I lost and I feel I could learn from this game

https://online-go.com/game/3338448 I couldn’t really understand what my opponents opening was so if someone could explain if it a viable opening or if he was going easy on me.If someone could review this I would be very grateful. Thank you for your time.

Yeah, it looks like the player was messing around. The idea was to take some 40 points on one side and then make certain you didn’t get that anywhere else. It’s not a good strategy, and I think you picked up on that, but mistakes in the middle game are far more consequential than opening mistakes, which is why some players choose just throw in the towel and start having fun.
