Play computer against specific opening?

I'd like to play the computer here in order to practice a specific opening as black. 

Is that possible?  Do I have to manually set up a position a few moves into the opening and get the CPU to continue? How do I do that exactly if possible?

Failing that is there a way I can force the computer to play a specific opening as White so I can practice as black?

Try Learn>Openings.  Pick one.  Notice there are 5 little symbols just above the move list/frequency?  Yep, the one that looks like a laptop; click and enjoy.

Thanks, I guess I have to bump the computer level up a bit as it keeps making moves faaaar away from the main lines

There is chess software out there that even lets you start from a specific position, as well as making the computer play a specific opening.

I forgot the names, though, it's been a while, but I'm sure you can find them quite easily if you search (most are paid software, but there is 100% some freeware as well - I used one myself).

@baddogno thank you so much!!! this was a great feature to discover to help me learn!

Where do we chose which opening we want to learn? All I see is this:
Also it wont let me choose black.

I want to play against a chess opening too. I think Chess.Com should create this feature. It is an important way to improve your chess.

You can use this URL to practice openings with the computer : https://www.chess.com/practice/openings

You can choose to play as black or white.
