Rainer, it seems to me that if you have 3 aces plus a trump trick then the contract is already down. But in that case you'd still like to set it two tricks, and indeed, I was hoping for comments about how to signal to partner that you'd like a trump promotion.
Of course, that's why I assumed declarer having both major suit aces.
If partner has 3 aces, it should not matter whether we force the dummy with clubs or play for a trump promotion.
The contract looks always 2 down at least on any minor suit continuation.
3 aces also means we could have made a high level contract ourselves however.
As to signalling. Standard is certainly that a high card denies interest in the suit.
Playing suit preference on the lead is difficult, since you have to signal 3 things on the lead:
Higher suit, lower suit or continuation of the actual suit led. This is fine when it is known that leader has many small cards to choose from in the suit led. But here?
