Getting Started with CoreSquares
By Corey Zapin
Create Your Account
Head to coresquares.com and click Register. You will need an email address and a password. After registering, check your inbox for a verification email and click the link to confirm your account.
Once verified, you can log in and access your dashboard. The first thing you will see is the player search bar, which is the core of everything CoreSquares does.
Link Your Chess Platforms
Go to Settings and you will see options to link your Chess.com username, Lichess username, USCF ID, and FIDE ID. Linking these accounts tells CoreSquares which profiles belong to you, and it unlocks features like your personal game library and unified statistics.
For Chess.com, enter your username and CoreSquares will verify it through the Chess.com API. For Lichess, you can link via OAuth for a seamless connection. USCF and FIDE IDs are entered manually.
You do not need to link all platforms. Even linking one gives you access to game imports and analytics for that platform.
Search for Any Player
The search bar on the home page accepts names, FIDE IDs, USCF IDs, Chess.com usernames, or Lichess usernames. Type in a name and CoreSquares will find matching players across all connected platforms.
Player profiles show everything in one place: FIDE rating, USCF rating, Chess.com ratings, Lichess ratings, recent games, and analytics. If the player has games on multiple platforms, CoreSquares combines them into a single view.
Explore the Players Directory
Visit the Players page to browse top FIDE-rated players. This is a great way to explore the platform and see what detailed profiles look like. Click on any player to see their full profile with ratings, games, and analytics.
Import Your Games
Once you have linked your Chess.com or Lichess account, go to the Games section from the sidebar. CoreSquares will automatically sync your games from both platforms. You can filter by time control (bullet, blitz, rapid, classical) and by platform.
Each game links to a full board viewer with move-by-move replay, Stockfish analysis, and an evaluation graph. You can favorite games and add personal notes to any game for future reference.
