Not a huge player of chess. But this is chess with a difference.
In this version of chess you play as you would expect, but after you take your go the computer starts to calculate it’s move. Normally when this is happening you wait around, not with the Thinking Machine. Lines start to draw all over the board while the computer calculates 1000’s of possible moves and future plays. You keep playing until you loose, or at least that’s what I do.

Interesting concept and makes for interesting waiting time. The pieces are not the usual representations and this makes it a little more difficult (I lost my queen because of this). I could not tell you how good a player the computer is because I am crap. I am also not sure what the transparent circles are surrounding the board while you are thinking.

Still I think it is worth a look at the Thinking Machine 4 just because it does something that I have not seen before, even if you don’t play a whole game.
“Those traces become a key to the invisible lines of force in the game as well as a window into the spirit of a thinking machine.”
