I've made a website where you can play against 118 different chess engines in your browser

I'm guessing you were playing BBC. I noticed that it hangs its pieces and generally plays poorly. No idea how it got such a high rating.

i know but the amount of bots you can play against are MASSIVE (i can imagine the replies to this ;-;)

and most of them are actually pretty good!

great but can you please add promotions of other pieces to make it better

Promoting to pieces other than queens is also on the to-do list. Unfortunately the chessboard library I'm using doesn't support promotion natively so I'll have to hack something together to get it working.

Just added a few small updates:

• Moved from Pagekite to Cloudflare for the localhost tunnel, so the pages are a lot more responsive and reliable now.
• Shows logos/release date/programming language under engine info
• Shows release dates and allows you to sort by release date on the engine list page

Ok, Thanks

Hi everyone, just a quick update, there's now a "Playing Now" page where you can see the current games. :)

I'm also planning to have a script that goes through each engine and tries to download the first version of that engine, so for Raven 1.30 which is rated 2590, it'll download Raven 0.30 which is rated 1450 and add it as an opponent, and it'll do this for every engine. Hopefully this should add a lot more lower rated (and human-beatable) opponents to the list.

Hi everyone,

I've been working on this project for the past few weeks. It's a website that allows you to play against engines from the CCRL in your browser. I thought it'd be fun to be able to play against CCRL engines without having to download and run them, so I made this site.

There are 118 different open source engines, all taken from the CCRL. I tried to include as many engines as I possibly could, but I could only include engines with Windows releases and permissive licenses that passed testing, which left me with 118 engines.

You can give the engine 1ms to 5 seconds of move time and play the games completely in the browser.

Please try it out and let me know what you think.

Cool but since you know this. I wonder why xiphos engine cannot be used to analyze my game? I use shredder GUI. Is it due to xiphos limitation? Because xiphos is quite cool since it can defeat shredder.

And the last, suggestion, can you make us to choose what engine to use to analyze our game in your website? That would be great because I always analyze my game with multiple engines. Probably many out there do the same :D

I'm not sure why you can't use Xiphos to analyse in Shredder, are you getting any errors?

The site is just for playing against engines, not analysis, but I might create an analysis tool involving multiple engines in the future.

It had no errors, but any game seems perfect for xiphos (no blunder, mistake, inaccuracy, etc).

Might just be a problem with how Shredder interprets Xiphos's output. You could try it in another GUI to see if you get the same problem, then you'll know if it's a problem with Xiphos or Shredder.
