East was void in ♣ so 4♥ makes. West should have bid them anyway with 3 cards support and a very average hand (AK♦ and QT♠ 5th, which is the reason so he told us after the deal not to continue the preempt as we didnt belong in ♠).
Anyway, -170 among a long list of -420s was 2nd best mark (a declarer somehow mysteriously managed to take only 9 tricks).
Both S and N have uneasy decisions, and being red with an occasional partner didn't help for sure...
N at 1st: opening 1st seat red with very minimal values and such a lousy suit?
S: Xing risking that partner bids ♦, bidding ♣ at the 4 level, red, with KJ tight in opener's preempt and so weak spots?
N again: reopening (with 3NT I guess?)
All comments welcome, thanks
