How to Set Up A Particular Position and See What the Computer Would Do

Hi everyone. I'm still new at Chess.com, though I've played some games, and practice with the computer a lot, and analyze my games. I want to develop a little before going right out into a bunch of real players, because I'm quite nervous because of my brain injury.

Anyhow, I'm still learning how to use Chess.com's list of many features, and one that I don't know yet, I could really use right now.

I was learning about the Jaenisch Gambit opening for black if white sets up the Ruy Lopez with you. I learned a few responses to typical moves, but then the computer did something probably pretty good (as in not some crazy reply that doesn't make sense), and it was different than I've practiced.

So I tried a few different ways to respond to this new response from white, but found myself very much on the losing end each time. I'd like to take that position that I keep getting into and see how the computer would handle it, what it would recommend?

Is there a way to set it up specifically and analyze it, trying different options in practice format, sort of? 

Thanks in advance, and also for all the help so many of you are giving!

Assuming you are on the website

Mouse over to the left and place your cursor on  "Learn"

Then choose "Analysis" 

Then set up the board any way you want. 

Since you have premium membership, you can also choose "Learn" -> "Openings" and see what the masters have played before.

That works great to set up the board, and see what other players have done by percentage, but I was wondering if there was a way that I could try out lines and see what the computer does with them? Rather than just the typical next response after the last move in my set up position.

Is there a way to have it set up and see what the computer recommends next? Like what the best move would be?

Never mind I got it. I set up the board position to put in moves, then set up a practice against the computer in the other tab. I can change see try moves on the analysis board and transpose them to the practice board to see how the computer would respond when I do different things. Thank you, this is soo helpful!
