Wow! This was a really dangerous game. I started off trying to swallow him - but only at almost the last move I realized I am lacking of liberty - and my opponent will be swallowing me up sooner or later (at the upper right corner). Then I change my mind and decide to defend the left hand corner and hope to get a part there - and I am not sure what is my vital point, resulting in me losing that whole territory. Lastly, I have no choice but to defend my last corner - bottom right, which I did, successfully - and gain only about 20 points there. It was quite a nice game - but opponent was, how to say it... aggressive? (not sure if it's the correct word). Anyway, hope the reviewer could give me some ideas on my weakness, and thanks to reviewer in advance. :)
