The situations described here are extremely simple examples; Many cases of expanded offers include specific agreements related to very specific situations and subtle conclusions about the entire call sequence. A bidder system is a set of partnership agreements on the importance of bids. The partnership offering system usually consists of a basic system, modified and supplemented by specific conventions (optional adaptations integrated into the main system of managing specific auction situations) chosen between the partners before the match. The line between a known convention and part of a system is not always clear: some auction systems contain certain conventions by default. Tendering systems can be subdivided into primarily natural systems such as Acol and Standard American, and in particular into artificial systems such as Precision Club and Polish Club. Opening offers on a level come with points of 12-13 points or more that are not suitable for any of the previous offers. With Standard American with 5-card majors, opening hearts or spade usually promises a color of 5 cards. Partnerships that agree to play 5-card major open an accessory color with 4-card majors, then offer their main color at the next opportunity. This means that an opening offer of 1♣ or 1♦ is sometimes made with only 3 cards of this color. Damage is classified as compensatory or punitive.
Compensation is rewarded in an attempt to put the innocent party in a position that would have been occupied “but for” the breakup.  These damages are most often awarded in payments. Punitive damages are awarded to “punish or exegect a criminal who acted deliberately, maliciously or fraudulently.”  In the case of the award of criminal damages, which is the case only in extreme cases, they are generally awarded with a right to compensation. Tendering systems differ to varyingly from these fundamental ideas. Standard American, for example, is a collection of conventions designed to enhance the accuracy and effectiveness of these basic ideas, while Precision Club is a system that uses the opening offer of 1♣ for all or almost all strong hands (but that sets the threshold of “strong” a little lower than most other systems – usually 16 high card points) and may contain other artificial calls to deal with other situations (but it may also contain natural calls). Many experts today use a system called 2/1 to force the game (like two on a forced game), which adds among other things a certain complexity to the processing of a Notrump response as used in the American Standard. In the UK, Acol is the most common system; Its main features are a low notrump aperture with 12-14 high card points and several variations for 2-level apertures. Search for: “Bridge Agreement” in Oxford Reference “The first type above is a real breach of contract. The second two species are violations of the future performance of the contract and are technically classified as breaches of the waiver.
The defaulting party waives the contract before the date on which it is required to meet its obligations. Violation of the waiver is more often referred to as “injury to anticipation.” A waiver (usually referred to as an offence or anticipated offence) is a clear indication that the party does not occur when the benefit is due or a situation in which future non-performance is inevitable. An anticipated offence gives the innocent the opportunity to terminate the contract immediately and sue for damages or wait for the time of the benefit: if the party obliged to the benefit does not meet, if the contract requires it, the innocent can then terminate.   Any offence – warranty, condition or unconditional – justifies the right of the innocent party to recover the harm suffered by the offence of the failing party.
