The Swedish system regulation rules

[Kungsgeten]

An Unassuming Club (AUC) gets less dots than Standard American, if playing weak twos and strong 2NT:

 

1C = Clubs and a major, strong with clubs, 15+ bal or any 19+ (natural or strong, 1 dot)

 

The rest of the opening bids are natural.

No Steve, any 15+ opening gets zero dots

By the way, how many dots do I get for playing 1NT as any weak one-suiter?

 

I forgot to write about this in my initial post. An artificial 1NT call, which isn't covered by the rules about suit pointers etc which takes precedence, gets 2 dots unless weak. If also weak it gets 3 dots. A bid counts as weak if it can contain less than 8 hcp. So 1NT 6-9 with 6+ cards in any suit gets 3 dots. 1NT 8-11 with 6+ cards in any suit gets 2 dots.

 

What about defence against strong or otherwise strange passes?

 

An artificial pass is considered as an opening bid. This means that if the opponents open with an artificial pass you may play whatever you want after such a call. A pass is considered artificial if it may contain more than 13 hcp or if it doesn't contain all weak hands (less than 8 hcp) with 4333 distribution. Examples:

 

Pass = 0-7 hcp or 17+ is artificial

Pass = 0-13 hcp is natural

Pass = 0-14 hcp is artificial

Pass = 0-5 hcp or 10-13 hcp is natural

Pass = 0-11 hcp, but not 4333 and 7 hcp (lets say you play mini-NT showing 7-10 hcp), is artificial

On the other hand, 2♥ defined as a preempt with four spades and a canape-suit which may or may not be hearts is somewhat difficult to defend but gets only one dot. Then again, EBU and WBF don't have issues with it either.

The EBU does -- it's not allowed at level 4. (You could play it as any combination of meanings which show five spades, with or without strong alternatives, or any combination of 5-4 hands which don't include hearts, again WOWSA.)
