I've been playing on lichess.org for my online games, and is the primary way I enjoy chess. One of the big reasons why I started playing on lichess.org was that they offer a simple way to export your games from their database into pgn format.
So far playing casually I have logged over 250 games at this point and downloaded the pgn files. I'm interested in getting some statistics out of this data. Is there a chess database application that I could use?
The primary goal of analyzing these games en mass is that I want to identify my strengths and weaknesses with my game openings. For example I enjoy playing the queens gambit, but I'd like to know my win percentages with it. Which ECO codes I am currently struggling with, which variants am I coming against most often? Am I truly a tactical player? or a positional player?
I believe that the data can help me identify trends in my game that I am currently unaware of.
I already use engines like crafty and stockfish to help me analyze individual games, but I'm having difficulty finding tools to help me analyze my entire collection.
