White v red, imps: LHO deals and opens:
(2♦) 3♦ (P) ?
2♦ was weak and you guess that 3♦ was majors (your possession of all the aces makes the alternative meaning of asking for a diamond stopper impossible)
Unable to think of any method of finding how many diamond losers we have, such that we can make anywhere from 10 to 13 tricks, you compromise with 6♥.
All pass, and partner announces, while laying down his hand, that he doesn't have much. You tell him: 'I do' as he shows K109xxx Q1087x x K.
The opening lead is the ♦K (K from AK at this level) and LHO switches to a smallish (but not smallest) club.
Plan the play. Don't assume trump are 2-2
This may be easier than I thought at the time: to replicate the conditions of contest, all posters should drink 3/4 bottle of a good red wine before analyzing the problem
