You signal UDCA and play a trump contract, e.g. 4♠.
You lead ♣K and partner overtakes with ♣A and he returns ♦A.
Dummy (your LHO) has ♦KQJx and you have ♦82. What do you - playing UDCA - typicaly play. The ♦8 to discourage or ♦2 because the ♦8 would be interpreted as a singleton?...Or is this more a lavinthal situation?

[wclass___]

♦8 would hardly be interpreted as singleton as you preferred not to lead ♦

So pard probably wants to give you a ruff with having a safe trick.. probably trump ace. Play small...

Else it could be singleton, then use lav

Sounds like count to me but please post a layout, so we can consider the logic of the situation.
Partner must have a point when he cashes the ♦A in such a situation.

Sorry, It was more intended as a general question.
In fact we play upside down attitude and standard count..Not sure if that is really compatible.

[JLOL]

you give count.

Better post the entire hand (or at least North-West). It's rather strange that we are looking at a doubleton diamond when partner is laying down an Ace and dummy has ♦KQJx. Did partner bid the suit? Did declarer? What's the club situation? Is there a singleton in dummy? Is there a threatening heart suit in dummy where declarer's diamonds could get pitched? I hate to nitpick but these things matter and I hate to generalize.

If partner bid the suit he might think we have a void and if seeking a ruff. Better give count.

If declarer bid the suit, your entry should be obvious in clubs, but I if dummy had a stiff club, then the card should carry SP implications, although this seems like a concocted situation.

You asked for it :

Scoring: IMP

---

2C*-(2S)-3C-(3S)
All pass
 
2♣=weak with ♣'s and if only 5-card ♣ then a 4-card Major at the site.
3♣=I prefered to raise ♣ iso negtaive DBL, thought it preempted - the not too strong opps -more.
 
I did lead ♣K and partner took over with the ♣A and returned the ♦A.
I wondered what I should play in these situations when playing reserved attitude and standard count.

This hand is too bizarre. What's up with the A♦ shift? If RHO really AQJxx, --, T9xxxx, xx? This defense is necessary if pard is Kxx KJTx, A, ATxxx

Only reason why partner would overtake to play ♦A is when he has ♦A singleton and wants a ruff. Yes, he can overtake with ♣A stiff, but that doesn't mean he has to play ♦A... So what do you signal? Count, since attitude is already clear.
