"I'm currently ~650" ++ Then your only concern should be blunder avoidance. Always check your intended move is no blunder before you play it. Hang no pieces, hang no pawns.
"on chess.com bullet and blitz" ++ Do not play bullet or blitz, play 15|10 rapid.
"I'd like to improve my game, but I'm not sure how to most efficiently allocate my time."
++ Play and analyse your lost games.
"tactics puzzles" ++ Four tactics puzzles are a good warm-up,
but in a real game nobody tells you there is a tactic or for which side.
"reading chess books" ++ Chess books are no novels, you do not read them, you study them.
"which seems most effective" ++ An endgame book is most effective.
"much more time reading than playing"
++ About 50% play and 50% analysis of lost games or of annotated grandmaster games.
"just playing constant bullet/blitz is best" ++ No way. 15|10 rapid is best for improvement.
Hi guys,
I'm currently ~650 on chess.com bullet and blitz, and ~1500 on chess.com online/e-chess. I'd like to improve my game, but I'm not sure how to most efficiently allocate my time. Right now I do a sort of random mix of bullet/blitz games, pondering my moves in online chess games, tactics puzzles, and reading chess books (I have a few that I've been switching between depending on which seems most effective https://routerlogin.uno/).
I know for other games I've played, experts had a clear recommendation for how to best spend your time (like for poker, many suggested spending much more time reading than playing as a beginner). I don't have as clear of an idea for chess. I enjoy doing all of the above activities fairly equally, and I have one hunch that says just playing constant bullet/blitz is best, but I'd love input from better and more experienced players.
I got this,...
