I loved this footnote: "NB: if puzzled by a pawn move, please check for en passant before reporting a bug"

I added it out of desperation after around 100 people on reddit claimed the black pawns are "cheating".

Speaking of rules : I noticed the AI was able to castle even though one of the square in the path was attacked by one of my piece. I'm not a chess expert at all (this AI seems much better than me ^^) but I thought it shouldn't be possible.

I wouldn't be surprised if it doesn't cover that, I can imagine it'd be tricky to include without adding tens of bytes (10-20 bytes could be freed up by using slightly hackier function calls to/from the display, so perhaps Óscar will add more features/intelligence one day)

Was it a long castle? In that case, the squares the rook moves through don't block the move, it's only the squares the king moves through that block the castling move, so f8 and g8 for short castle and d8 and c8 for long castle.

Ah! It might have been that situation indeed, but I don't remember which square was attacked exactly. Good to know :)

Nice work! I'm about 1850 in Lichess blitz, and it played at the level of an earnest 12 year old, which is actually meant as a compliment. It got crazy with its kingside pawns in the opening (no book knowledge), lost material pretty steadily and was checkmated down a queen, bishop and two pawns by move 25. But it developed some pieces sensibly, made obvious recaptures and was not reckless about king safety. It avoide…

I just checkmated in seven moves. e4 h5 Bc4 e5 Qf3 Qe7 Nh3 g5 Nxg5 QxG5 Qxf7+ Kd8 Qxf8+mate

I can't distinguish the pieces well enough to play a good game. Anyone have this plugged into lichess?

Glad I'm not the only one. My vision isn't bad but the way the black pieces are shaded and shaped makes me have to put conscious effort into identifying them. (Not that I'd be able to beat this thing anyway)

In my experience having small webapps, it hardly helps. I literally added a huge modal popup on my feedback button specifically saying "DO NOT MESSAGE ME ABOUT X" before continuing and I still get dozens a week. Even on reddit, when you get a high ranked comment, you will often get the same reply over and over again, even though a similar response is already the highest ranked reply to yours. There are people who jus…

Reddit sadly went the way of mostly write-only microblogging a long time ago now. I'm not sure what the solution is between invite only subs or heavy and time consuming moderation, and random comments that are just people thinking out loud, as using any sort of karma metrics would be useless when you can get 20-30k off a no effort post in a popular sub, but I also doubt that reddit the company spends much time worryi…

> it's felt very true as audience size exploded

I think this is the key point. As with most issues on the internet, it's mostly an issue of scale. I assume these problematic users are actually only a very small fraction overall, but as the overall size grows, so does the number of people who belong at the very edge of the bell curve in terms of "normal" behavior.

With scale, any rare issue becomes common enough to be annoying.

"ply" :) The "How it works" link says it looks ahead 4 moves, that's probably 2 ply.

I was a bit lax using 'moves', it's 4 ply, so that's 2 full moves.

Oh, hey, you're the developer, right? Thanks for clarifying :)

Can you say what the lookahead is like? Is it a version of minimax?

Yup, my first try I made two major blunders due to confusing knights and bishops. Beat it easily on my second try. (When my allergies aren't acting up I'm 1600 on Gameknot.)
