Gordon, could you number your responses? I'd like to compare, but it's giving me too much of a headache in their current format.

I just want to respond "too hard" to a lot of these

[PhantomSac]

OK, so those pesky opponents have dared to open the bidding and raise to game. Well, are you going to bid, or are you too scared of going for a number?

 

All hands are from top-level play.If the hand has an L after it, the opening was limited, which means the raise might not be preemptive.

[cherdano]

Well, we would definitely be compatible partners lol.

:)

(You are assuming I am compatible with myself. Given that Philking thinks I might not agree with myself, that might not be a safe assumption.)

[helene_t]

What about writing a book called "know your partner's style" with problems like this? I think that it could be useful for partnerships if both took a number of such quizes and compared their answers. Not about finding out who makes the best guesses but about knowing how serious you have to take partner's bids.

[gwnn]

I'm not far (19/23 if I'm counting correctly) from PhantomSac either. I consider that a success, regardless of what Simon Cowell will think.

I think 21 is the hardest (all 3 options are in the mix) followed by 18. I also do not understand passing 3 but bidding on 15, so am hoping to learn something important in due course! Another point is how PK calculates his scores. With widely different approaches in 4th seat, it seems clear that different approaches in 6th will also be used and taking account of that is not going to be easy!

[gordontd]

It's time for the results. I have decided to use aggregate scoring, so you are scoring against each other rather than with the other table. It looks as though anything under -3000 is a cracking total.

 

But first a few awards ....

 

The "4♥ is a transfer to 4♠" award goes to Jinsky and Eagles123. They both stepped into the breach 14 times. Quite remarkable given that the lowest number was 4. Eagles also had the equal fewest passes with gordontd.

 

The "flexible double" award goes to WesleyC, who kept his options open on 12 hands.

 

And the "take a plus" award goes to Remnart, who resisted temptation on 14 hands.

 

Now the scores ....

 

1. ♠AQT73♥43♦K7♣KQJ2. Pass -650, 4S -100, Dbl -100

 

The opponents can make 5♥ on a finesse, but in practice they sold to 4♠, and you will get there via an overcall or a double.

 

2. ♠KQT75♥54♦AKT2♣K5. Pass +50, 4S +450, Dbl +450

 

Again, either positive action gets you to 4♠, so the passers lose out again.

 

3. ♠AQJ943♥4♦973♣T94. Pass -650, 4S -1100

 

In practice, the 4♠ overcall led to -1400 in 5♠, but that's because partner had not bought the best-selling new bridge book "Know your partner's overcall style," and competed over 5♥ with ♠T85♥J92♦KQJ5♣K83. I have credited partner with a pass, but by the same token LHO did not have an automatic 5♥ bid, so I have gone with a compromise score of -1100.

 

4. ♠KT652♥-♦AK642♣A94. 4S +200, Dbl +200

 

Whichever action you take, you should go plus against 5♥.

 

5. ♠Q76♥Q63♦AK84♣AK4. Pass +100, Dbl -200

 

I think pass is obvious. Your hand screams defence, and you know partner will remove a double. Partner was very suitable: ♠KJT93♥J5♦9♣J8653, SO 4♠ had a play, but defending was right this time.

 

6. ♠A875♥6♦AKJ74♣K94. Pass -420, Dbl -690 (I am assuming Gnasher's 4S overcall is a typo)

 

Partner had balanced junk on this occasion.

 

7. ♠653♥QJ3♦AKJT976♣-. Pass +50, 5D +300

 

Ron Smith passed. It's not clear how well you do if you overcall. Partner has ♠KQT♥2♦Q8432♣A642, but if he has read "Know your partner's overcall style," he will take the money over 5♥.

 

8. ♠AK74♥AT♦JT5♣AK84. Pass -620, Dbl -200

 

Taking the money does not work this time. Declarer should make 4♥. In practice it was butchered, but I am not crediting the passers with a plus, since he went down on a somewhat different auction. Double gets you to 4♠ one off.

 

9. ♠AK953♥K8♦82♣AKT8. Pass -420, 4S +100, Dbl +100

 

Any positive action pushes them to 5♥ one off.

 

10. ♠AKJ973♥2♦T742♣J4. Pass -450, 4S -1100

 

4♠ gets stretchered. I thought I liked overcalling 4♠ as much as anybody before this thread, but I would leave this one alone. We have defence, and you have to respect the vulnerability a bit.

 

11. ♠A53♥T♦AJT953♣A87. Pass -420, 5D -800, Dbl -800

 

This looks like a defensive hand. It's possible that double leads to -590, but only if partner stands it with ♠T864♥93♦Q76♣T643. You might end up being brutalised in 4♠.

 

12. ♠K87432♥-♦A4♣T7643. Pass +50, 4S +420

 

4♠ was an extremely popular choice amogst the quizzers, and Versace also chose that action at the table.

 

13. ♠AK864♥Q72♦A72♣43. Pass +100, 4S -100

 

You catch partner with five spades and a few bits and pieces, yet bidding was still wrong. They could have made 4♥, but with no real clues, declarer wandered a couple off.

 

14. ♠AQJ72♥Q♦T2♣86543. Pass -450, 4S -100

 

The points go to the brave here. Trendafilov passed at the table.

 

15. ♠KQ9874♥8♦J6♣AK75. 4S -800

 

The better your hand, the worse the dummy will be. :(

 

16. ♠KT9♥-♦Q9754♣AK764. Pass -420, 4NT +50, Dbl +450

 

I have sympathy for the 4NT bidders. Double works because partner has five spades and a hand that might of overcalled. The oppo ended up letting through 5♠ on a misdefence.

 

17. ♠AQJ9542♥T3♦T98♣2. Pass -650, 4S -500

 

The overcall wins a few imps. It looks pretty borderline to me.

 

18. ♠AJ943♥42♦AKJ6♣Q4. Pass -420, 4S -200, Dbl -590

 

Both tables doubled and conceded 590. I think the 4♠ overcallers would have done very well. Although it could be double for two down, I don't think it would.

 

19. ♠KQ74♥4♦63♣AKT976. Pass -650, 4S -500, 5C -500, Dbl -100

 

Double gets you to 4♠ one off, but comes with risks of its own. I presume all the 4♠ overcallers plan on running to 5♣, and that goes for 500 because spades are 4-1.

 

20. ♠AK943♥K2♦JT9842♣-. Pass +100, 4S +500, Dbl +300

 

After a 4♠ overcall, a wild auction in which both sides diagnosed a double fit ended in 7♣X down three despite 4♠ being the limit. Four hearts is down two on club ruffs.

 

21. ♠KT743♥J♦QT♣AQJ84. Pass -420, 4S -200, Dbl -200

 

Helgemo passed. In another match Fitzgibbon doubled and got to 4♠.

 

22. ♠AK732♥Q♦75♣AKT98. Dbl +100, 4S -200

 

You go plus if you double, but at the colours I think 4♠ is right. Levin overcalled 4♠, but ran to 5♣ when it went p-p-x, so shelled out 500.

 

23. ♠AT72♥2♦KQ6♣KQT63. Pass +50, Dbl +300

 

Double looks clear, because you have quite a lot of offensive potential, and there is usually more to gain than lose. 4♠ was booked to fail, but the opponents misjudged at multiple tables and went on to 5♥.
