Chess.com’s Computer Aggregated Precision Score EXPLAINED

Some of our members who play on chess.com may be unaware of CAPS. Or they may not be versed in its strengths and weaknesses. Simply put it is the chess.com feature for analyzing games. As an instructor I’ve come across this topic numerous times in discussions with my students. I strongly recommend that everyone playing on chess.com watch this video by Danny Rensch as he covers this topic thoroughly. It’s primary value is letting beginners/novices know if they’re in the ballpark and as such is immensely valuable. However as I’ve explained to my students CAPS is no substitute for rolling up your sleeves and doing your homework. As Danny points out in the video the default analysis is shallow. Also keep in mind that the server(s) which run CAPS are shared by all the users logged in to chess.com at any point in time. Thus CAPS is no substitute for a state of the art engine running on current dedicated hardware, i.e. a very strong PC at home. And that’s what I was referring to when I mentioned “doing your homework”. But for most of our members CAPS is very handy and valuable for getting a sense of how they were doing in a game. Just keep in mind the caveats pointed out by Danny and I. Have fun!
