I was loathe to pass out 5♣ as North although I would have liked to be a little stronger. We had a chance to do well as it goes for -500 on best defence.
Sadly we didn't find best defence. Partner led the ♦9 and that ended any chance of getting +500. Declarer can now make 5♣ except after ruffing my king out and establishing the queen, he forgot to throw another spade so we got it one down. Due to the poor four table turnout it had only been played twice by the time it came to us, and one of those two pairs was allowed to play in 4♥=.
