https://aichess.co.uk/Club-level adult improvers rated roughly 1000-1900 on Lichess or Chess.com who already have Stockfish a click away but don't know how to interrogate an engine, read its evaluations, or turn its output into a training plan.https://aichess.co.uk/blog/001-what-a-chess-engine-actually-does-when-you-press-analyse/https://aichess.co.uk/blog/001-what-a-chess-engine-actually-does-when-you-press-analyse/A search tree plus an evaluation function is a decision procedure, not an oracle; understanding that Stockfish is ranking variations rather than pronouncing truths is the precondition for every other skill in this site.https://aichess.co.uk/blog/002-your-first-engine-analysis-a-ten-minute-workflow-for-one-gam/https://aichess.co.uk/blog/002-your-first-engine-analysis-a-ten-minute-workflow-for-one-gam/Most improvers either skip analysis or spend an hour scrolling arrows; a fixed ten-minute pass with four defined steps beats both, and this post gives the exact sequence to repeat every week.https://aichess.co.uk/blog/003-install-stockfish-on-windows-mac-and-linux-without-the-termi/https://aichess.co.uk/blog/003-install-stockfish-on-windows-mac-and-linux-without-the-termi/The official downloads page is a wall of CPU acronyms that stops people at step one; this decodes which binary to pick for your machine and gets an engine loaded in a GUI in under fifteen minutes.https://aichess.co.uk/blog/004-plus-1-20-explained-reading-the-eval-bar-without-panicking/https://aichess.co.uk/blog/004-plus-1-20-explained-reading-the-eval-bar-without-panicking/The eval is a pawn-denominated forecast of a perfect game, not a probability that you will win this one; calibrating what each band means for a 1400 changes which positions you bother resigning or fighting.https://aichess.co.uk/blog/005-inaccuracy-mistake-blunder-what-the-labels-actually-measure/https://aichess.co.uk/blog/005-inaccuracy-mistake-blunder-what-the-labels-actually-measure/These are arbitrary centipawn thresholds applied by the website, not chess judgements; knowing the cut-offs reveals why one-move oversights and slow strategic drift get scored identically and why that misleads you.https://aichess.co.uk/blog/006-stop-reading-the-engine-line-first-guess-then-check-analysis/https://aichess.co.uk/blog/006-stop-reading-the-engine-line-first-guess-then-check-analysis/Turning the engine on before you commit to your own answer converts active recall into passive reading; writing down your candidate move first is the single habit that makes analysis produce learning.https://aichess.co.uk/blog/007-depth-is-not-truth-why-stockfish-changes-its-mind-at-depth-3/https://aichess.co.uk/blog/007-depth-is-not-truth-why-stockfish-changes-its-mind-at-depth-3/Reported depth is a heavily pruned average, not a guarantee that every line was searched that far; eval instability across depths is a signal about position sharpness that you should read deliberately.https://aichess.co.uk/blog/008-which-engine-should-a-club-player-actually-run/https://aichess.co.uk/blog/008-which-engine-should-a-club-player-actually-run/Engine choice at 1000-1900 barely matters for finding blunders and matters enormously for explanation quality; the right answer is a two-engine setup, not the strongest single binary.https://aichess.co.uk/blog/009-is-playing-bots-cheating-yourself-sparring-versus-real-games/https://aichess.co.uk/blog/009-is-playing-bots-cheating-yourself-sparring-versus-real-games/Bots remove the two things that actually make humans improve under pressure — rating risk and opponent psychology — which makes them excellent for drilling and useless as a substitute for rated play.https://aichess.co.uk/blog/010-can-an-llm-coach-your-chess-establishing-a-baseline/https://aichess.co.uk/blog/010-can-an-llm-coach-your-chess-establishing-a-baseline/Language models cannot calculate but can explain, plan and summarise; separating those two jobs and pairing the model with an engine is the only configuration that survives testing.https://aichess.co.uk/blog/011-lichess-analysis-board-versus-a-desktop-gui-when-the-browser/https://aichess.co.uk/blog/011-lichess-analysis-board-versus-a-desktop-gui-when-the-browser/The browser engine is throttled, single-line by default and forgetful; this identifies the four specific tasks where that genuinely costs you and where installing a desktop GUI is overkill.https://aichess.co.uk/blog/012-building-a-blunder-log-that-actually-changes-your-play/https://aichess.co.uk/blog/012-building-a-blunder-log-that-actually-changes-your-play/Recording positions without recording the reasoning that failed produces a puzzle collection, not a diagnosis; a three-column log capturing the move, the false belief and the missed cue is what makes patterns visible.https://aichess.co.uk/blog/013-maia-explained-the-engine-trained-to-play-like-you/https://aichess.co.uk/blog/013-maia-explained-the-engine-trained-to-play-like-you/Maia optimises for predicting human moves at a target rating rather than for winning, which makes it the only widely available engine whose mistakes are informative about your own.https://aichess.co.uk/blog/014-why-stockfish-s-best-move-is-often-useless-advice-to-you/https://aichess.co.uk/blog/014-why-stockfish-s-best-move-is-often-useless-advice-to-you/The top line frequently depends on a defensive resource fifteen plies deep that no club player would find; the second or third choice is usually the move you should actually study.https://aichess.co.uk/blog/015-choosing-a-sparring-time-control-why-rapid-beats-bullet-agai/https://aichess.co.uk/blog/015-choosing-a-sparring-time-control-why-rapid-beats-bullet-agai/Bots don't flag, tilt or premove, so fast time controls against them train nothing but mouse speed; 15+10 sparring is the format where bot practice transfers to human games.https://aichess.co.uk/blog/016-hash-threads-and-multi-pv-the-three-settings-that-matter/https://aichess.co.uk/blog/016-hash-threads-and-multi-pv-the-three-settings-that-matter/Everything else in the options dialog is noise for an improver;

three lines tell you how wrong and whether your move was a near-miss or a category error, which is the difference between a score and a lesson.https://aichess.co.uk/blog/018-tagging-your-losses-by-cause-not-by-opening/https://aichess.co.uk/blog/018-tagging-your-losses-by-cause-not-by-opening/Improvers blame openings because openings are easy to name; a six-category cause taxonomy applied across twenty games almost always reveals the real leak is calculation hygiene or time use.https://aichess.co.uk/blog/019-leela-versus-stockfish-two-different-kinds-of-wrong/https://aichess.co.uk/blog/019-leela-versus-stockfish-two-different-kinds-of-wrong/Policy-guided MCTS and alpha-beta search fail in opposite directions — Leela underrates forced tactics, Stockfish underrates long-term compensation — and knowing which is which tells you when to run both.https://aichess.co.uk/blog/020-prompting-an-llm-for-chess-what-works-and-what-hallucinates/https://aichess.co.uk/blog/020-prompting-an-llm-for-chess-what-works-and-what-hallucinates/Asking a model for moves produces confident illegal nonsense; asking it to explain an engine line you paste in produces usable coaching, and the prompt structure that enforces this is reproducible.https://aichess.co.uk/blog/021-the-twenty-game-audit-finding-your-pattern-not-your-worst-mo/https://aichess.co.uk/blog/021-the-twenty-game-audit-finding-your-pattern-not-your-worst-mo/One game is anecdote and the engine will always find something;
