Scoring: IMP
I think it's standard to open 1NT by South's hand.
Well, it also seems North's 2♣ is reasonable with 4423 and 8 HCP.
Obviously South will bid 2 ♠
Okay now i will try to assume North's options:
A pass
B 3sp - I think then South will decide to 4♠ with a maximum.
Quite surprisingly 4♠ fails. 3NT succeeds.
Any ideas please?
Thanks.
