This was my 2nd league game from the ASR League.
I tried to play as serious and well, as i could, so i won't regret anything.

Comments and thoughts appreciated

Just a few quick comments. Haven't been able to go through the whole game yet.

Mv 17: There's a continuation that starts with O6, I believe. Like so:

Not sure if that helps at all (I'm not even sure the sequence is played at all anymore), but it's an interesting sequence to study.

Mv 27: I would try one of H17, C14 or C12. Just suggestions. They seem to be weak points where you would have an easier time invading and living.

Mv79: I think your best bet is to connect at J4.

Your invasion at move 27 is probably playable, but it is not really related to the rest of the board. Since you said you were unsure where to play at this point, here is an idea -- try to come up with a strategy which makes efficient use of your other stones. In particular, can you make the stone at N9 useful? How about extending to O15 or N15, starting to make a moyo in this area. If W responds passively at M16 or M17, keep expanding with something like L14 or M14. Note that W was quick to play O15 himself as soon as he had a chance.

I think the game was lost at strategy. Always check which groups are weak. Harrassing them around the board will get you points and power. On the other hand defending your own weak groups by building bases and maintaining connections is just as important. This is quite different attitude compared to "just" grabbing points wherever. Notice the strength build-up between C3 and D3 exchange at moves 47 and 48 and how it later allowed white to invade H3 with no trouble at all.

Some comments in SGF format:
