I just played this live 19x19 game in which I lost: https://online-go.com/game/17744867
I am mostly interested in the first 50 moves or so. I find it especially hard to deal with attacks like the one my opponent launched in move 13 (and again in move 39) where my corner stones are sorrounded. I have had problems dealing with similar situations in previous games as well.
Any advice would be greatly appreciated!
