A variation of contract bridge, the Chicago format provides a shorter, more accessible game. It is typically completed in four deals, irrespective of whether a rubber has been won. The scoring method used in this variant retains many of the core principles of standard bridge scoring, including points for bidding and making contracts, overtricks, undertricks, and honors, but adjustments are made to accommodate the limited number of deals. For instance, if a partnership bids and makes a contract of 4 Hearts they score 120 point for completing the contract. Additional score will be granted if they earn over tricks.
The condensed nature of the game encourages more aggressive bidding and strategic play, as each hand carries a proportionally higher weight in the final outcome. This accelerated pace makes it particularly well-suited for casual play or situations where time is limited. Its accessibility has contributed to the game’s enduring popularity, fostering social interaction and providing a stimulating mental exercise. The game has also historically served as an introduction to more complex forms of contract bridge.
