Strong chess champions use other parts of their brain as normal club players. This was researched and established at the university in Konstanz, Germany.
They proved that chess masters mostly rely on their memory while normal amateur players use other parts of their brain that have the task of judging and analyzing new situations. Chess masters with higher Elo Rating used more often their memory banks than masters with lower rating.
The process to remember is faster compared to judging, analyzing and pondering. This explains why a master is much quicker coming up with a good move as he relies on his memory banks where he has stored thousands of chess ideas, chess variations and chess positions from his past games. Whereas the amateur player is always confronted with a new position which he has to analyze and judge again from scratch. This takes a lot of time.
This leads to the conclusion that people, who have a photographic memory should be able to store a lot more chess ideas than normal people. If this is so, only people with excellent memory can become chess champions because this natural advantage (for example: photographic memory) can not be overcome with training. They all do training but only some of them have the abilities to become great players.
