Although Years of Playing Chess Improves People's Expertise at Playing

Although years of playing chess improves people's expertise at playing the game, it does not improve their overall memory. What evidence do we have for this conclusion?

A) Expert chess players are no better than beginners are at memorizing the position of pieces on the board when they are arranged as they might be in the middle of a well-played game.
B) Expert chess players are no better than beginners are at recalling what happened during the chess match they played yesterday.
C) Expert chess players claim that they use logic rather than mental imagery to choose their moves.
D) Expert chess players are no better than beginners are at memorizing the position of pieces on a chess board if they are arranged randomly.
