Life In 19x19

This is the first game I play with real player on KGS, before I just play in computer with Many Faces of Go. It seems to have a lot of capture. Please review it for me and critique the way I play. I am White


Thank you very much.

Thank you very much!

I have one question: In a match, when can I press and attack, and when can should strenthen my territory?

Yeah, thanks for the advice. I've been playing on 9x9 and 13x13 for a month now. This is the first game i play on a full board. I kinda suck at playing in the center.

P/s: Sorry for the bad English.

I just started playing Go recently and I don't know how to improve my games or how to review the games I play. This is the first game I play in the full board.
Please give me some advice to improve my game.
