<a>: Evaluation of the position according to dbcn and expressed in centipawns (cp), from the perspective of the side to move.
<b>: Value in centipawns of the final move of the opening line, relative to the best available move, according to dbcn.
<c>: Popularity of the position in occurences per million games (expressed as 1/M) in the database underlying these pages.
