Blast from the past, GNUChess4

Post by Mike Sherwin »

I saw that Jim Ablett has a GNUChess4 exe on his site compatible with xboard. I used to play against this engine back before 1990 iirc on an 80386 50 MHz machine. I thought it would be nice to play a quick game against it for old-time sake. I did not put much effort into the game. But it was a fun game. I kept getting an advantage and giving it back. In the endgame I did make a fatal mistake but managed to draw. I like this engine's playing style!
