Chess.com cheat engine with advanced humanization
Chess.com Cheat Engine v10.0 — Advanced Humanization
A Stockfish-powered chess assistant for Chess.com with state-of-the-art anti-detection.
Unlike basic chess bots that play the #1 engine move every time (and get flagged instantly), this script uses strategic humanization to mimic how a strong human actually plays.
Key Features
Engine Analysis
Stockfish.js running locally in your browser — no external servers
MultiPV 4 — always evaluates the top 4 candidate moves, not just the best
Dynamic depth (12–20) — adjusts per move based on position complexity and game phase
Lichess opening book integration for natural opening play
Anti-Detection System
The core of this script. Instead of always playing the best move, it strategically picks from multiple engine candidates:
Target engine correlation ~70% — chess.com flags accounts over 80%. The script tracks your best-move percentage in real-time and dynamically adjusts
Game-phase awareness — different suboptimal rates for opening (15%), middlegame (30%), and endgame (20%)
Winning degradation — plays worse when winning big (humans get lazy with a +5 advantage)
Losing sharpness — plays better when behind (humans try harder when losing)
Centipawn loss caps — "mistakes" are always realistic (max 40cp in openings, 80cp in middlegame, 50cp in endgames)
Streak management — never plays 7+ perfect moves in a row; never plays 3+ suboptimal in a row
Rare blunders (2%) — only in complex positions when already winning, never in close games
Per-game personality variance — each game randomizes suboptimal rate (±15%), depth (±2), and timing (±25%) so no two games look the same
Realistic Timing
Context-aware delays: fast recaptures (150–600ms), long thinks on complex positions (2–5.5s), book moves (300–1200ms)
Occasional instant moves (8%) — simulates pre-moves
Occasional deep thinks (6%) — simulates reading a long line
Fatigue simulation — moves get slightly slower after move 25
Suboptimal moves include extra hesitation (simulates "almost seeing" the best move)
UI & Controls
Draggable control panel with eval display
Green arrow = best move, yellow arrow = chosen suboptimal move, red arrow = opponent's expected response
Adjustable sliders for engine correlation %, timing, and suboptimal rate
Hotkeys: A = toggle auto-play, X = stealth mode (hides panel)
Auto-queue for new games
How It Works
The script doesn't just randomly blunder. It uses Stockfish's MultiPV output to get the top 4 moves with their evaluations, then makes an intelligent decision:
Is this an opening book position? → Play the book move
Should we play suboptimal? → Based on game phase, eval, streaks, and correlation tracking
If suboptimal: Pick from candidates weighted by centipawn loss (prefers 2nd best over 4th best)
Calculate delay based on position complexity, move type, and fatigue
The result: you win games while maintaining a human-like analysis profile.
