A fair number of juniors have told me that they find that their game is not as strong as it was when they were younger. The remedy has always been to go back to technical. I dont think that answers the question. With more knowledge, the game should be stronger. I think something else is happening. I think somehow the fighting spirit has been eroded. It is very important to check the mind to see where the blockages are.
The fact is we do not have a healthy culture yet. It is very much still work in progress. Achievements are not fully recognised and ideas and independent thought are not encouraged.
When a player meets another over the board an important arsenal besides technical is self esteem and confidence in their own thinking.
