Klar.gg Chess

Klar Chess Bot reads the board state and interfaces with an internal engine rather than hooking into Chess.com's application memory. It's designed to work on both Chess.com and Lichess.org through a browser-compatible approach. The engine depth and maximum Elo are user-configurable through simple sliders, which lets you dial in exactly how strong the bot plays, low depth for modest improvement, higher depth for approaching engine-level play. The Auto Move feature fully automates your moves with configurable delays so each move appears to take a realistic amount of thinking time.

Chess.com's Fair Play analysis compares your move accuracy against Stockfish recommendations and flags statistical outliers, a player making engine-perfect moves across 40+ games is unmistakable. Safe depth settings depend on your current rating: at 1000-1200, depth 6-7 produces 1400-1600 ELO quality play that looks like a rapidly improving beginner. At 1400-1600, depth 8-10 produces 1800-2000 quality, a plausible jump for someone 'studying seriously'. Never jump from 1000 to GM-level accuracy in a month. The Klar Elo slider lets you set a ceiling directly, which is more reliable than trying to infer ELO from depth alone.

Klar's Auto Move feature includes a configurable base delay plus a max random delay, these two values create a range of thinking times for each move. A real human spends more time on complex tactical positions and less on obvious moves; the system simulates this variation. Chess.com's detection also monitors time-per-move consistency, a player who takes exactly the same amount of time on every single move regardless of position complexity is a statistical anomaly. The random delay component prevents this by introducing realistic variance. Set a base delay of 5-15 seconds with a random variation of 10-30 seconds for the most human-feeling profile.

The bot adapts to whatever time control you're playing. In bullet (1-2 minutes) the engine naturally plays faster since move processing time is minimal. The humanization delays should be set much shorter for bullet (1-3 second base, 2-5 second random max) compared to rapid games where longer delays are appropriate. For blitz (3-5 minutes), medium delays work. The engine quality at low depth is sufficient for all time controls since the depth limit is about result quality rather than calculation time. Bullet using the bot is inherently more detectable than rapid because move-time patterns are more compressed and anomalies stand out more clearly.

Chess.com's Fair Play team reviews flagged accounts by examining move accuracy statistics, time usage patterns, and performance consistency across dozens of games. Their review is statistical. They analyze the moves you played and compare against engine recommendations, not what's running on your screen. With proper depth limits and realistic move delays, your game statistics look identical to a legitimately improving player. The most common catch is players who use maximum depth without any humanization, near-zero centipawn loss across 40 moves is unmistakable even to a human reviewer without any automated tool. Klar's configurable depth and delay system is specifically designed to prevent this signature.

Klar Chess Bot is designed to work on both Chess.com and Lichess.org as stated in the product description. Lichess uses Irwin and Kenneth as its AI fairness analysis systems, which function similarly to Chess.com's Fair Play. They detect statistically unlikely move sequences by comparing your moves against engine recommendations. The same depth and delay humanization guidelines apply: use depth settings appropriate for your current Lichess rating, enable move delays calibrated for the time control, and avoid the engine-perfect move accuracy that flags both platforms' analysis systems. Lichess.org tournaments use the same rated game infrastructure and are subject to the same fairness analysis.

A Chess.com fair play freeze (distinct from a ban) typically means your recent games have been flagged for review and play is temporarily suspended while the analysis completes. Do not contact Chess.com support to dispute the freeze if you're actively using the bot, the move data submitted with your account is what's under review, and the freeze decision is data-driven rather than accusation-based. The most common outcome of a freeze with borderline statistics (appropriate depth, proper delays) is account reinstatement after review. A permanent close means the statistical evidence was conclusive. Prevention: reduce depth and increase move delays immediately if you notice your accuracy statistics trending toward 99%+. This is the signal your settings are too aggressive before a freeze occurs.
