Chess Openings Lab

Embed an opening board on your site

Coaches, clubs and bloggers can put any of our 954 opening lines on their own pages: the board plays the moves, with captions, and readers can step, scrub and flip it. It's free; please keep the small credit link.

Copy this code into your page's HTML:

<iframe src="https://www.chessopeningslab.com/embed/caro-kann-defense/advance-variation/" width="480" height="640" style="border:0;max-width:100%" loading="lazy" title="Caro-Kann Defense: Advance Variation"></iframe>

Any line, by URL

The embed address is the opening page's address with /embed/ in place of /openings/. For example, /openings/sicilian-defense/najdorf-variation/ becomes /embed/sicilian-defense/najdorf-variation/. The list above shows the most-played lines; every line works.
