Scoring: IMP

W　　 N　　 E　　 S
pass 2NT(1) 3S pass
4S Pass All

(1): both minors preempt

You sit south and lead your ♦ singleton, on North's Q the declarer puts A. Then he plays ♣A and three round of Club, discard a ♥J in the third.

I guess everyone will ruff with ♠3. Now the question: what's next?

This quiz consists of several questions. I'll go on after i get at least one winning reply. And i'm sure it will come here soon enough

Declarer has AK10xx J AJxxx Ax.

I play a high trump, ruff the diamond continuation, and play another trump. Declarer makes one diamond, two clubs, five trumps in hand, and one ruff in dummy.

... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn

That seems perfectly rational.

soon enough. and perfect for the first question! thanks qnasher. However, that's not the untimate answer.

you return a high trump, pd follows 7. Now it's almost a double-dummy situation: declarer holds a 5152 shape.

what would you play if declarers continue with

(1) ♦J ?
(2) ♦T ?
(3) ♦9 ?

I find it a ridiculous lead...

OK - I didn't get this quite right.

Suppose that declarer's diamonds are AJ1032. If he leads a high one I should ruff and play a trump; if he leads a low one I should let partner win cheaply, then ruff in on the third round of diamonds to play a trump. (Equivalently, partner can play a club back, declarer discards a diamond, and I ruff and return a trump.)

If declarer has AJ1092, we can't beat it, so if he leads the 9 I have to play him for AJ987 or worse.

So, if declarer leads the J or 10 I ruff; if he leads anything else I discard.

... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn

Tks and congratulations qnasher. I'm impressed by the promptness of your reply.

This board was played during a team match at BBO and South is a Romania star player. Personally i don't think Diamond lead so unacceptable, but at the six round when I played a DJ he did toss a heart carelessly, suddenly the contract became unbeatable.

Maybe for internet bridge that's totally normal. Anyway, if it's not for a quiz, a lot of expert players at the table might fail to realize that's the key moment for defence. I did hold AJTxx by the way.
