HI! New to this forum. Anyway just wanted to ask people's opinion about chess and memory. I belive that having a good if not superb memory is a preliquisite into becoming a good chess player espeacially on blitz. Blunders rarely occur on people with good memory because they tend to remember where pieces are and they tend to remember well chess theories and ideas better. I belive that concentration and creative thinking are also very important, but most world champions are known to have amazing memory.The supreme example is Bobby Fischer, a person who they say remember all the chess games hee had played. Including blitz! So any guys here think memory is the #1 preliquisite of a master chess player? or are there any other else?
Opinions? Ideas?

Sorry for my bad English

Somewhere on this site there are articles posted on the topic.
"Blindfold Chess".
I also posted in Chessville - Chess Instruction, News, Book & Product Reviews, Chess Fiction, and Many Other Chess Resources a more complete article with online resources on memory, blindfold chess.
The post called as well Blindfold chess.
Furthermore the post in both sites has resources on how to play blind folded.
For players with a supreme memory:
Philidor (Learned how to play blindfold overnight).
Najdorf - Played multi blind fold games at the same time.
Alekhine - Alleged to have memorized all of his 50,000+ games.
Although some games in his games appear to be suspect.
Spassky and probably Fischer - memorized games from a German series called in English "The World History of Chess". (By volume). Each volume a different player. Each book, a diagram every 5 moves.
Other than those mentioned above, another post in Chessville and possibly in Chessforum on a similar nature:
Mathematicians and Chess. A listing from a US Navy website on great players who were mathematicians.
Bringing to mind, Em. Lasker, Keres, Zuckertort, Steinitz, Euwe for instance who were mathematicians.
With Robert J. Fischer's play in US Championships a complaint at the time,
(from the NY Times) and other publications, the other players went to work
from 9 - 5 while Fischer prepared for each game at home.
As for blunders there was a Reinfeld or Fine book which had a chapter on the subject. Great players and GMs do blunder and make mistakes.
No player no matter how great is immune from the fate of blunders.
Alekhine possibly said it best. Memorizing moves does not work. Knowing
why the moves are made does.
