Answers.Text: I'm pretty sure there's more than engine strength involved, as there are multiple personalities with the *same* listed strength. In order to believe this answer I'd need something better sourced than "I think".

Comments.Text: Nakamura played his bot a couple months ago: https://www.youtube.com/watch?v=mZ5yqDtkQXI I'd say from his comment "And it's playing my friggin' opening!" on game 2 that the bot probably indeed has a bit of his "personality" but I can't say for sure to which extent it goes. The bot also tried to flag him in the endgame, which Nakamura does a lot. Not sure if they kept it as-is when chess.com moved to their new bots UI though.

  I came upon [chess.com](https://www.chess.com/) playing against computer mode.
  
  I found a resemblance of two professional chess players over there.  
  Do they really resemble their gameplay, though? Does the AI mimic their past plays?

  I have spent some time playing the lower-rated bots, and can confirm they tend to have different "personalities". I'm not a strong enough player to explain exactly how they are different. However I have observed that some are more aggressive, and tend to gravitate towards particular openings depending on the color.
