    Faq
    Q - Why do not you use a book / tablebase common to all chess engines?
    A - The chess engines are the result of the commitment of programmers; rules have been created to enhance their work. I think it's right to try to use everything that the programmer has created and nothing more.

    Q - Why 15 ' for each game?
    A - A shorter time would not fit well to the online matches (there could be problems for data transmission and difficulties for visitors to follow the games). A time longer than would make the tournament too long.
