depends of the kind off chess you are playing. If it is 1 minute online chess,..then not playing it might actually improve your horizon. If you are talking about slow games like G90 or so, then I agree it seems odd. Although it might be that you just needed some time for the patterns to 'settle in'
Whatever it is, its a good think so enjoy it.
I haven't been playing chess for almost a month now, but i have been doing 3 chess problems a day in TT. In 20 day my TT rating went from 1182 to 1433...when i played a lot of chess the highest i got in TT was 1297, i don't understand how is that possible, less chess playing yet my TT rating went up 251 points. Any explanations or opinions?
