Stockfish on key positions
Scores at fullmove 13, 40, endgame entry (Lichess-style rule), and the final position.
Phase Elo
FIDE-style numbers for opening, middlegame, and endgame, from engine play and opponent strength.

Centipawns from your side, deltas (Δ) between sample points, phase colours vs opponent (±12).
Weekly charts
Calendar-week trends for opening, middlegame, and endgame in your selected range.
Openings & endgames
Openings page with global opening Elo and per-ECO line estimates; endgames grouped by material and theme.

Your history, with context
Games table
Your real chess level, measured with advanced analysis and data you can actually understand.

Opening, middlegame, endgame
Elo by phase and trend
Analyse your games like a pro and spot which part of your game is letting you down.

Per ECO line
Stats by opening
A table with ECO, variation name, wins, draws, losses, percentages, estimated Elo per line, and game counts. Expand a row to see sample games with opponent, result, and a link to each game.

Comparable endgame types
Endgames with data and games
You get a breakdown by material (white vs black pieces), results, percentages, and estimated Elo. Use “Games” to open real examples and see which endgames you play best—and where extra work will help most.

From engine to numbers you can compare
Engines quantify decisions in centipawns. Nexa chess organises that signal by phase, opponent strength, and time — so you train with evidence.
