Life In 19x19

Again, thanks a lot everyone especially "Dusk Eagle"

All comments help me a lot

14: This is a bad shape, play P17 instead.
70: Just connect at D2 instead of descending.
152: Black at K12 kills that group. See Crane's Nest .

The game hadn't ended when you passed, you needed to close off black and white's borders before passing.
Other than that, you're playing well for a 23k ...

I have playing go for around two month
This is my second 19x19 game with human in KGS.
(I played black)

my opponent gave me 4 stones handicap.

please help me improve my game.

Many thanks!
