Hello everyone! Nice to meet you
New here to the forums (though I did register a little over a year ago), and thought that having my very own thread on Go would help me focus better (a persistent problem which needs to be vanquished!) and maybe even a few words from the community to point me in the right direction too.Some background: I discovered the game of Go sometime during the winter of 2008 while I was living in Hokkaido. I did not know what the rules were or even what the game was about, but standing near a table momentarily watching over someones shoulder as they placed their stones... it looked oh-so fantastic. Such geometry! I wanted to learn how to play and to understand what was going on, though it would take me nearly half a decade!! before I actually sat down and did anything about it. I am currently in my third year of a physics degree, so my time for Go is somewhat limited unfortunately. However I will do what I can. My experience is a single solitary year of experience consisting of mere short packets of "real" playing and learning, probably clocking in at around half to one month total learning/playing during that year. Until now, I have only studied some Tsumego (via the Android app Tsumego Pro). So no Fuseki or anything like that. Yet. Maybe soonish.
So here I am, now posting my first message on lifein19x19. This is not a study journal chronicling my long journey to shodan or any such thing. I will try progress naturally with no goal in mind. It's simply to help me improve my understanding and quality of game
of course it's always easier to see afterwards, the hard part is noticing in the game. Keep playing and you will improve rapidly.
The last four moves are a bit wild. They don't work together at all, and especially Q6 is very self-defeating. There are now four solitary white stones for black to harass. You might want to read something like Otake Hideo's "Opening Theory Made Easy" to get a general feel for it.
The standard move here is R5 or R7. It gets you into a fight, but that's the fun part.
P7 is better, here. If black plays P6 after, maybe you get into a fight, but playing P6 yourself is surrendering.
A little bit like 
This is fine, but you should have done more to run out at some point.
Your invasion is alive, but N13 is threatening to shut in that group in the middle.
Yeah, that would have been better.
Connect!
You can play at B11 now.
How about S13?
Helpful to white. It's better to play at H14. It puts G14 in atari and threatens a ladder for H15, which doesn't seem to work, but if white then pulls out to G13, you just ask "which of these two?" again by playing at H17. F15 is really a very precarious stone.
D15 catches it
C3 would protect most of that corner.
Was this really worth more than K2?
Q3, seriously. Playing P4 here screams "I HATE CORNER TERRITORY!"
White invades the right side, but black does not care.

If they're dead, but you can still make forcing moves, save them until you either have a ko fight, or maybe until you have a very clear idea of how to save 
Not needed, they're already caught.

White has established a right-side group, essentially without having to fight for it. Yay white! Maybe you shouldn't have ignored it up to now.
Q6 is not purely defensive. You'd still threaten to cut off those stones, so white would have to respond to save them. If white plays elsewhere, you could just push in at O9 and they're in trouble.
Not needed, they're already caught.
Not needed, they're already caught. You are aware you can't be cut off at O16, right?
Not yet forced, and there is still a point!
