That is definitely true, it's not good enough to secure yourself against a persistent attacker but I do think it's a good captcha:
It's a topical captcha that the target audience of the site will recognize and most likely enjoy.
It's significantly different from any other captcha so that automated untargeted bots will not be able to beat it
It has a high enough entropy that untargeted bots that repeatedly attempt to guess the answer will fail
People without a chess background most likely have to think about the answer in a way that makes buying human workers a less attractive option (maybe)

Anyway, the same effect could be obtained by writing a "captcha" that simply asks: "Click on the queen", a fixed chess board picture. They are assuming no one targets them, so it's not so important how hard it is. (until someone targets them)
- C1D 14y agoI have to agree with most if not all of those points but for some people that don't know how to play chess it would be harder. I thinks is pretty innovative but I definitely wouldn't try to release it publicly as an attack could easily use a DOM parser to bypass it.
