Auction Bridge and International Bridge (IB): A Bridge Variant
Auction Bridge and International Bridge (IB) represents a significant stage in the evolution of bridge, stemming from bridge whist and preceding contract bridge. Unlike contract bridge, Auction Bridge & IB features distinct scoring systems for tricks, bonuses, and penalties. The concept of vulnerability is absent.
While trump selection shares similarities with contract bridge, the latter employs a more intricate process. Gameplay and rules largely mirror those of contract bridge.
The dealer initiates trump selection, committing to winning at least the odd trick in a chosen trump suit or no-trump. The winning bid is determined by point value (excluding doubles), not solely by the number of tricks. For instance, 3 Spades (27 points) surpasses 4 Clubs (24 points).
Trick scoring beyond six tricks is as follows:
- No-trump: 10 points
- Spades: 9 points
- Hearts: 8 points
- Diamonds: 7 points
- Clubs: 6 points
A game is achieved at 30 points.
