I'm curious why it's not deterministic. If I move E4, it seems to respond with one of three openings at random

The Kilobyte’s Gambit

#72I’m 700 or so at chess.com. It took me a few tries but I managed to beat it by exploiting its “appetite” for free pieces! nice !
Re: The Kilobyte’s Gambit
#73It took me 4 tries to beat it, and I have a rating of 1300 on lichess.org and 1100 on chess.com. In an effort to guestimate its strength a little more accurately, I had it play the first 4 levels of bots on lichess.org. It comfortably beat the level 3 (1400) bot and got crushed by the level 4 (1700) bot. Combined with beating me 3-1, I would estimate its lichess equivalent Elo rating to be somewhere in the 1400-1500…
Looks like it's rated around 1225:

#74I loved this footnote: "NB: if puzzled by a pawn move, please check for en passant before reporting a bug"
holy hell.

That doesn't answer the question. Yes, it's random, but why? Is it just to avoid repeating move sequences so you can't replay the same game multiple times?
Re: The Kilobyte’s Gambit
#77I beat it! (there has been several years since i played last time)
Re: The Kilobyte’s Gambit
#78Pretty cool game, nice job. It would be significantly better with just a little bit of opening knowledge, but obviously that isnt the point of this anyway. Im 1050 on chess.com and beat it first try, but the program sorta blundered the opening. I played the Queen's Gambit (very fitting)

I assume it's making a value-weighted move. To keep things interesting, you might choose from several moves that have similar EVs, esp. since the system only looks 4 moves deep, so there's uncertainty around how much better a given move actually is.
Re: The Kilobyte’s Gambit
#80My problem with this is that the colors make it hard to see the board. I get caught off by missing a long attack vector or a simple exchange. But this is overall an amazing accomplishment. I've played several good games with it so far.
I can't speak for OP, but I doubt this is intended to replace LiChess. It's a uniquely designed proof of concept and a great one. We can give it a creative licence.
Really the piece design is actively user hostile for any of us with less than perfect vision.
In particular the pawns and bishops are way too similar, especially black.
