UltraCorr2024: how to buy


UltraCorr2024 is priced at 60 Euro, which is much cheaper than ChessBase's (smaller) correspondence database.

UltraCorr2024 is only available as a downloadable ChessBase archive file which you can obtain from either of two pages linked below depending on which version of ChessBase you are using.

If you are thinking of buying soon, please note that between 29 June and 12 July we shall abroad at a seniors chess tournament. Payments received during this period will not be processed as promptly as usual and it could be a day or two before you receive the passwords.

Here is how to buy UltraCorr-2024 securely using PayPal.

Our database is being offered in both the long-standard CBH format and the new 2CBH format which only works in ChessBase17. You can download either or both versions; the price is the same. They have different passwords. If you use both versions that is OK; there is no extra charge.

After download, you will have a large encrypted archive file (CBZ or 2CBZ format) which can only be opened within ChessBase, using a password which will be emailed to you after we receive PayPal's payment notification.

If you do not own the full ChessBase program, you can still use the database with the Fritz program interface. In that case, you will first need to unlock the downloaded archive file, which you can do using a free Chessbase-reader utility.


There are two options for payment:

1. Use this Pay-Pal-Me link to send your payment directly via PayPal (but please also send us an email).

This is a completely secure system run by PayPal; everything is done on their server and ensures you their usual buyer protections. We do not collect personal or financial information other than the email address supplied to us by PayPal.

Make sure you send us the correct amount: 60 Euro if you did not buy in 2021/2022/2023, or the discount price we quoted you in the email if you received it.

2. Alternatively, email an expression of your interest.
We normally reply within 24 hours to any queries and will send you a PayPal request for payment.

Very Important: If your payment is made on your behalf by another person (for example, your wife), you MUST email me to claim your password, naming the person whose PayPal account has been used. Otherwise we will not be able to match your payment and send you the password.

Warning: If your PayPal account is not in credit, it must be linked to your credit card to ensure the payment goes through promptly. Your PayPal account should of course also be linked to your bank account. If it is only linked to a bank account, we do not get quick confirmation and there will be several days' delay before you receive the password.

If you do not have a PayPal account, it is easy to open one and link it to your credit card. Once that is done, you can make purchases even if there is no money on your PayPal account. PayPal will handle the interaction with the credit card company automatically.

(We are not providing a link to PayPal because there are different home pages depending on where you live, and PayPal is easy to find online.)
