Säffle Spade


In the game of contract bridge, Säffle Spade is a forcing pass-opening system developed by Einar Bergh and Pontus Svinhufvud; Säffle is a small city in Sweden where they once lived. There are at least three variants of the system: Super Säffle Spade, Small Säffle Spade, and Small Happy Säffle Spade.

Treatment

;Opening bids of Pass and 1
While the opening bid of Pass is forcing for one round, it does not promise a very strong hand. The basic idea is that all hands with 8 or more high card points and 4+ are opened with a Pass. If one has 8 or more HCP and no suit, but 4 or more, one opens 1.
The general rationale is that when you open very low, you want to hold and show the major suits, so opponents cannot easily pre-empt against you. Another advantage is that when you have 8 or more HCP you often tell partner immediately which major suit you do not have, and when he sees that your side cannot have any major-suit fit, if appropriate, he can quickly pre-empt with a minor-suit bid.
;Other opening bids in the system
Today, the system is illegal in most competitions, since a "Pass" opening now may not be used to indicate strength.
In the 1970s/1980s when it was invented and actively played, such regulations were rare.
