Auction Bridge & IB
Auction Bridge and International Bridge (IB) is a variation of the classic Bridge card game, representing the third stage in its evolutionary development from Straight Bridge (also known as Bridge Whist). As a predecessor to Contract Bridge, Auction Bridge & IB evolved from earlier games like Whist and Bridge Whist, laying the foundation for modern bridge variations.
One of the most notable differences between Auction Bridge & IB and Contract Bridge lies in scoring. The trick scoring, bonus scoring, and penalty scoring systems are significantly distinct. In Auction Bridge & IB, there is no concept of vulnerability—unlike in Contract Bridge—making the gameplay dynamic somewhat different.
The rules for selecting trumps are nearly identical to those in Contract Bridge, although trump selection in Contract Bridge tends to be more intricate. The play mechanics and general laws of the game remain largely consistent with Contract Bridge.
In Auction Bridge & IB, the dealer initiates the bidding process and must declare a contract aiming to win at least the odd trick—either in a chosen trump suit or at No-trumps. Bidding escalates based on point value rather than the number of tricks, meaning a lower trick count with higher points can beat a higher trick count with fewer points. For example, 3 Spades (27 points) beats 4 Clubs (24 points).
Each trick beyond the initial six tricks in a game scores as follows:
- No Trumps: 10 points
- Spades: 9 points
- Hearts: 8 points
- Diamonds: 7 points
- Clubs: 6 points
Reaching a total of 30 points constitutes a completed game.
