Dann Corbit (left) and Les Fernandez (right) are the main contributor of the EBF project. When Dann saw the potential of the project he created a selection of his huge collection of analyzed positions and donated 111 million deep analyzed (20+ plies) positions in EPD format including best move, score and depth.
There are no typos in the above, Dann since decades analyzes positions with top-engines, about the contributed 111 million he said: You got the tip of the iceberg, but it should be the premium ice.
From his words I understood he must have more than half a billion analyzed positions, a life time work.
So a big thanks Dann and Les for making the top of your (life time) work available for public consumption.
A quick overview.
