Really neat idea, but if there's any type of CAPTCHA that a computer could solve... wouldn't it be this?

I mean, they've been kicking our ass in Chess since Deep Blue.

Earlier quoted context omitted.

I don't see there any need for a change Black plays; checkmate in one! This is the most obvious form for chess players; universally used throughout many chess quiz books.

Uh, if it's a CAPTCHA intended to be usable by those who know chess as opposed to those who actually play chess then yes, they should probably ask for what they actually want instead of saying something that will lead the user to the right assumption. Of course if it's really "CHESS player CAPTCHA" then I could be way off...

It's on a chess website, so yes, it's for chess players.

Screen readers have already been mentioned. But also, how about people from cultures that don't play chess? How about people from cultures that do play chess that just haven't ever given time to the game? I learned to play chess when I was a kid, but never had anyone to play with. The internet wasn't any help, either, because when you're a kid it's just not that much fun to constantly have your ass handed to you in a…

Whoosh

Looks impressive, but I got to say this. I am horrible at chess and couldn't find the move to checkmate white. I would probably get frustrated with this and not even bother to finish the form.

Too much fun. Setup a simple 'chess puzzle' website that grabs a captcha every time someone wins, forward the result and you get to post.

I am fairly certain it would be quicker to program a computer that can brute force a checkmate in one than I can solve these things by hand. You have what, 11 pieces, they can move into 64 positions each (at most, much less in reality). That means a computer must brute force 64*11 = 704 attempts. In other words, no time at all to bruteforce this once you've read the grid. Reading the grid in itself is rather trivial…

Good point. Maybe this could be used as an anti-captcha then, to prove that you are a robot (although i can't think who would want that)

Anticaptcha is easy to implement: just ask for some straightforward heavy calculation and require quick response (less than a second).
