IMP, robot tourney, best hand South.

 

I am undecided whether this is worth reporting, or even whether North bid poorly (or South for that matter).

 

I was rather surprised to find partner with 5-4 in the majors and at best a tenuous guard in Clubs. OK, West's double shows 4-4 in the majors, but that does not preclude our having a major suit trump fit (and knowing how to deal with the trump suit). I feel that a Spade partscore on this hand would be better than 1N. If North does not bid 1♠ on this hand, what does 1♠ show?

[georgi]

1♠ shows spades just in case there is no other bid.

 

Same with 1♥.

 

But 1NT is superior because somebody of them have already claimed to have 4+ cards.

 

4+4+ in majors is certain in West, so bidding 1♠ would be forcing or not?

 

Also what would South ( with minorish hand ) proceed over 1♠ with singleton spade.

 

If you don't have obvious game like in this case, why would provide more information to opponents to double more easily.

OK, if all agree that 1N is the long term winning bid by North, I shall accept that.
