I only play correspondence chess as I want duplicate OTB play as closely as possible.
I play daily too, but do not feel it duplicates OTB play. For example some of the complicated stuff that I play in daily would not survive OTB because it walks a narrow line, and OTB would not be able to calculate far enough to steer a clear passage through the complications.
Have tried playing 30 minute games etc online, the trouble is that without the opponent sitting opposite I do not get that adrenaline from being in a battle, so just become bored and mind wanders.
Perhaps the best way to simulate otb would be to play daily, always setting position up on a real board and making decision without touching any of the pieces. Might try that out in a tounament
Chess.com is the only chess I can get. It's not perfect but it is very good. I find I get conditioned by looking at all the facilities in chess.com where I just make auto responses and seem to lose the capacity to think. This happens in games and I find myself down in a game. Then I start to think and usually retrieve the situation to a degree and give a better game or sometimes win. Unless I'm bored I stay away from live chess and play daily stuff. I've started entering matches and tournaments and it gives a better discipline.
Set up your games on a real board and pieces.
