You can pre-register now to join the registration queue.  You will pay the entry fee associated with your date of pre-registration whenever you pay.

To guarantee your place you must pay in advance as detailed here and in your acknowledgement email.  If you cannot attend then if we can re-use your place you will get a full refund as soon as your place is taken.


The list of registered and pre-registered players is here.  The entry list is in two sections:

Registered players have paid in advance and are guaranteed a place.

Pre-registered players are in a queue by date of pre-registration.

As soon as you choose to pay you are moved to the registered players list.  Once the number of registered players reaches the tournament limit the pre-registered players list becomes a waiting  list.
