What openings feature Be2/7 and Bd2/7?

I'm not really big on opening theory. I usually just play dynamically in the openings, and according to my engine, I do fairly decent. It seems that I usually "win the opening" - or at the very least, I seem to get what I want and feel comfortable playing.  But I think it's time to start studying some openings. I seem to do pretty well whenever I end up playing Be2/7 and Bd2/7. And whenever I analyse these types of games, they seem to be a lot more solid and concise than my other games. So I'd like to start there. I know I will probably get responses like "you should learn this irrelevant one or that irrelevant one first" or "you shouldn't focus too much on openings" but I'm pretty set on studying this line/theme/position/whatever.

In short, are there any openings that feature Be2/7 and Bd2/7 in their mainline?

P.S.  I like closed, complex games.   If you can't answer my original question, maybe you know some good openings to keep a game closed up?

QGD and Philidor.

Fianchettoing via d2 or e2 isn't really a good idea.

To answer your question. Almost all openings have lines where those squares are occupied by the bishops. In fact the only openings where those aren't common, are double king's pawn (1.e4 e5) openings, such as the ruy lopez or king's gambit, although even those might find the bishops on the afore-mentioned squares. Especially on the black side. If you want closed ones, I suggest you take a look at some d4 openings. If you happen to like e4, then you better hope for a sicilian :)

Actually there are a lot of openings where a black bishop ends up on e7 (Closed Ruy Lopez, many d6/e6 Sicilians, the French, the QGD, several other defences to 1.d4, etc). There are fewer lines where white's bishop goes to e2 (because white often has the option to develop it a bit more actively at d3 or c4), but for instance in the Open Sicilian it's always an important option.

D2 and d7 on the other hand, are a lot rarer. Why block the queen's line? There must be a specific reason in the position to put a bishop there.

 Good point. But I usually play something similiar to the ponziani. Playing c3 allowing my queen to sneak out onto the queenside. Maybe this is a bit weak, but at the level I'm playing at it seems to work for me pretty well.

I will take a look at your suggestions, though. Thank you.

 I think you're getting rank and file confused. I'm talking about putting both bishops on the center squares. But I see how that would be an easy mistake. 2 and 7 would be finachettoed if the board was sideways.

 Not studying openings, I've found that I have been pretty much been playing something similar to the Ponziani, only leading with d4 instead which usually leads to a fairly closed game.

You said almost all openings have lines where those squares are occupied? Do you have any specific examples. Just from a preliminary search, I haven't really seen what you're talking about.

But maybe I haven't seen what you're talking about because I don't really know of any good resources for studying openings.
