Pretty solid regimen! Very encouraging to see that you're spending more time looking at annotated games + tactics + endgames than dithering about with openings (a notoriously inefficient way to improve for somebody at your current strength level)
Only thing I find missing here is a feedback loop (requires a stronger human player, NOT an engine!!! - this could be a relatively stronger friend, coach, people on this forum etc.) to critique your game losses and point out things that are not obvious to you about your move selection/choices etc.)
There are a ton of debates in these forums about "self study" vs. "getting external help " but honestly, if you really want rapid gains, having somebody poke and prod at your recent games is incredibly beneficial. If the public forums seem hit-and-miss for good game critique, join up one of the many groups that really do a great job of offering constructive advice about your game.
I have about 2 and a half weeks until school starts again and I really want to get my hands dirty with chess while I can.
Currently I'm 1460 rated OTB, but I hope to get quite a bit higher as fast as I can. I have an opening repertoire pretty much set, but I have yet to go through a lot of games and really understand the openings, I basically just know the first 6-10 moves in all the openings I play. I know some basic end game stuff, but I need to work on that. So for the next 2.5 weeks I've been thinking of following this daily schedule:
3 hours going through annotated games and trying to understand the reasoning for the choices that are made. Feel I need to invest quite a bit of time here since there are a lot of variations to go through and I really want to have a better feel for how I should continue my openings into the middle and later the late game. I have quite a few books from the starting out series which should be good for this.
1 hour tactics trainer. I feel I am at least reasonable at this since my rating here on chess.com is over 1800 in TT which I believe shows that tactics are a relatively strong part of my game.
2 hours endgame study. Will be using Silman's book and trying to get through as much as I can.
1 hour playing 15|10 live chess here on chess.com. Don't really have any people I can meet up with who are at my level, so I think 15|10 chess will have to do. I feel like I don't learn as much from faster blitz so prefer that time control.
So that's 7 hours a day basically. I'm guessing I will watch chess videos and stuff aswell and probably play more some days, but that's what I will be aiming for at least.
Does this sound like a good plan? Is there something I'm forgetting?
p.s. hope this is the right section for something like this!
