Some of the features we are most proud of we are unable to offer without your support.
For £2 per month, you can help us pay for servers while unlocking all premium perks.
Why become a supporter:
The feature we most require your help to support is our server, which can search through 60GB of chess state data and return the most relevant information to you. We use this to let you explore openings in much greater depth by clicking the more button.
Supporter features such as the More button work on all datasets. The table below shows the approximate threshold of how many games are required in a state for us to show it.
Dataset | Free threshold | Supporter threshold |
---|---|---|
Lichess (Each filter) |
~200,000 ~2,700 states |
~800 ~780,000 states |
Kingbase | ~600 ~4,300 states |
~10 ~750,000 states |
ChessEngine | ~300 ~4,200 states |
~5 ~690,000 states |
The limit of how low we can take the supporter threshold depends on our server. The lower the threshold, the larger the data, the higher the cost.
This is where we depend on you to help support ChessRoots, become a supporter for £2 a month and get access to all features.
