I participated in a tournament on
chess.com and I have to play like 12 games, 3 days per move, although it's plenty of time, I can't concentrate, I noticed that when I play many games, I lose because I make mistakes.
The thing is when you have 12 games to be played, you often find yourself, not playing at all or playing all the games simultaneously, to just get over with it, and do something else other than playing chess.
So in an ideal situation, what is the best number of games to be played per day or week for average users?
A side question, is it good to play such tournaments? I mean when you have many games to be played, you'll loose concentration (at least I do) so isn't it better to play live tournaments (15 or 30 min for each player) isn't that a better way to concentrate on the moves?
