My Chat Made a Chess Bot

[@FuryJack07]

6:58 I'm surprised they didn't add the simplest rule: if it's checkmate, +1000

[@gulgaffel]

But that would mean it would play mate over en passant

[@predwin1998]

Checkmate should be +95 or something. Can't risk it overruling en passant.

[@gulgaffel]

@@predwin1998 95 still risks mate being played over en passant. For example if something is mate whilst also taking a queen.

[@Marimo344]

I mean you could make en Passant worth 1000 points while checkmate is 500

[@AavyanTiwari]

Nah +infinity cuz then infinity+100=infinity so it'll not en passant mate

[@JustGreendude45-vu4hg]

I love that my suggestion decided the opening.

[@JustFootballEditz111]

What was yours again

[@JustGreendude45-vu4hg]

@@JustFootballEditz111 mine was the -2 for each of our knights and bishops on the starting rank. And +2 for each of the opponent’s knights and bishops on the starting rank.

[@onomenodafen-j2w]

Congrats

[@OTucanChannel]

I think Chatfish wouldn't take the free Rooks, because they were attacked by the Queen. And the rule specified, that only a lower value piece taking gets points, I think

[@GreenLemonGames]

That's definitely part of it, but the rook not being on the board would still make the score 5 points higher. I imagine it was a mix of the center code and the code that incentivizes forks, since capturing = no more fork

[@Woocha1]

​@@GreenLemonGames typically when chatfish can take a free rook it is the earlygame, so if he takes the rook he would still be forking a backrank piece and the pawn on the edge. I think chatfish would still gain a little points from the capture, but chatfish would prioritize other rules like sticking pieces into the center

[@BananaWasTaken]

@@GreenLemonGamesdo you think the rule at 2:52 (where having a piece attack more squares gives more points) also played a part?

[@OTucanChannel]

​@@GreenLemonGames True, I forgot about the center part

[@SusDoctor]

En passant is its favorite move. It only loses cause it didnt play en passant.

5:06 This rule doesn't exactly do nothing. It incentivises promoting to a bishop if you only have one (even if it's on the same colour square).

[@dark_luls]

21:26 Martin checks both kings 😂

[@Peopleofthepeople826]

5:09 it’s relevant for promoting a pawn into a bishop, but thats it

[@Noteturtle90]

Knowing chat, this'll be either very good or VERY bad...

[@Trimman45]

it only won that 1 game bc it played en passant, en passant will return

[@HuntingKingYT]

Make the rules: Every push of a pawn is +1 The further a knight/bishop/queen is from the enemy king is -0.125 per square (use Pythagorean theorem), same for pawns but that's from your king, for a rook it's like pieces but you count the shortest between horizontal and vertical Mate is +999, en passant (the only rule that isn't applied for the other side) is +9999 Pieces are counted normally, including hanging them If you can attack with a different type of piece (except queen vs bishop/rook or vice versa) then +2

[@DWayneLiscano-k9m]

For me it's: Each piece is counted normally If a piece is attacking, +value of piece thats being attacked If a piece is being protected, +value of piece thats protecting Check is +50 Mate is +75 En Passant is +100

[@wsurviver8376]

[@sorow9523]

I woul just make there safe zone, that is circle with 4 pizzas, so there could be new mechanic. Safe zone is just zone which is playable with other than soldiers.

[@Nf3IsTheBestOpening]

the first move makes up for everything

[@Quartz512_]

14:44 anyone know why chatfish didn't pick the fork? Like, there's extra points for a fork, and there's extra points for attacking pieces, surely the points for the two more squares it could go don't counter all of that

[@GreenLemonGames]

There is also an additional central square that it can move to, which likely makes up for the 1 point that the capture gives

[@GMArnavVerma]

Martin is ChatFish.1 Chatfish us Chatfish.2

[@asdfghyter]

it would be nice if the code showed how it came to its conclusion. in particular, it would be nice if it showed which rules contributed to the score difference between the selected move and the previous position

[@majbabno8729]

Could you open source the code? I think it would be fun to poke around in, see how adding or changing point values for rules would affect it

[@rubenlarochelle1881]

Me trying a simple algorithm as an exercise: +1000 for checkmate +60 for check -60 for opponent's check +2/+6/+6/+10/+20 for each pawn/knight/bishop/rook/queen you have -2/-6/-6/-10/-20 for each pawn/knight/bishop/rook/queen the opponent has +1 for each square your piece can reach (for each piece) -1 for each square an enemy piece can reach (for each piece) ... ... Ok I can't resist: +2000 for En Passant
