Chessbase 12 came out back in November.
You could check out under the notation pane when you open a game. If you click on a certain move it will bring up games with that move played. Also, look at the statistics, if you're studying from the black side and white has an overwhelming winning percentage, do not choose that move.

Hi all. Where do I start with Chessbase 11?? It's so massive! Specifically I want some help with transitioning from openings to middle-game. I find I'm not too bad tactically, but sometimes I have put myself in such terrible positions by the time the middle game comes, I'm defending the rest of the game. I know beginners shouldn't study openings too much, so I'm trying to stick to just a couple: the Sicilian and King's Indian defences as black, and Ruy Lopez and queen's gambit as white. How can I use chessbase to most efficiently get a grip of these openings? Thanks for any advice in advance.
