At the recent FIDE event in Milwaukee. I had a chat with Gopal Menon(AKA blitzmaniac), the undisputed "King of CTS". For the un-initiated CTS (Chess Tactics Server) is a site that allows users to hone their skill at solving chess tactics. There are currently ~24,000 problems and ~20,000 registered users.
Gopal at the FIDE event in Milwuakee where he tied for 3rd place
Gopal is currently ranked #25 in the USCF age 16 list with a rating of 2035. For the last 4 years he has gone up one rating class every year. At this rate he should be a master by 2009. In one tournament in 2005 he went from 1594 to 1737!
When did you start playing on CTS?
Around the US Open in 2006.
How many problems did it take you to get to 2000?
50,000 What is the most number of problems you did in one sitting?
On a scale of 1-10, How helpful is CTS in making one a better chess player?
7-8, but there is no substitute to playing stronger opponents.
When you see a problem, what percent of the time do you remember the answer, rather than calculate?
I remember the solution about 75% of the time since I have seen each problem 3-4 times, but most of the time I calculate it anyway (some problems have multiple answers).
