GUI designed for contract bridge applications

jacobian

A minimal computer contract bridge communication protocol and implementation.

The jacobian protocol

The protocol supports four players and a host program.

In EBNF, every message here ends with a newline. The number of brackets signifies the number of such messages being sent and the direction specifies whether the recipient is a player or the host.

Currently no support for:

• bidding
• different scoring/goals
• forming agreements
• disclosure

The jacobian host

The host is an implementation of the jacobian protocol.
