Pretty cool!

I like the interface, nice "drag routine" to show the piece in transit.

I played a quick mess around game:

1. b3 e5
2. Bb2 Nc6
3. e3 d5
4. Bb5 Qg5 (it's surprising how many programs go for this move with no book)

5. Nf3 Qxg2
6. Rg1 Qh3
7. Bxe5 Bg4
8. Rg3 Bxf3
9. Qxf3 Qxh2
10. Rxg7 Bxg7
11. Bxh2 Bxa1
12. Qxd5 Ne7
13. Bxc6+ bxc6
14. Qa5 a6
15. Qxc7 Bf6
16. Bd6 Rg8
17. Bxe7 Be5
18. Qxe5 Rg1+
19. Ke2 Kd7
20. Qd6+ Ke8
21. Bf6 Re1+
22. Kxe1 Rc8
23. Qe7#

Before I was able to see the reply, IE8 took it upon itself to tell me that a script on the page was causing it to respond slowly:

"Stop running this script a Script on this page is causing your browser to run slowly. If it continues to run, your computer might become unresponsive -I choose "no" to the end script prompt. This popped up after each white move WFT! Is Microsoft jealous because they did not write the program?!

IE has a timer that kicks in after about 2 seconds that warns about javascript "stealing" the cpu .

I probably don't check if I should finish searching frequently enough on IE. Still 15k NPS is very impressive for IE, mine runs at about 10k.

Nice game, congrats . Yeah, the javascript libraries out there are pretty cool, it's actually pretty easy to put something like the piece dragging together nowadays.

How hard would it be to convert the gui stuff for a game like checkers?

One thing I would like to do is have a web-based version of my checkers program play people online, like yours is doing. Rather than implement the a.i. all in Javascript, I'd prefer it if there was a way to communicate to an outside C-application.

Never really looked into it though.

It would be pretty easy to do a checkers GUI, you'd just need to do a move validator in javascript. Hooking it up to an outside C-application is quite a bit trickier, you have to host the application in a web service, or your web server, and have the javascript talk to that.

That Google Chrome browser must be the thinnest client with the greatest pass-through to the CPU!

Must be the Nehalem. I didn't think Safari was so fast .

That's pretty impressive. What does Chrome get on your hardware, I want to see if it's just the hardware or Safari has super powers.

Safari is very fast. I may compare with Chrome later, but I can tell you that Safari 4.0.4 (64 bit) running under OS 10.6.2 on my 2GHz Core 2 Duo MacBook was getting 150000 NPS. I can do a precise test later, when I have access to that machine.
