The tag computer-chess has at the moment 4 followers and 29 questions.
It seems to me as it could be easily replaced using engines (12 followers, 280 questions). Furthermore, engines has chess-computers as a synonym, which seems to me quite similar to computer-chess.
Should computer-chess be deleted / marked as synonym?
To my mind, computer-chess refers to the chess games played by computers (or rather engines or chess-computers as you noted), so they are referring to slightly different things. So probably the questions should be re-tagged because one of the tags has been misused.
I noticed computer-chess is frequently misused on questions about programming engines. I do not see why we need the slight distinction between games between engines and discussion about engines, as how an engine plays is an integral part of discussion about engines. I believe the tag should just be a synonym for engines as noted in the question.
