Caro kann when to go Be7 vs. Bd6


im not an expert but i do play the caro kann, so if its an advanced variation then you develop it to Be7. but if not then I like to develop it to Bd6 when the opponent short castles and when a rook isn't staring down my pawn which is pinned,


I am not an expert but I have a few lines you can follow.

I believe you play Be7 when white is threatening imminent d5-break. When white has a Bf4 I would tend to agree that Bd6 is stronger because black simply must trade pieces, and a Bf4 is usually very annoying in such positions.

In the classical line is customary placing the bishop on d6 if you are going to castle queen side, which could be a liability if you are going to go kingside; f7 pawn could be defended by the queen in c7 in some lines if you 0-0-0, and the bishop on e7 have an eye on the knight on f6 and f7 doesn't need to be defended. Of course, this is just a general approach, and in some lines that could change.
A good way for you to research this, just gather a good number of masters games and do a comparison on piece placement, plans used and results. Leave Stockfish for specific lines, the more tactical the better, because detailed/niche variations by the engine are not going to explain you in words what's going on.
And of course, I can be wrong.

I think FM Charly has a good idea. gather some master games and do a comparison of pieces placement. you should start recognizing patterns and themes in the development. not to throw a monkey wrench in to the plans, but I have seen instances of playing g5 and Bg7.

In the classical line with h4-h5 probably that g5 isn't a good idea my comment was about that line. However, I have played some games with the line Nh3-f4 (or Ne2-f4) where the idea you mention was pertinent.
