You are playing Acol, but you might have a similar problem in other systems

---

We play inverted minors 9+ with 5 or 10+ with 4, may contain 4M.

Partner has no 4M and has one of the following hands:

3334/3343 5-9
(23)44 5-9
(233)5 5-9
Any hand with 6+ clubs 3-9, the shorter the diamonds, the less they can have
2245 5-8

He will not ever have 5 diamonds

Pass?

Hi,

I am assuming he denies a 4 card major, this means, they have a 9 card spade fit.

If you bid 2C, you are bound to find a fit with p, he should correct back to diamonds
with equal minor length, ..., with 4 clubs and 3 diamonds he may pass, but you will
ruff with the shortage. You may end up in a 43 on the 3 level, but it wont happen very
often.

So 2C, maybe we awoke the sleeping dogs. That is the real downside.

With kind regards
Marlowe

2♣, a fun quirk of bidding minor suits. Partner will pull with 3 diamonds and pass otherwise (note that pass therefore implies at least 5 clubs - at most 3 spades, 3 hearts, 2 diamonds). With at least 3=5 in the minors partner has the luxury to choose.
Note that the opponents have a 9(+)-card spade fit, so with our known 8(+)-card minor suit fit we should LAWfully compete to 3m (and they should then likely compete to 3♠). Direct jump bids are strong though, so we have to let the opponents in first.

I am used to open 1D with 44 in the minors, regardless of suit quality,
so I am a bit hesitant to claim p has to pull with 3 diamonds, or that pass
showes 5+ clubs.

So am I, but that hand would not rebid a second suit.

I bid 2♣, the auction proceeded (X)-3♣-(3♠) and now 2 meta agreements get in each others' way.

Once we've agreed a fit, doubles are for penalties

Where 3 suits have been bid, X doesn't show extra values but shows 4 cards in the unbid suit.

I probably wrongly doubled, partner bid 5♣.

He put down Jxx, xx, Qxx, KQxxx and with the aid of the diamond finesse this rolled. +100 for 3♠-2 would have been just above average, +300 would have also been all the matchpoints. 2 pairs sold out to 2♠=, it should only make 7 tricks, but that would have been really good for them anyway.

4 cards in the unbid suit should only apply when we can have a fit there.
