If you want low-study positional you're gonna need a few opening systems that are usable against many different responses.
As black I'd consider looking into the Dutch Defense. I've recently dropped it due to a few emberassing losses straight out of the opening, but it IS solid and requires basically no study...
As white... well, I play the KG.. that's not a 'low study' opening :P.
Another black option (although a little bit less versatile) is the Nimzo-Indian ... which is great for an endgame player being as black spends most of the midgame simply trading off pieces in an attempt to create multiple sets of doubled pawns ... it's a fascinating opening system because white just can't get moving in time. I've been using the Nimzo for the past week (in replacement of the Dutch) and I love it.
Just my 2 cents :D

Since I have started playing chess, I have always played the King's Indian Attack as white, Pirc against 1. e4, and King's Indian Defense against everything else.
These openings have served me well, but for various reasons I think it's time to move on.
I am not at the level where studying openings extensively is the best return on investment. So, I am looking to find a set of openings which requires very little theoretical knowledge and can give me more study time for tactics and endgames.
However, while I definitely want to avoid the mainlines of the ruy lopez and sicilian, I do want solid openings.
My playing style can best be described as dynamic/positional with a penchant for endgames.
So far, I am thinking of the English Opening for white. I will play the early g3 line moving for a fianchetto. This seems somewhat like the KIA that I am used to but much more ambitious and well-rounded. I thought seriously about this compared to the Bird/Polar Bear system (reverse Leningrad dutch style) and decided that was just too risky of a game for my style.
As black vs. e4 I am really liking the Scandinavian Defense with 3... Qd6.
Black vs. d4 is where I am drawing a blank. I guess I could just keep the KID, but honestly it's the one that I'm the most uneasy with. I am thinking possibly the Dutch Stonewall, but I really don't know what my options are other than indian systems.
Does anyone have any input or other suggestions?
