Yes, but in chess the player is the whole team - not an eleventh part of the team. You don't have a Ron "Chopper" Harris lurking around at the back to make up for a Peter Osgood up front (younger readers may not get this).
Sure, but you wont see the coach putting in Harris (or Vince Jones for the people a little younger

) as the forward guy who is expected to go past his opponent. Likewise in chess: How well would Tal have done if he had grown up on a forced diet of the queenless repertoire of Mednis?
As an example look at Alekhine. He knew he was weaker at "technical" positions than Capa, but he also knew he couldnt avoid them in the match. Therefore he worked hard on it, precisely because it was not only a weakness, but because it was a weakness that could be exploited by Capa. On the other hand Botters did the opposite in his 2nd match against Tal. Iso of working like a madman on Taltics, he looked for ways to avoid them. In the first match it was a weakness that Tal could exploit, but in the 2nd Botters avoided the weakness.
That is all not to say that you shouldnt work on all your weak points (basically areas that can be improved, in my case all areas

), but that it is best to focus on the weaknesses that are being exploited by nasty opponents.
