Thinking Machine 6: Play chess against a transparent intelligence

[light_hue_1]

Would be more interesting if it actually played chess. I mated it, it captured my queen with its king, I captured its king with a pawn, and then it declared a draw.

People should polish a little more before releasing these things. Who knows what the visualization means if the rules are this broken.

I can confirm it does not quite follow the rules. In my game it castled to escape a check, which is forbidden.

[Declanomous]

That sounds a lot like playing any game with a young child. The difference is you can't correct a game-playing AI when it doesn't follow the rules.

So in a way it's a lot like playing a game with a young child after you've stopped caring about the rules.

I'd find it more enjoyable if I could remember what pieces the abstract shapes represent.

You can get a checkmate in 5 moves: http://imgur.com/E5XTouu

I'm pretty sure this is quite old. I remember the exact same graphics from something I played with at least 12 years ago (I think it might have actually been in like 2001 or 2002, but my memory is vague).

[ubernostrum]

Multiple people on /r/chess are saying it also castles its way out of check (which is, of course, also illegal).

[catnaroek]

This AI is very stupid. Here's our game, I played white:

> 1.e4 e5 2.Nf3 Nf6 3.Nxe5 Nxe4

It's well known that the correct move here is 3...d6.

> 4.Qe2 d5 5.d3 Bb4+

Black could still limit its material losses to just a pawn with 5...Qe7.

> 6.c3 Bd6 7.Nf3 0-0 8.dxe4 dxe4 9.Nd4 Nd7 10.Nd2 f5

Completely inexplicable.

> 11.Ne6 Qh4 12.g3 Qe7 13.Nxf8 Kxf8

My pieces are still a little stuck, but I'm a full rook up! To my surprise, black was very happy to exchange pieces. The main thing that delayed the final result was my own imprecision.

I think they wanted you to notice the design and the thinking lines. They didn't set out to invent the world's best chess player.

[psuter]

I feel like the AI is particularly intelligent in its use of lines to distract me. Fun visualization otherwise, even though it's a little hard to really understand what's going on. At least I can tell which moves are not considered.

[sheepleherd]

what would make it much better along those lines (are you listening designers?) would be if it drew its thinking lines on the board but under the pieces.

because I can't study the board while it's thinking (it obscures all the pieces) I can't quickly learn if its lines are interesting or not

That's cute. It's running in the browser as ordinary JavaScript, not on a remote server. Unfortunately, Firefox 46 crashed about 20 moves into a game.

[danvoell]

I love the idea. Not sure if it is the best visual. What does a strong line mean versus a thin line? Does it mean you are thinking real hard about that route? I know it would be much more effort but it would be interesting to read what it is thinking. Which piece is it trying to get in the short term. What is the long-term rational.

[TylerE]

What bugs me the most is that it doesn't use anything even resembling standard iconography for the pieces.

[clickok]

I really liked this. Understanding what the AI is doing is usually something that comes with experience and a bit of analysis, but a good visualization can act as a shortcut to intuition. And this one in particular was nicely designed.

I think I broke your program. Its my turn and I should be able to take the King but the game keeps on going: http://imgur.com/ZLbHaLK
