Not only is the delta chessbot bad (My low 1600s lichess-elo self can win handily every single time against any difficulty, white or black), but there's also a sequence of moves I found which deterministically causes the game to crash. I should probably record it next time I'm on a flight.

I'm 2100 rapid on lichess, 2050 blitz and bullet. I got destroyed every single time I played the easy mode version on Delta. It knew opening theory. It did not blunder a single time in the middle game. I never made it to an end game.

Sounds likely it had an opening book dataset. You just needed a weird opening

There's only one difficulty setting

If, as people suggest, the difficulty is time based, it would be easier on older planes.

I think you must be talking about something else, the Delta bot in discussion here has about 2500 ELO and basically crushes anyone who isn't a professional chess player.
