Seeking feedback on my chess website

Hi y'all. A few years ago, I made an interactive and fast site that recommends a chess move. It's called http://chessSuggest.com. It uses the Garbo chess engine to make a recommendation. The cool thing about it is that it runs on the client even though it's a website which means that the strength of your computer can improve the accuracy of the website. 

I haven't opened the code in a few years but recently I've had some people e-mailing me and I've decided that I wouldn't mind redoing it. Obviously I can't compete with the advanced software that this site offers in terms of analysis but for a quick accurate move I think the site is pretty cool. I'm asking for suggestions and feedback. Thanks!

EDIT: Before anyone mentions this, there are ads on the website. It helps me cover the cost of hosting. I don't make any profit from the site.
