C[fishku: have a good game!
fishku: I tried to set komi to -20 to make the game even, but it seems negative komi is not possible on OGS. should I pass or do you want to try with 9 handi again? It was pretty close last game (before the corner problem)

C[fishku: yes, it gives you common corner sequences, sometimes with comments

C[mft0: I don't get anything for our corner, or maybe I don't know how it works
fishku: no, you're right, f15 is not in its book. It's not the best source for this kind of stuff, but it's fine for some ideas usually
fishku: doesn't matter so much :) all good go players will tell you you shouldn't learn sequences by heart and play them blindly

C[fishku: good move (maybe you just copied it ;) ), but it kind of punishes l17 which was a bit too far away from o17 I think
fishku: if I had played M17 instead, I could just ignore N16 now.

mft0: Where could I have copied it from?

C[fishku: where's the mistake that you mentioned? I think after E12, the variation I posted above is the best result for black, and E12 was itself the mistake. Not a large one though, rather an "overplay".
]
(;B[rf]
C[mft0: A12 was at least bad reading on my part, since I missed something obvious.
mft0: I probably missed something a lot earlier, but I don't think it was that bad since I had to read pretty far ahead at that point to see it.

C[fishku: Try to play sente moves before gote moves (moves that require me to answer vs. moves that don't require my answer)
fishku: I'm deliberately playing a gote move here (g5) to give you "sente"
fishku: although it is a pretty big gote move (g5) :)
mft0: I don't understand. You didn't play g5.
fishku: sorry for the confusion, it's a conditional move
fishku: I expect j7 immediately
fishku: :)
mft0: Playing j7 now makes sense, but I don't get what the point is for me to play g5 over e6?
mft0: I also think that I checked my own side well (famous last words), so I played for the most points now.
mft0: (with L14)
fishku: okay. for example, L14 was gote. You could have played l16 or o16 instead, which both are 1-point-sente moves
mft0: ok, that makes sense, but I thought it might be good to keep my threads for the end in case we get in a ko
fishku: I see. later in the game, ko threats are usually 0-point sente moves. They require an answer, but they make no differenc in score (if both sides answer)
mft0: threats*
fishku: for example, s3 would be a 0-point sente for you. if I respond at t1, it makes no difference to what the territory there is now
mft0: right

C[fishku: [object Object\]

(;B[kd]
C[fishku: so towards the end, all of the sente moves that make points should be played first, in decreasing order. It's a bit tricky since very large gote moves are sometimes preferrable to smaller sente moves. It depends on the difference between "result when black plays first" and "result when white plays there first"

(;W[lc]
C[fishku: however the rule of thumb is "sente before gote, big before small"

(;W[eh]
C[fishku: yes, good
fishku: there are many difficult concepts that Japanese players developed to solve these "endgame problems", like here: https://senseis.xmp.net/?Tedomari
fishku: however I would find an exact mathematical model easier. But it seems there is little material on that besides some research papers.
fishku: in summary I'm not really great at the endgame ^^
fishku: it seems like game theory has somewhat permeated go theory, but was simplified in some cases into "rules of thumb" and "sayings"

C[fishku: correct, this is ko! well done.

C[mft0: Thanks for the game. A new high score for me : )
fishku: gg!
fishku: [object Object\]
fishku: lol I'm 10k now
fishku: ah no it was just a glitch
fishku: anyway I had a look at the game and I don't see any huge mistakes that cost you the game as a whole. Mostly it was just local inaccuracies in play that allowed me to chip away at the difference in score (of the 9 handicap stones)
fishku: I am going to point out a few better variations in the review, but they're mostly local (not in the "global direction of play" sense).
fishku: One thing you could probably improve is to play less "puppy go" where you follow me around on the board. Feel free to find your own biggest moves if you think the move I played is too small to respond to -- aka being more aware of "gote" moves from my side!
