1-year access to 7-man Lomonosov Tablebases
You can now access the service from any device via a web interface, without having to use the Aquarium or any other software.
Lomonosov Tablebases allow you to determine if any position with 7 or less pieces leads to a draw or can be won by either side - with 100% certainty.
If the game can be won, the path with the least number of moves until the end of this variation is shown, given that both players make the best moves possible. If the losing player makes a suboptimal move, he will lose sooner and the program will display the new optimal path.
