I started playing Go for about two weeks, and right now, I am slowly learning how it works.
Right now, I am starting to have a losing streak. So, I thought maybe someone can tell me what my strengths and weaknesses in this good(?) game.
I would tell you this : play often and review your games. Watch other games (maybe around 10k? Some would say to look at higher strength games… I don’t know.)
You played well for someone who is into Go for about 2 weeks Keep it up !
You could try to use the OGS feature “estimate score” to see what the engine thinks is your territory. It is usually wrong (absolute value) but gives a good idea / better visibility at your level.
In general, you played much too safe during your game, which is why your opponent got to play annoying moves. My advice would be: play fearlessly, crash into the wall, and learn from it
For black 79, try C3 and eventually win the game if you defend the inside correctly.
