The chess grandmaster!

When I recently got my Commodore CHESSmate, I was curious to see how the CHESSmate, which in essence is nothing more than a modified KIM-1 with a 6504 CPU in which the whole chessprogram was stored in 4KB of ROM, would hold up against a modern day opponent.

For this, I loaded up the chess program on chess.com and placed the settings to “Hard”.  I thought that the CHESSmate would be no match for this modern opponent as even in the 70s people were quite amazed that a complex chess algorithm could even be stored in such a limited amount of memory.  An old press article from a German chess magazine even stated that the CHESSmate would be no match for an intermediate chess player.

Nevertheless, I wanted to see it for myself, so off I went inserting all the moves the chess.com opponent did into the CHESSmate and in turn making the suggested moves by the CHESSmate on the site.
To my surprise, the match was well balanced with some interesting and tactical moves being made by both systems.  It was then fun to see that after about 40 minutes of play, the chess.com opponent offered a draw!

So, even the hardest chess.com computer opponent was not able to beat this oldie from the 70s.  Peter Jennings, the developer of the algorithm for the CHESSmate (called Microchess and first available on the KIM-1 in 1977) really did some magic here!

In the next few weeks, I’ll be putting the CHESSmate into the arena against some other chess opponents and see how well it does against those.

 
Here we go for a game of chess!


Looks like the game is well balanced
