Hey that's neat. I wonder how well it plays.

Very, very, very, very badlyit's a challenge for a minimal engine less than 1K

[Gryzor]

Ha Still, it's quite a feat to fit the logic...

Of course there was this: https://en.wikipedia.org/wiki/1K_ZX_Chess

Sorry I'm no help with this, but it's nicely coded, which makes me think it's out of a book, not necessarily an Amstrad BASIC book, I'm thinking more Generic given the look of the game itself, with a little bit of Sound and Graphical Title added into the code.

Wish I'd seen this before I started coding my Chess game on Symbos. Despite being a lot of articles & videos on chess engines its mostly irrelevant to z80 systems, and the code there is for Z80 is quite dense.

Someone else had a go at writing a chess game for the ZX Spectrum in less than 1K:

I looked at the code a few times but I couldn't make any sense of it - which is not surprising with highly optimised code.

Would people be interested in a breakdown of the code for my Chess game. Admittedly its written in Quigs for Symbos, so its Basic, but not CPC Basic... but obviously is a new game that runs on the CPC.

[Gryzor]

Yes please. I find the topic very interesting.

Here it is, so you can test it yourself.
I just found the game in my collection.
Have no idea where I got it from.

[Gryzor]

Thanks

Just tried a game - but the constant screen redrawing is so distracting...

[Johnny Olsen]

You have to time it, close and open your eyes.
Result no distracting. 

[Gryzor]

Not at all. My mind works like a ZX80 anyhow, it only processes stuff with the eyes closed
