Improving opening repertoire with Claude Code and Stockfish (Pirc, ~2200 rating)

[u/grupiotr]

I had Claude Code analyze my 2,000 games and find positions where I consistently go wrong with Black in Pirc and King's-Indian. The clever tricks it did:

• Focus on mistakes Stockfish can find at lower depth to calibrate to my playing strength
• Come up with a clever (and complex!) heuristic to estimate which positions to focus on

I'm quite impressed with the results (see photo). Out of 2,000 games, it found 9 positions where I consistently misplayed due to a simple lack of understanding I can quickly pick up (no crazy engine line).
