How does the Bridgetastic System Builder work?

Choose a base bidding system (SAYC, 2/1, Precision, or Custom), then answer a series of questions about your specific partnership agreements - NT range, major suit structure, weak vs. strong two-bids, slam methods, competitive defenses, and more. Brian, Bridgetastic's AI bridge coach, compiles your answers into a complete, readable system document you can download or share with your partner.

What bidding systems can I build with this tool?

The System Builder currently supports three source-checked base presets: Standard American Yellow Card (SAYC), 2/1 Game Force, and Precision Club, plus a Custom path for partnership-specific notes. Each preset fills in sensible defaults for common agreements, and you customize from there. You can adjust any section - from your 1NT range and responses to your competitive methods versus opponents' 1NT overcalls.

How is a system document different from a convention card?

A convention card is a compact one-page summary for opponents - covering just the key facts about your system. A system document is for you and your partner: it's more detailed, includes explanations of why you play certain agreements, and covers edge cases. Use the Convention Card Creator for your ACBL card and the System Builder for your full partnership notes.

What should new partnerships focus on when building a system?

Start with the high-frequency agreements: what your 1NT range is, whether you play 4 or 5-card majors, how you respond to 1NT (Stayman and Jacoby Transfers), and what your weak two-bids mean. Get those right before adding slam conventions or competitive defenses. A simple system played consistently beats a complex system played inconsistently - every time.
