North passes

East has a natural 1♠ bid with plans on rebidding ♠ s (little did he know!)

South has an unusual 2NT bid showing 5+5+ in the minors.

West bids 3♥ s

North can make things difficult with 5♣ 

East has great support in ♥ s, does not have wasted values in ♣ s and has a source of tricks in ♠  s, so 6♥ is likely to be right. Well done to those who found it.
