The Human Perspective: Analyzing Positions with Maia 2
How predicting human candidate moves calibrated to your rating provides essential context alongside engine calculation.

Free Daily Practice
Every feature is available for free for up to two training waves per 24 hours.
Why Structure Matters in Puzzle Training
Standard puzzle trainers serve an unending stream of positions and update a visible rating after every attempt. Without a natural stopping point, rising fatigue or a single mistake often leads to rushed calculation, guessing, and chasing lost points.
In physical athletics, training is rarely pushed to exhaustion in a single stretch; instead, workload is divided into sets that alternate effort with recovery. ChessKinetics brings this structure to chess calculation, pacing difficulty and enforcing rest before frustration sets in.
How a Training Session Works
Full walkthrough →1. Wave Loading (3 → 2 → 1)
Each wave steps through up to six puzzles: three easier positions to build rhythm, two closer to the target rating, and one final challenge slightly above it.
2. The Buffer Zone
A mandatory two-minute break runs after completing a wave or making a mistake, serving optional easy puzzles while giving players a pause to clear their head.
3. Fatigue Cutoff & Progression
Mistakes cut a wave short so players do not grind through fatigue. Target difficulty updates only between waves, rising after solving all six and stepping down only if the first two are missed.
Built for Calm, Focused Calculation
Read about the methodology →Hidden Puzzle Ratings
Puzzle ratings remain hidden while solving and only appear afterward, keeping attention on the board rather than the number.
Progress Without Loss Chasing
The Weekly Personal Record tracks the highest-rated puzzle solved in the last seven days and never drops after a mistake.
Unbiased Puzzle Curation
Puzzles are filtered for rating stability and sampled at random rather than by popularity, avoiding a bias toward flashy sacrifices.
Dual Analysis: Engine & Human
Post-puzzle review pairs single-line Stockfish 18 evaluation with Maia 2 neural network predictions, showing what human players at that rating level actually consider.
