Scoring: IMP

Oppos bid 2♥(weak) 4♥. Your pard lead the ♦7 (showing 2/4 cards). What is your plan, if any ? (strong oppos).

EDIT: pard lead x(x)xx, xx(x), (x)x so you probably know pard has 4 small.

mmm, switch to ♣10?

this way declarer will have 9 tricks and will need only one from spades, hence he is able to missguess. If declarer has singleton spade he is out of time to make it anyway.

How can that be 4th best ? Rule-of-eleven says that there would only be 4 cards in the other 3 hands that would be higher than pard's 7. You can see 5 higher.
That means pard has probably led 2nd highest from 3.

That puts Declarer with 6h, 4d and only 3 cards in the black suits.

That's better.

Take the first trick and lead back another ♦ . Declarer may put you on a doubleton. Sooo, he is going to lead trumps rather than clear that 3rd high ♦ off the board.

Having that remaining high ♦ on the board is going to be a liabilty for Declarer in the end game. [ Either you are partner will be able to "safely" lead the 3rd ♦ when you are in with a trick... so you (especially) are not endplayed.

You are going to duck the 1st trump trick, win the 2nd and lead a 3rd ♥.

Declarer is going to lead a low ♠ and put in the Jack.
You DUCK ! !
How does he get back to hand to repeat the finesse ?
You should be able to get 2 black suit tricks no matter if
he started with 1/3 , 2/2, or 3/1.

Why wouldn't declarer use his entries to hand more efficiently than this?

Won't he be in hand twice to lead spades? What is the rush to draw trump?

Giving up the diamond ruff to the supposed doubleton? I like his answer.

Fluffys answer is cool but I would just play back a diamond and hope they are worried about a diamond ruff. Maybe they should know they're 4-3, still don't really understand our leads.

Maybe declarer won't either, so that makes a diamond lead even better...

Scoring: IMP

West hand was :
Scoring: IMP


South gave it no second thought and played a diamond back. Maybe he hoped declarer would misread something (NB: the only one who could have a diamond doubleton here was North, and as those leads are very common in France, West would not have missed that) or do something silly in the Blacks. He scored a quick 10 tricks.

I liked fluffy's answer : I didnot think about that, and actually it might work if declarer was 2632 missing the ♠Q.

In the postmortem as it seemed unbeatable, I was wondering if South could have chosen another imaginative line of defense : Play back the ♠9 !?

North of course will duck (he doesn't have the Ace after all ;)), and if West is 3631, he may imagine South has played a doubleton back (North would duck with ♠Axxxx, knowing West didnot open 2♥ with ♠Qxxx, definitely not the local style). If West is convinced that Spades are indeed 5-2, he may play the ♠Q, and finesse the ♣K hoping to discard a Spade on the ♣Ace.

We'll never know if this idea would have worked. Playing ♠9 also is sometimes ridiculous when West is 1633 (less likely than 3631). I was really wondering the probability declarer would choose to finesse Clubs on the actual layout. Would you have ?

No amount of subterfuge is going to work without the ♠Q on our side.
