Using Stockfish as a Training Partner, Not Just a Judge
Most players use engines wrong — as verdict-deliverers rather than teachers. Here's how to make Stockfish actually improve your chess.
Stockfish can tell you your move was a blunder in 0.03 seconds. That information is almost useless for improvement. What actually matters is developing your own understanding — and for that, you need to use the engine differently.
The Interrogation Method
When Stockfish shows a better move, don't just accept it. Try to understand it. Force yourself to explain in plain language why the engine's move is better than yours. If you can't explain it, look deeper — check what the move prevents, what tactical shots it enables, what long-term structural benefit it creates. The explanation is the learning.
Play the Engine at Reduced Strength
Most training software lets you set the engine at a specific Elo or depth. Set it 200–300 points above your rating and play games against it. You'll lose, but the games will be instructive. The engine at this level will exploit your specific weaknesses without being so powerful that the games become meaningless.
Use It for Opening Exploration, Not Opening Memorisation
Feed it positions from your repertoire and ask "what are the main plans for both sides?" Don't memorise moves — understand why the top engine choices are made. This deepens your positional understanding rather than just extending your preparation.
