While I think both version of the text would work, I think it's worthwhile to go over some reasons why the suggestion could actually be less clear than the original. 1) The two most important pieces of information (player color and goal) became separated from each other; 2) The third piece of information (number of moves) went missing; 3) The player's color became hidden in the middle of the paragraph instead of the first word; 4) The player's goal disappeared to the end of the paragraph, instead of in the first sentence after player color; 5) The original has a clear and unambiguous goal for both new and regular users, while the alternative became very verbose, especially for returning users. 6) Usability is about the target audience, and the target audience is chess players, not software developers. 7) In contrast to how the founders want to position the brand, a very watered down, a newbie-friendly CAPTCHA could alienate experts from the site, and an expert-friendly CAPTCHA could alienate beginners. To the OP: Since you have an established chess community, you should be asking them if they have a strong opinion rather than blindly taking advice from Hacker News :)
