Came here to say these same things exactly. Best write up I know on this subject: https://use-the-index-luke.com/sql/partial-results/fetch-nex...

It's worth noting the streaming markdown renderer I wrote just for this tool: https://github.com/day50-dev/Streamdown

More background: https://github.com/simonw/llm/issues/12

(Also check out https://github.com/day50-dev/llmehelp which features a tmux tool I built on top of Simon's llm. I use it every day. Really. It's become indispensable)

The problem with tactics training is that there is always a "best answer" because they have been picked to have a best answer.

What got me playing over 1700 (lichess rating grin) were two things:

1) deepening my mental checklist: 1) am i being attacked, 2) are there unprotected pieces, 3) am I about to be forked/pinned, 4) can I fork/pin my opponent ... and increase how far down you can BFS this without getting a headache. And avoiding endgames because those are just logical grinds.

2) playing with an analysis engine like stockfish.

For me, memorizing defenses was not feasible because it is so broad, but I learned two openings (scotch and queens pawn) and at least know the defenses there because i know the openings. a little bit.

I'll keep at it, memorizing defenses, but I'm old and probably won't cram more into my brain.

EDIT: I used to go to a sunday-night chess meetup before COVID. 1700 on Lichess is nowhere near 1700 FIDE rating (of course, it was at a bar, so I'm usually a few pints in). I stopped going because I got tired of getting my ass kicked, there weren't enough mediocre players there.

I use:

    git init --bare $HOME/.myconf
    alias config='/usr/bin/git --git-dir=$HOME/.myconf/ --work-tree=$HOME'
    config config status.showUntrackedFiles no

where my ~/.myconf directory is a git bare repository. Then any file within the home folder can be versioned with normal commands like:

    config status
    config add .vimrc
    config commit -m "Add vimrc"
    config add .config/redshift.conf
    config commit -m "Add redshift config"
    config push

And so one…

No extra tooling, no symlinks, files are tracked on a version control system, you can use different branches for different computers, you can replicate you configuration easily on new installation.
