A chess board I made a while back. Maple, walnut and oak with 2 1/4” squares. Making the board is easy compared to getting the finish right. Start with the wood surface itself. Flatten to 400, clean, inspect, repeat as needed. Flatten to 600, clean, inspect, repeat as needed. Go to 1000, clean, inspect and repeat. Then, apply 6 coats of a building finish material sanding between coats. Here, I used a polyurethane varnish. Then, wait out the cure time for the poly. I waited seven days. Then, rub out the finish. Flatten by wet sanding to 400, 600, 1000, and 1500, clean, inspect, repeat as needed. Then, go to a coarse pumice with an oil lubricant, then a fine pumice in oil and then to rottenstone using oil as lubricant. Looks nice when it’s done, but for the time spent to get the shine, you could play a lot of chess on a board with a couple coats of wipe-on poly.
