[9front] pr chess engine

[lyndsay]

according to http://doc.9gridchan.org/other.peoples.stuff a "pr" was at 
some point developing a chess engine for 9front. i do not recognize that 
name and i do not see such software or any equivalent in contrib, extra, 
games, or shithub and all the ants repositories appear dead so i can't 
check them. does anybody have an existing version of this in source form 
or know where i can contact this pr fellow?

This page is now very outdated, iirc dating from early 2018.  I've seen pr
on #cat-v, but I'm not aware of him publishing his chess engine.
umbraticus has done a bunch of work on several of them [1].  There might
be a port of GNU chess somewhere, but I don't condone self-harm.  There's
also mycroftiv's purplechess [2], you'll need to read his posts to
experience it to the fullest :)

Cheers,

there are some ports here:

Thanks to qwx for crafty (amd64 only, iirc) and ngplay.
/src/games/chess.c is a program I use mainly for viewing
pgn and keeping track of email correspondence games
but it can also interface to the engines so you can play
a game. There are some bugs I'll get around to fixing
one day...

A while ago we had a few games on grid thru a gamesfs
I hacked together. That was fun; I should get it working
again. Also considered a FICS interface.

One day I'll try an engine. If you haven't found it already:

Let us know if you make something!

i have a vague memory of playing a gnu chess port i found on sources, and definitely of playing a gnu go port i found on sources, but i seem to only still have the gnu go code:

http://plan9.stanleylieber.com/src/gnugo.tgz

i do remember that none of the network features worked.

A network ready Go would be really interesting to me. I have barely no 
person I can play with (in person).

But, having the software doesn't solve everything. We also need players!

I was thinking the same, but I've never coded anything beyond my uni's
practicals. I'd love to give it a go with some help though!
(Although my x201 recently died, so I'll need a new box first.)

>But, having the software doesn't solve everything. We also need players!
I'd be delighted to play with you! We can still use IGS through telnet,
iirc I was able to play a game from 9front.

We only need this complex stuff if our system also handles the rules, 
which is not necessary in my opinion, especially for a simple game like 
go. I think, especially for a game like go, where the goal is not 
necessarily winning. Also people tend to bend the rules to adjust the 
game to their own needs, especially if it's not about sports.

I'm a purely casual player who does no special training and doesn't visit 
competitions. It's about having fun and good time with friends.

Theoretically, we can play in a whiteboard-fs, but having a neat gui 
application would be much better.
