Thanks nuss. The author @Jsmirand is a member here. The article resonated with me because I had a Fidelity Chess Challenger back in the day. I think the one I had was a Chess Challenger 7.

This code would be interesting to compile on the NeXT. I'm curious how many moves per second a NeXTstation Turbo with fast RAM could do.

I programmed this on my NeXT cube about 7 years ago or so.  It ran about 500 moves per second on a 68030, and about 1500 moves per second on a 68040.  In full disclosure, it is a very naive program, not well optimized.  Was just a personal challenge to code a simple game of chess.  I ported the code to a 2015 era 'modern' Core i5 Laptop and that rose to about 1 million moves per second if I recall. 

It was a fun exercise.   Only one line of code needed modification from NeXT to a modern laptop, if I recall was the include statement at the top...
