Opening practice/drilling against a BOT


I don't think there is a bot that will only play either E4 or D4 openings.
However, it should work if you use the analysis board. https://www.chess.com/analysis
Make the moves on the board and then press the finish vs computer icon down the bottom.
You will be taken to a game with a bot (you can change the bot if you like) where you will be playing either White or Black depending on which side moved last in the analysis board.
For example, if you want to practice the Caro-Kann as Black,
- Play e4 in the analysis board
- Click on Finish vs computer
and then you can play c6 as black with the computer.
If you want to practice the Caro-Kann as White
Play 1.e4 c6 on the analysis board
Click Finish vs computer
Then you are set up to play your response with the white pieces.
Hope this helps!

That is half way there thanks I'm going to give it a try straight away. I new I saw somewhere on here to finish vs Computer but couldn't remember where. I'm not good enough to be creating my own openings so I'm just trying to learn a few hours ones to get me into the middle game without being down a bunch of material or in the back foot defending. Thanks again!
