Hey cool. Isn't this one of those hands where if they lead a club against 4 you should duck it?

Hmm, maybe you also check. I do not see any intricateness. Anyway please count me as an amateur who derives satisfaction "trying" to solve double dummy problems in long years.

Say led vs 4 :
A, I think then best move is another and ruff at table.
T now. At first sight seems worths to cover with A. Another . And clears trumps. Declarer pitches a at table.
How about another trump?
I think East pitches a low . Declarer also pitches a low . Surely West may join to th fiesta.
A heart to Ace then diamonds.
Did I count wrong ? West and East each seperately restricted to get a trick. So +1.

Say led vs 4 :
West cashes A 2nd round, exists with another . Declarer pulls last trump. All discards low .
I think declarer can safely play A and another . Say West allows to East win this trick.
I do not see any damage for declarer to any defense. No matter or switched. So West takes 2, East takes 1 trick.

I am sorry if i skipped any detail. For sure I am open to reply any variant "if" anybody wishes to analyze too.

Sincerely
Hamdi

I would follow the multitude and bid 2S. Having misbid this far, i bid 3S now.
Yes, duck the first C. Nice hand.

Yes I think so too. This is a theme that seems to come up around once a year, if you play a lot.

Obviously you don't have to duck a club lead when spades are 3-3. I meant what is the right play single dummy. Imagine if spades were 4-2...

Anyway it's not clear since they can switch to hearts and you risk being tapped there too. But I still think its the right play, you can duck the first heart as well and hope two rounds of diamonds stand up for a crossruff. I think.

The opps could shift to a heart at trick 2 if spades are 42. If they are always defending correctly then the "best" line is a simple ace of clubs, club ruff, ten of spades, spade. You make now on 33 spades or 44 clubs and 42 spades.

No, it isn't. If you duck the first club they will switch to hearts. Then if you try to draw trumps they will force the long hand and you will usually need trumps 3-3.

The simple line of A, ruff, 10 is better. They will duck the first trump and take the second, then play more clubs. You make if spades are 3-3 or clubs 4-4.

Edit: I see that half the world spotted this at the same time as I did. Shouldn't you lot be in bed by now?

So you duck a club, and then you duck a heart, and then you crossruff, scoring two aces, two diamonds, three trumps in hand, and two club ruffs in dummy. How many tricks is that?

The duck of the club doesn't just concede a tempo; it also wastes one of the small clubs that you needed to for your crossruff.

The question of how to play the hand given that trumps are 3-3 isn't very interesting. If trumps are 3-3, almost any line will work.

What we are discussing is how to play the hand single dummy, given that at trick 1 we don't know how trumps are breaking.

That is very true. I am impressed with myself that simply by mentioning it I got several to agree before being corrected though!

He told me why I was dumb (that I needed my small club so I could ruff it) so he is the one I acknowledged. No satisfaction for you!
