OCP Super-Precision

OCP is a Super-Precision bidding system loosely based on descriptions of Super-Precision by Benito Garozzo & Giorgio Belladonna, and also by Eric Jannerstern. I say loosely, because over the years OCP has developed in many directions away from the Super-Precision of the 1970's and 1980's. OCP makes more extensive use of Asking Bids, Lebensohl and has advanced techniques for coping with interference in Asking Bid sequences.

The original system that I developed firstly with Bob Bradbury in the early 1980's, and later with Jason Hackett was a system primarily intended for use in Team events. Some of the Openings only gained Restricted or even Experimental licences at the hands of the English Bridge Union, but most of the system is equally applicable for use in Pairs events. In recent years, the system has developed even further, with more extensions and some new Asking Bids. Since 1992, however, I have played exclusive online via Bridgebase Online and the restrictions that the EBU or ACBL would place on us do not apply there.


BBO is where I play my Bridge these days. It's the world's best Bridge site and provides a wealth of facilities. The Intermediate/Advanced Club (IAC) on Bridgebase Online is a friendly and relaxed private Club for players who want to improve their Bridge.

A number of regular teaching classes are held in IAC and I (OliverC on BBO) run a regular 12-month Course on OCP Super-Precision in IAC, each Saturday at 9pm GMT/UTC. Regular practices are also held on Sundays (by Lute57) and Thursdays (by RogerPfi).

This Site

This site gives full details of the Super-Precision that I teach (OCP) for people attending those classes and any else interested. Details of the system can be found via menu at the top of the window. The site is extensive and there is also an message Forum where OCP devotees discuss the system and assist each other in their studies.

The site is currently undergoing a major re-write but should remain usable. Pages will gradually be switched to the new format (as this page) as I re-code them and re-write the content.

Website Disruption (28-Dec-2016)
I am embarking on a long-term project to re-write this site in order to make it more mobile and tablet-friendly and to update the underlying code, which is a number of years old now. This involves pretty much completely re-writing every page on the site to use a new CSS file, re-write the php code to update it to php5.5, take better advantage of what HTML5 has to offer, and to move the static content into the database.

There will occasionally be some disruption to the visible side of the site because some of the underlying database tables will have to be changed. I will try to keep that disruption temporary and a minimal as possible.

New 2D Responses (16-Dec-2016)
The website notes for the 2D Opening and Responses have now changed. Please have a look here for the details.

The (Word and PDF) for the Simple System have both been updated with these changes, and the Full Disclosure files (Simple vs ???) have also all been updated and should be re-downloaded if you want to use ones with the latest changes. To view the discussions that led to these changes, please have a look at the OCP Forums.
