According to this page:
cp the score from the engine's point of view in centipawns.
but is it a score for the current (start) position of the game that I feed to engine, or it is a difference between start and final(when coputations completed and best line found) scores?
And the range in which this value varies is unclear to - how could it be as big as 6000 that I sometimes get for my positions? That would be a ton of figures:)
