North went into a tank after the 2♣ bid. 2♣ was explained natural as ORF and not promising a rebid( don't even ask). For example if East had rebid 2♠ West could have passed. Alternatively over 2♣ North bids 2♥ and East bids 3♦, South bids 3♥ and West 3♠,pass by North and 4♠ by East.
What's your lead? Just kidding, I feel this hand goes down on any lead.
PS: It seems that the 2♣ was the equivalent of a fit jump...
All EW scores were making 10 tricks whether they reached game or not...but still... go with the bidding as shown
