How about a personalized chess set as an anniversary gift? You could get a custom-made board with your names or anniversary date engraved on it and include a set of high-quality chess pieces made from his favorite materials. You could also consider getting him a book on chess strategies or a membership to a chess club, where he can play and learn new tactics with other chess enthusiasts. Another idea is to plan a weekend getaway to a city known for its rich chess history, such as St. Louis or New York City, and visit local chess museums and play in tournaments together.
Or you can get him a star map with the date of your anniversary.
