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 during each week, hosted variously by lute57, RogerPfi and Maysie.

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 has just had a major facelift but that work is now complete. The Site's URL is in the process of changing to http://ocp.pigpen.org.uk but both will work for the time being.

Latest OCP News

OCP Forums (02-Feb-2017)
Please do have a look at the OCP Forums. These are where we chat about Bridge in general, Precision and especially about OCP.

There are areas to discuss the System, different aspects of it and developments to it, others to raise problem hands, and a brand new "Absolute Basics" area where newcomers to the system can get tips on learning the basics of OCP.

Come and join us!
Sub-Domain Changing... (20-Jan-2017)
The main work to overhaul the OCP website is now complete. All the code and content has now been modified as planned and you should not be able to access any of the old-style pages. The only part of the site that hasn't changed are the OCP Forums.

The next phase of this work is now in progress: I am in the process of changing the "bbo.pigpen.org.uk" sub-domain to "ocp.pigpen.org.uk". The ocp.pigpen.org.uk sub-domain has already been created alongside the original and can now be used, but they both now point at "pigpen.org.uk/ocp/" rather than "pigpen.org.uk/BBO/".

Both sub-domains will be left side-by-side for the time being, but I will eventually remove the bbo.pigpen.org.uk one entirely. Please change any shortcuts on your system in the meantime.
