Features & Capabilities

The Chess.com Analysis Sandbox is a manual move-testing overlay that lets you visually calculate variations directly on your active board. It contains absolutely no chess engine, making it a fully legal visualization aid for exploring "what-if" scenarios without triggering anti-cheat systems.

Instead of trying to hold deep calculations entirely in your head, this extension creates a safe, interactive shadow board right on top of your current game.

Core Features: -Visual Calculation: Drag and drop pieces to manually play out variations and test different move sequences. -100% Engine-Free: Relies strictly on rule-based move legality. It provides no evaluations, no bar graphs, and no "best move" suggestions. -Tactical Highlighting: Visually indicates legal destination squares, pinned pieces, and potential fork opportunities during your manual analysis. -Instant Sync: Use the on-screen Reset button or press 'R' to instantly snap the board back to the actual, live game position. -Universal Compatibility: Works seamlessly across live games, puzzles, and analysis boards.

How to Use:

1.Click the "Toggle Sandbox" button or press Alt + Shift + C to activate the overlay. 2.The real board is safely hidden while you interact with the shadow pieces. 3.Drag and drop pieces to calculate lines. 4.Press R to reset the sandbox and return to the live game state.

Is Gyamerz Analysis Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Gyamerz Analysis requires very minimum permissions.

Risk impact analysis details

High Injects scripts into web pages, which may alter or extract site contents, resulting in a substantial risk.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Gyamerz Analysis is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
