Analyzing your games is the best way to impove.
First when i was noob i play only catalan and dragon only but then i improve myself by playing stockfish and i beated stockfish 4 very badly when and then when was of 9 years i drew with stockfish 6 which was a winning endgame as i have a rook and king and it have a king and a bishop but now that account is now close.Then i started playing with fritz which is on chessbase it's a tricky engine and stockfish is good for solid solid chess.My advice is that first play with stockfish and then with fritz.
