IMPs, Partner has shown 8+ with 2245 shape, and we have all keycards. (♦Ace+♣King)
Now I have basically 3 options:
Blast 7♣ and hope ♥K is not on the left
Ask a lot of questions and end up in 6♣ if partner doesn't hold ♥K
Ask specific questions and end up in 5♣ if partner has no major King.
What do you think its best?
