Hello, in this game I had the impression that I was a long time following the moves of my opponent, but during the game I could not find best moves. When I played in R13 I wanted to play R14 but at the time I thought it could not be a good idea later regretted, what do you think? I know there was a snapback during long time, but I played the game faster than usual and'm just not paying attention to this detail

Sorry, was actually Black at B13.
And R13 was actually 146.Which snapback ?

Accurate details are helpful for the review process.
