Life In 19x19

Hi there,

I've played this game yesterday and I really would love to receive some feedback about it.
This game got my attention because I did a lot of mistakes (more than usual), some situations I didnt know how to respond, and I think I got lucky that my opponent didnt punish my mistakes.

My mainly questions are the following:

Should I have approached at O3?
How should I have responded?
How should I have punish that stone? Playing at E5 for example?
white 216: How soon should I have approached that group? Is this the best approach to kill that group? And W218 at S10 would be enough to kill that group?

I added some comments in the sgf about what I was thinking at the time. Any comment, suggestion, is welcome.



Thanks

A few comments, then.

Play at C18. Black has two ways to play atari on the C15 stone. This makes one of them, C14, into a bad play. So Black can only play E15, which is not scary.

makes sense in the overall position. Influence in the centre diminishes Black's formation at the bottom.

Play F16, Black E17, White D18, Black E18, White F18 for a good wall. (E18 can be F18, but this isn't better for Black.)

looks like an overplay. There is a proverb "beware of going back to patch up". You're not going to have time to fix the cut.

After some mistakes by both sides. Play J18 and then K15 for reasonable shape here. F3 ad O3 are just about miai, so your overall position would be fine.

Hi Charles, thanks for the comments.
I guess for I just freaked out. I shouldn't do that when I see something different or that I don't understand.


Hi S2W, thanks for your insight.
I couldn't see at the time the position to kill the right side group. Later today I will try different ways to play that san-san invasion on the bottom-right.
