IMPs scoring.
I'm slightly annoyed by this one because partner only needs ♠Qxx ♥xxxx ♦Axxx ♣xx to make a grand slam in spades, but we barely make 4 spades sometimes when he has ♠ - ♥ KJxxx ♦xxxx ♣Qxxx, where 6 clubs is a decent contract. But, if he has something like ♠xx ♥Kxxxx ♦Kxx ♣xx I want to stay out of slam.
If you pass, it goes 2♥ - P - 3♥.
