How to enter

Please enter preferably using the entry form. Once entered, you will see your name in the entries page. If you need to email, send to the Tournament Director Phil Beck <pbeck173 at yahoo dot co dot uk>. You will need to supply your name, club, country, and grade. We also need your entry category as listed in the Entry Fee section above.

It is important that you enter at a realistic grade. You should visit the BGA rating page (or the European Go Database) to see your rating if you have not played in a tournament for a while. There has been a recent upgrade of all ratings.If you use the entry form, your latest rating is shown, and your previous grade is highlighted in blue if it differs much from your rating. Feel free to modify your grade if appropriate.

For the purposes of pairing and ratings, Country is regarded as the country where your current Go activity is located. So if you are playing in the UK, but not a UK national, consider entering with your country as UK. One reason for this is that your results will appear in the BGA rating list otherwise not. Another reason is that McMahon pairing tries to increase diversity of opponents, so avoids pairing players from the same club/country.


A ticket will be printed for each player who has pre-registered. These will be laid out on a table near the entrance door of the venue.

When you arrive during the registration period, find your own ticket, check the details, sign it and then place it in the arrivals box on the table. If necessary you can correct details on the ticket. It is important that you register only your own ticket, as we need to know that the ticket holder is actually present. No money is collected at this stage.

When you have finished your game for round 1, please pay your fee at the payment desk. After that you can review your game, or get refreshments, or explore Cambridge!
If you are missing round 1, please take your ticket straight to the payment desk.

Players who have paid by the time the draw is started for the second round, will be in the draw for the remainder of the tournament, otherwise not.
