This game ended closer than it should have. By mid-game black had a huge moyo/territory and I barely got away with invading it. If someone could give me some tips on how to improve my opening, or the early part of the midgame, I would be grateful.

Edit: Got a good review here: https://online-go.com/review/268907


In this opening, right side is more important than the corner.
