My chess site now lets you play engines on simulated historic hardware, ranging from 1970 to present

Hi everyone,

Just wanted to share an update about my site CCRL Challenger.

It lets you play against open source engines from the CCRL and it currently has 539 engine opponents across 152 unique engines.

https://www.ccrlchallenger.com

I've recently added a mode where you can play against the engines on simulated historic hardware, for example, a PC from 1970 running a 1MHz CPU. It automatically throttles the engine's CPU use to match the hardware of the time, which makes the engines significantly easier to play against. There are modes for 1970, 1975, 1980, 1985, 1990, 1995, 2000, 2005, and modern.

I've been playing around with it and I find it a lot more fun to play against the hardware handicapped engines in many ways. They feel a lot more manageable to play against compared to the full power versions.

Let me know what you think if you check it out.

Thanks. :)

I do not understand how it is possible to run engines of today on simulated historic hardware of 1970 because I believe the hardware of 1970 has not enough memory even only for the exe file of the engines.
