I have the same question
New chess.com bots & thier opening repertoire
Actually you can just choose the opening then the bot like so : https://support.chess.com/article/684-how-can-i-play-the-computer-from-a-custom-position
What’s the fun/challenge in knowing what moves they’re going to make? Why even play the game?
Why even bother studying kicks, blocks, and punches if you know the master will just keep you doing the same? Why even bother practicing and sparring to learn a skill where speed or a well trained automatic responses can be the difference between a win and a loss?

I swear Antonio with the Black pieces has played something other than 1. e4 e5 against me far more than 10% of our games. Just going to check.
And yes, I just looked through my records, and sure enough, when Antonio has Black, and I play 1. e4, the bot responded with e5 32 times, and something else 11 times. So more like e5 75% and "other" 25% (it's played the Caro, French, Sicilian, etc). There was a period where I recall it seemed to play the French a lot. Maybe they tweak the bots over time, at least with regards to their opening books?
For the free access bots, they've swapped out Antonio-Bot and replaced it with Wendy-Bot a little while ago. Wendy-bot does not always play the Caro against 1e4, so they may have modified it when that change happened. My most recent 1.e4 game against Wendy-bot, for example, was met with the French Defence (shown below).

Because we are humans and not engines. You cannot always just play the same moves and get away with it against a hunan. You can maybe do that to a bot. But that is not how you play against a human. Also there are a lot of exceptions to certain moves and rules (principals).

Also chess is vast so it I'd practically impossible to do that. But for opening theory we do like those stuff.
Is there a resource anywhere of what openings these bots tend to play? Either provided by chess.cm or crowd sourced in the forums? I've found they tend to have their own repertoires, and if I want to play against a certain opening I'd like to be able to pinpoint which bot to play without trying them all in trial-and-error approach.
