Opening Explorer is open for use in Play?

I noticed that when you are playing a game, this comes up:

And if you click the button on the right, the opening explorer pops up. That's not very fair to let every have a quick link to all the best theory for that opening. After all, it completely negates anything you've done to learn openings, because you can just use that. They should remove that whole thing from play, because it ruins longer games if you don't want to cheat using it, and it's practically uncatchable. Was this on purpose, or is this a bug that will be removed?

It should be available in correspondence (which Chess.com needs to call what they call "daily" for better accuracy), but not in live, which appears to be the case in your screenshot.

Live chess is trash

No, this was a game in play. I agree, @Ziryab, it should only be available in correspondence. 

It shows there but you shouldn't use it. Not sure exactly why it shows there though. At most it really should just show the name and not be a link until the game completes.

Yeah, that's what I was thinking. 

The opening explorer appears, but the "book" icon does not appear to be an active link. I clicked it after we were clearly on our own and no information became available.

Yes, that's another odd thing. 

Telling you the name of the opening and the moves already played is not a new feature. Nor is it inappropriate in any way.

I mean the button to the RIGHT of it. You have to be in play, but then if you click the explorer button it brings you to the page with all the variations of the opening. 

This button is inactive

Yes, I know that button is inactive. The one to the right of it isn't inactive.

Both probably should be inactive.

Exactly.

Indeed, it's nothing new.
