call me crazy but I bid 4nt. My p could not possibly pass and therefore replied 5♠ thinking I would pass. After careful consideration I rose to 7 ♣ I ruffed the heart lead with Q ♣ in my hand played 2 rounds of ♣ to partners AK. ♣ split 2-2 . I returned to my J ♣ then played J ♦ The queen rose to cover it and the singleton K fell on my partner's A. with opps having only the 9 ♦ remaining I ran all ♦ then finished with the A ♠ in partner's hand
