If you would read what comment was written by the asker of the question, your question might be answered. I don’t speak for others. I let them speak for themselves.
I am glad that you showed the interest to respond to my information. I just logged in to answers.yahoo.com In the Search box for Yahoo Answers I typed 3-4 hours per day, clicked on the Search legend, and I got the thread with question, comments, and the discussion of myself and others.
Thanks. I had gone and typed in chess - searched several pages worth of text and found nothing. I now see that this actually under Canada Yahoo Answers, which may have made my search more difficult.
The question was “hello im a competitive chess player rated 1020 and i want to eventualy become a grandmaster so what do you think 3-4 hours per day is it enough”
You might want to spend some time solving tactical puzzles. At least up to master level, 30 minutes a day would be enough, or more than enough, if you do it every day. Say you spend:
30 minutes tactical puzzles
30 minutes opening prep (according to a disciplined plan)
30 minutes endgames (according to a disciplined plan)
60 minutes online speed chess practice
30 minutes reviewing selected games you’ve played, finding weaknesses and analyzing things you are unsure about.
That’s 3 hours a day that I think could take a master strength player up further in strength. I don’t know what it takes to get to GM.
How can a 1020 become a GM? That’s like the guy who asked “I’m going to get my first violin and I’m an adult, do you think I can become a famous violinist?” The best answer is of course “no” and beyond that, speculating on “how” is a bit pointless.
