so and the bid is rarely passed. But if responder has a very weak hand and no tolerance for opener’s first bid suit and he only bid out of fright, then a pass of the rebid is clearly acceptable. Note that in some systems (e.g. the Swedish system played by Janne & Co.) the 1♥ bid is indeed forcing.

(b) In Standard American opener has three + ♣’s, possibly two if playing a short ♣ and not playing Walsh.

(c) In Acol the opener usually has five ♣’s. Can be four if say 4414 or similar, but that is just about the only shape where I would open a 4-card minor rather than a 4-card major when playing Acol; in modern Acol you open a 4-card major rather than a 4-card minor.

K 1♣ pass 1♥ pass 3♥ is invitational. If you want to make a forcing 3♥ bid, then

1♠ pass 3♥ bid 2♦ (4^th suit) followed by 3♥.
