If we are just training online for OTB games then it doesn't really matter if it is through playing 100% legitimate opponents or legit play mixed in against occasional engine assisted efforts but it is good to understand the difference between human play and engine assistance. Computers can't be "psyched out". If I want to play against an engine I will just use Fritz with the Stockfish engine. I don't lose sleep over engine users but I prefer to play humans as chess is potentially a very social game. I think my OTB rating will be higher than online when I return to OTB at my club soon. Online chess has had a great net benefit to my play despite my misgivings about engine use.
