US Chess Player Higher Rating Search

This Chrome extension adds a "High Rating" column to the US Chess player search page, showing the highest rating (published or current) for each player.

US Chess generates a list of official ratings every third Wednesday of each month, and it becomes official on the first day of the following month. These official ratings are to be used in US Chess tournaments for pairing purposes unless otherwise specified. Some tournament organizers use variations of the rule by using the higher of a player's current/unofficial and official rating for pairing purposes if announced in advance. This Chrome extension makes it easier for organizers to gather this information.

What It Does

• Adds a clickable "Click to Load" cell in the "High Rating" column.
• Fetches and compares the published/official rating (from MSA) and current/unofficial rating (from tournament history) when clicked.
• Displays the higher rating or "N/A" if data is missing.
