If Botvinnik in Stalinist regime told about the relationship between philosophy and chess, then would he off course say that the pawns are the most important and underestimated pieces in chess and that the pawn structure is at the very heart of any chess game.
Yet, if there is any positive relationship between philosophy and chess, then I have to agree with Andy Clifton that there is no relationship, because he is much better in chess then I am.
Not surprised it wouldn't ring a bell for you.
