Nobody here knows what it takes to become a grandmaster, but it's hard to believe that improving your tactics beyond where they are now will get you anywhere.
If we threw you in to the top pool at Wijk aan zee, how many of your games do you think would be decided by your tactics rating being "only" at 3200 instead of 4200? How many would be decided by an inferior lack of positional understanding and/or endgame technique?
At the FM level, you'll only improve by playing tougher opposition and learning from every game, and I don't think you're going to find that kind of opposition who are willing to play at a slow time control on this or any other site.
I got a tablet for my birthday to do chess.com tactics on it. I am doing 25 in the morning and 25 problems in the evening.
I have about 12 hours a day to devote freely to chess and it struck me that although highly unpractical and unlikely to do, it would be interesting to see what comes out of doing chess.com puzzles/tactics for 6 hours a day.
that has to change you as a human personally. what are your thoughts on that?
I came up with 6 hours because in the U.S. tournament rounds are 6 hours long so its like simulating real life scenarios at a tournament.
pretty unlikely to do but there are people that are so crazy to improve that they would consider it.
what are your thoughts?
