Both in 4♥. Partner was apologetic when he went down, but I thought he had played for the best chance given the bidding. At our table North overcalled 1♠. At the other table North overcalled 2♠. Was this why we lost 14 imps?

Certainly the14th IMP is avoidable as ruffing last spade in hand to shorten our trumps is a really bad move, but other that that, richard tlegrahped the ♣Q position on the other table, you don't really have much blame.

[andrei]

Playing Q♠ at trick 2 was not a smart move.
If first 4 tricks are:

♦: A 7 Q 3
♠: A 3 9 7
♠: J 4 4(♥) Q
♦: K 9 2 3(♥)

The position now is:

---

cross in hand with a trump, ruff 10♦ with A♥, draw trumps
now N is known to have been 6223
play remaining trumps, N needs to keep 2 spades and discard 1 club and you have the rest regardless where Q♣ is.

Show-up

What Andrei said, except he meant spade king at trick 3 not spade queen at trick 2.

When west leads 9♣ North shouldn't cover with 10. on the hand that made, gives declarer a winning option he wasn't going to take.

I really meant Q♠ at trick 2

Spades were
N:AJTxxx
W:Qx E:Kxxx
S:x

When, at trick 2, N played A♠, declarer played Q♠ from hand instead of a small one, probably trying to convince N that he has a singleton. It did not work

At our table I would play different than Aaron did, risking to go down more to get more info about their hand.

Richard was known to hold 6♠+2♥ at the time when Aaron cleared last trump.

Now ruff a diamond and ruff your own good ♠ K in hand to be able to ruff 3rd ♦ so you can see how many diamonds Richard held. He will see Richard's original shape is 6223. And due AJ ♠+A ♦ I'd play for Qx ♣ and play Richard for xxx/ Txx club as Gonzalo said. However if he finds out that Richard has only 2 clubs, (if Richard followed 3rd ♦) then I'd play Richard for Tx ♣.

Thanks for pointing out the show-up squeeze Andrei

Yes the crucial difference between the 2 auctions is that Richard overcalled 2♠ (assumed weak) whereas Csaba overcalled 1♠ (Assumed less limited). I think Timo is saying that Richard is known to hold a 3 card club suit and therefore in isolation is more likely to hold the Q. However this would give him 11HCP with 2 aces and even with Richard's pre-empting style, this is unlikely.

No, I am not saying that at all. I said due to AJ♠ and A♦ I'd play for Qx club (Qx with his pd, not Richard)

I am saying that after ruffing diamonds, IF Richard is known to hold 3 card clubs, then I would play him for xxx or Txx (Cash AK). But after ruffing diamonds, IF Richard follows all of them then he is known to hold xx or Tx. Since I can not do anything when he holds xx, I would play him for Tx. Play small to the K and then play J from dummy.

At our table, squeeze was never an option. Defense started with ♠A and spade ruff, ♦ A and 3rd spade played. We had to guess clubs. Aaron made a successful blind guess, where he could improve his chances by making a more informed play.

Oh I see what you are getting at. However, making this discovery play with A985 opposite ♣KJ76, you happen to be on lead from the KJ76. So presumably you would just bang down the King and then run the Jack. Running the Jack first would be equal, although there are some even with Q10x who might not cover.

Yes I will be in dummy, but it does not matter. As long as I know that Richard can not have Q I will just cash ♣K as you said. What I will play next (J or small) depends on how many club I think N has. And I will know it by discovery play.

I would pass with the West hand and set 2♠.
Problem solved.
