bridge-dds

A double-dummy bridge solver and analysis tool. Given a deal in PBN format, it computes the maximum tricks each side can win in every strain, derives the par contract, and (with a play trace) provides optimal continuation from any point in the play. Available as a standalone CLI tool and as a self-contained Web application.

Build

Prerequisites: git, g++ (or clang++), Rust toolchain.
