4♦ made 10 tricks when someone opened a rounded suit and ♦A was in dummy.

It'd be nice to have more agreement about 3♦ (I usually just give up on asking doubler for a stopper, which means east should bid 3♠), but I think the biggest error was west sitting for 4♦X (given that he started with 3♦).

Can't fix it, but EW are actually vulnerable.

Edit the post and Change v=0 to v=EW

Wow, I don't think West is at fault for passing the double of 4♦, partner should have denied a fit and shown a good hand with diamond cards!

I think East should bid 3♠. Either that, or have some more discussion about cuebids in double auctions.

someone, that would be East?

Can't see any case for a heart or a club lead, would a pointed suit lead have beaten the contract?

Thank you, I tried switching the 0 to some other numbers but didn't seem to do anything . Now fixed

West's 3♦ was an overbid - if it's opposite a normal takeout double with short diamonds, there are an awful lot of gappy suits to worry about. Anyway, with that shape it's very likely that you're opposite a balanced hand that was too strong for 2NT, so it's best to start quietly.

However, the problems started before that. East had a 2NT overcall, or possibly a pass. By doubling, East created a problem for himself on the next round, because although he'd claimed to be suitable for playing in any of three suits, he wasn't, in fact, suitable for playing in any of them. So East bid 3NT, and West thought he was opposite a balanced 19-count. After that, EW were in a forcing pass situation, so a disaster of one sort or another was inevitable.

I blame East, because it was his ill-considered double that caused the problem. If he'd overcalled 2NT, it would probably have gone

2♦ 2NT 3♦ dbl
pass 3♠ 4♦ pass
pass pass

60% West and 40% East.

I agree with everything gnasher said about East's first double, instead of 2NT or pass. I also prefer 3♠ at East's second turn instead of 3NT. But I still feel that West really contributed a lot to the problem by bidding 3♦ instead of 2♠ and then passing partner's double of 4♦. East's misdescription of his hand is small compared to West's.

I dislike 3♦ more than I dislike (the first) double. In fact, I might even double at the table.

I think East has too much to pass and possibly miss a game, although I would certainly understand pass opposite a passed hand. But even though 2NT is a nice descriptive bid, it prevents us from playing at the 2-level in a suit. It also partner from making the (obviously very rare) penalty pass. Also, if partner isn't jumping/cueing opposite a double, we probably aren't missing game. So, for me, double as East is fine, 3♦ is the crazy bid. East should just bid 3♠ over that.

3D is too much.

The hand was more or less as follows (ignore duplicated pips)

touching clubs or hearts solves troubles for declarer but passive defence gives him a losing chance

[mfa1010]

I wonder what 3♦ means. If it shows a strong hand, as it would for me, then west is not close to having it. East's bidding can be questioned but he didn't do anything silly, it seems (all depending on the meaning of 3♦).

[han]

Yup, agree with mfa and it seems obvious to me.

[whereagles]

Take out dbl = liveable, but it's preferable to show what you have, i.e. bid 2NT
3♦ = somewhat optimistic, but the double makes it attractive
3NT = what's wrong with 4♠? (Not that it makes lol.)
Dbl to 4♦ = why dbl when there are prospects for a vulnerable game? I don't get it.

All in all I would say the initial take out dbl is the bid that caused the most damage.
