Acasa -> Precision Club

[See also the Romanian version]

In these two tables I present the Precision Club bidding system; I've learned it around 1990, during high-school and since it remained my favourite system. Openings and responses are in the first table and in the second there are further bidding steps for some usual opening/responses pairs. Also available is a printable version with only the tables and nothing else.
