I just play for fun but I found I play better under 20 open games.
10 games or less at the same time should be the ideal number for me. I tried more than 80 games and my brain crashed. To improve my game I am reading the book of Richard Palliser, with 1200 chess puzzles. I already did the first 100. (on Mar/31/2022)
