chess souces and database

I 've been playing chess for a while, however never gave much notice / care to learning openings, strategy etc, and until a few weeks ago played for the fun of it, doing what i think best at the spur of the moment. however i have lately started trying to learn a few known openings, the possible pre-studied options and reactions in a given, many times repeated position.
looking for a chess database where i could check on a particular position where i feel i did wrong, or could have played better, to see what s recommended.. or as in the attached picture, a database with a percentage of wins for a given colour on a certain move. 
came across 365chess, however although it s described as a database, statistics on the given example are just on 2 games, hardly enough to form a solid judgement on the strength or weakness of a position. 
are there any alternative sources i could look into? 
here s an example i was interested in, after playing the albin counter gambit, where white, instead of taking with a pawn, plays Nc3... i m trying to think and look into the best ways of taking it from here (playing black) in the opening moves. 
besides sources, even recommendations on the game, from that position, would be appreciated. 
thanks
