This recent article lends some important clarification to the so-called 10,000 hour rule. Of course some of us have been aware of the importance of talent for some time, especially after post mortem analysis with a young Vishwanathan Anand. I understood that I’d never be as quick sighted as him or other top players even with 100,000 hours.
Having said that my many years of chess teaching has convinced me that what most people are missing is practice time. Often it is the opportunity that’s the problem, especially for those with jobs and families. But most usually it’s a lack of willingness to put as much time in as possible and over an extended period.
People try to circumvent this truth with quick fix methods that just don’t work. But most people can make good progress over time if they put 7-10 hours a week in and focus on core skills.
