We have worked on the website for 5 Years now since year 2014. It's been free all the time. However it have costed and is costing money to run a website not to mention the work behind it. That's why we decided to make a small payment to keep the website going and still work with it.

If you want access to all content on you are welcome as a member.

We wish you good luck (No luck in chess, it's hard work to learn) but enjoy while you're learning. Hope you win some good games.

Best Wishes
