A new year, another 365 days to play and learn Go.
To start the year, I had the fortune of finding a game against an OGS 1-dan player. I'm not gonna pass up an opportunity to play against such a strong opponent and we even reviewed a little bit.
I tried to play my A-game, obviously, and I think I might be able to learn a lot from the mistakes I made. So I hope others here will help me point out more learning opportunities!
Biggest mistakes:
creates two weak groups, or rather sacrifices a stone and gives a big corner for two light stones. not good enough. There's a variation to just live in the corner.
black can hane. but I couldn't read out the cut if black were to hane. I thought there was big trouble with the P16 stones being short of liberties. 
my shame. I totally misread. I only saw the ladder if white kept playing atari down and I thought I could take the four white stones. Now I don't know why I thought a 1-dan would play that knight's move in that case, but at the moment I was just trying to play the board and I didn't think about these things 
apparently also can hane. Looked dangerous to me, though, because of white G4 later and potentially a cut.I think from there it was pretty much lost. Another moment of shame when I played
thinking it was sente only to discover at 
that the ladder still wasn't broken. 
So for all my tsumego these last few weeks, here I go misreading the same ladder twice in a game. 
was the last real bad move probably. threatening the cut here was so insignificant.Moves I'm proud-ish of. After all, this was a 1-dan, and I didn't cower away. So I'm proud of my playing, too. I used my time very well, played slowly and considered every single move.
was well considered even when I played 
and expected white to split.
putting pressure on white. 
not taking the obvious atari. Although, come to think of it, the obvious atari is probably better but it looked like a cool sente move with a follow up I managed to read out, and that in itself is pretty cool to me. Knowing you're playing a defensive move and knowing you have a follow up so your opponent will have to answer and you can take sente is awesome.
even though it is probably wrong direction, I like my "fighting" spirit.
I think the correct shape move.
at the moment I liked it, but afterwards there was a ko and then I thought: was 87 a mistake because I wasted a ko threat? so probably not the best move after all 
white has a clear lead (about 20 points according to the AI review).
was a (minor) mistake. 
. 
A bit premature. Better to approach the bottom left corner.
Non-urgent. Approach the bottom left corner.
and the corner. If now 
at O-04, 
Attack while preventing the underneath connection.
Very bad. Surely you have to atari at M-14.
Good. You saw the light. 
How about D-05, the AI special. If White pushes through and cuts, go after 
. If White crawls, push once and then pincer 
Pincer. This play makes it easy for White to sacrifice 
Aji keshi, I think. In general, don’t play this push unless you plan to cut.
Nice shape play. 
Double atari, I think, to get the most out of the Q-03 stone. Surely White will connect.
