Andragogy is the art and science of helping adults learn. The art and science in this field are somewhat different from that for teaching children. This has technical and learning-style implications for teaching adults to improve at chess or advising them how to self-teach and self-train at chess.
First, a quick note about how this post was written, It was written by spit-balling with Google AI. I will call it spit-balling rather than researching. Excerpts of Google AI answers will be repeated verbatim but not in quotes and also they will be amended by my comments which will not be flagged as such either. The results may be taken at face value as possibly reasonable advice to be tested in adult self-training in chess. This is certainly the way I will proceed empirically to further amend and test my self-training efforts. I first note below why this should suit (very motivated) adult learners.
Some traditional chess training relies heavily on the "immersion method"—forcing a player to consume tens of thousands of random puzzles. For a child with an incredibly high rate of synaptic pruning and neuroplasticity, the brain automatically organizes this chaos into patterns. But for an adult improver, whose brain requires deliberate structure, high-relevance repetition, and error-focused feedback to overwrite existing neural pathways, this random approach is deeply inefficient.
The Cognitive Science Behind It: Adults learn best through error-amplification. When an adult brain makes a mistake, it releases epinephrine and acetylcholine, which chemically flag that exact moment for neural restructuring. By immediately flooding the user with similar, compounded variations of that specific mistake, your adult system would capitalize on that hyper-focused neurological window to force pattern recognition. (The epinephrine and acetylcholine claims could certainly do with research checking which I have not done.
The inability to execute chess tactics stems from three sequential bottlenecks. In cognitive psychology and chess coaching, this progressive failure is a well-documented breakdown moving from (1) limited pattern recognition (instinct) to (2) limited visualization (mental simulation) to (3) limited calculation ability, (managing branching complexity).
When any of these three layers fails, your tactical ability collapses. Here is a breakdown of how these failures happen and one possible targeted, systematic training regimen to address each level or phase:
Phase 1: Inability to See One-Move Tactics Fast Enough.
• The Root Cause: A weak pattern vocabulary. If you cannot spot a one-move tactic instantly, your brain’s "System 1" (intuition) isn't recognizing the configuration of the pieces. You cannot calculate a deep combination if you are spending all your mental energy trying to notice that a knight fork is possible.
• The Training Fix: Volume Drilling. One approach is to take pools of say 100 very easy tactical puzzles at a time using platforms like the Lichess Puzzle Themes.
Solve these under some time pressure at a rate that suits you, preferably where your success rate is in the zone of 85% to 95%. Re-do the ones you fail the next day. Lichess does not easily support more re-doing of two failures in a row etc. But the sheer volume (at least x hours a week, you choose) should ensure recurrence of failed motifs in variant forms.
• The Goal: Build automated chunks in your long-term memory so your brain flags close threats and opportunities (1 to 2 or maybe 3 moves) almost instantly without active calculation.
Phase 2: Inability to Calculate One Line Deeply (2+ Moves)
• The Root Cause: Poor visualization and a failure to identify forcing moves. Players often suffer from "wishful thinking," imagining their own active moves but failing to accurately visualize the opponent’s best responses, causing the mental image of the board to blur.
• The Training Fix: Quality over Quantity & "CCTV" Checks
• The Routine: Switch to medium-difficulty puzzles (Mate-in-2 or 3, or win-of-material lines).
• The Method: Strictly do not move a piece until you have visualized the entire line to the end. Sit on your hands. Use the CCTV scan (Checks, Captures, Threats) for both you and your opponent. For every move you make in your head, force yourself to look for your opponent's most forcing reply (their checks and captures). Write down your intended variation on a piece of paper before executing it to keep yourself honest.
• The Bonus Drill: Pawn Endgames. Solve simple king-and-pawn endgame puzzles. Because there are no long-range pieces, they are perfect for cleanly extending your visualization depth (e.g., counting out pawn races 5 moves ahead) without your mental board blurring.
Do at least x hours a week, you choose. Note the "x" means each of these Phases should be 1/3 of your tactics training time of this type.
Phase 3: Inability to Calculate Branching Lines (The Tree of Analysis)
• The Root Cause: A lack of calculation structure. When a position has multiple viable moves, an untrained brain jumps back and forth chaotically between lines, gets fatigued, forgets what it already calculated, and blunders.
• The Training Fix: Candidate Moves & Kotov’s Tree
• The Routine: Use complex, tournament-style puzzles where the solution isn't a dead-obvious sacrifice etc.
• The Method: Apply a strict, systematic mental protocol:
-
Identify Candidate Moves First: Before calculating a single line, list 2 to 3 attractive starting moves. Do not dive down the rabbit hole of move A without acknowledging move B.
-
Calculate One Branch at a Time: Pick candidate move A. Calculate it down its main line until the position stabilizes. Evaluate it ("White is winning a pawn"). Now drop it completely.
-
Switch to the Next Branch: Move to candidate move B. Calculate it cleanly, evaluate it, and compare the final evaluations of both branches.
• The Goal: Eradicate chaotic looping. Treat calculation like a checklist, not a random maze.
(I will add further possibilities to do with this if this post gets any interest or positive comments.)
(Note: some sources suggest setting Phase 1 at 25 % of this tactics training, Phase 2 at 50% and Phase 3 at 25%.)
I have considerably more I can post on these Andragogy issues. I have looked into it at some depth but it does remain speculative and experimental on my part. I do not say what I have written so far is news to chess coaches working with adult improvers but this information takes some digging out if you do not have a chess coach and you are attempting to adult improve at chess by self-coaching and self-training. I will also note I am old, 72 years. This puts me near the extreme end of the spectrum of adult learners (from a low base) and not the good end. But this extremity throws into high relief my need for self-applied andragogy if not gerontagogy if there is such a thing.
I hope @Benedictine and @NDPatzer among others will find this interesting.
