C[BenKyo Baduk: This atari is fairly slow. Black's shape is already extremely solid, so playing a nobi there and going after a relatively disposable stone for what will become even more thickness, is a bit slow and redundant. There are many examples of moves like this that are slower and smaller though, this one is kind of okay but definitely  unambitious

C[BenKyo Baduk: P11 - countering (get out, develop increasing pressure on black's weak group) instead of timidly responding at R9 just to protect a small number of points

BenKyo Baduk: This push is slow just like F15, once again adding solid to solid. Black is super solid already with that corner shape after adding Q16, and when you are solid you should use that solidity to play stronger, faster, more efficient moves. Add more solid moves just guarantees inefficiency

C[BenKyo Baduk: I planned this response earlier on. It feels like a big gain for black gaining M17, but white at least can now aim at D18 thanks to H18 supporting the F18 stone.
BenKyo Baduk: Long-term plan now: I can get K5 sente, do some chasing of the N8 group in the center, and do that in a way that will get me some stones closer to black's D11 area, enabling me to then reduce that place more deeply and more safely. That should be enough to win the game, since I have something like 70 points after komi and black doesn't seem to have a way to get that, and has a weak group in the middle.
BenKyo Baduk: ^ ^ ^ MY PLAN ^ ^ ^
BenKyo Baduk: After reducing the left-side black stuff, K2 will get big (L2 for black), and eventually R9 and C8. R9 should be black's sente if black times it will though, not playing it too soon. I expect black to get R9 and white S8, but if black does it right now I would consider ignoring.

BenKyo Baduk: E10 is normal, but not ambitious enough considering my lead, I suspect you aren't counting the score of the game (current black and white total territory)

C[BenKyo Baduk: Since there isn't that much to point out, you obviously played pretty well. The message is clear, you're falling behind just from sheer inefficiency from those two moves, there are some other things that lose a little bit but these are the main point I want to focus on
BenKyo Baduk: Already solid, don't play more solid moves from it
BenKyo Baduk: Here's the logic and how to understand stone efficiency:
BenKyo Baduk: When stones are spaced out to get points and potential, they're efficient. When they're close together, they're not. Thick/solid/close together formations are inefficient, losing points-per-stone. So why can solid formations be good? It's be USING them, like a hired army. If you pay for the army but then don't use it, or even worse, pay more and add more army for no reason, you move towards a very simple self-inflicted defeat
BenKyo Baduk: Think of it like this:
BenKyo Baduk: Solid formations of close-together stones start off lacking efficiency, like a points debt, and their value comes from how using their strength can recoup the cost, sometimes recouping it & more. You start out missing some points/inefficiency and you have to get them, whereas spaced out stones already have enough efficiency to win, and it's the other way around for them--it's the opponent who then has to take advantage of the thinness. The person owning spaced out stuff doesn't have anything to do, if left alone they just win (unless you build in the same way as them). If you make slow and solid formations and the opponent spaces their stones out, you literally just auto-lose unless you do stuff to recoup the missing efficiency of your stones. Fighting, stretching the stones out extra, stuff like that.
BenKyo Baduk: Think of solid formations as having a debt, a points/efficiency debt
BenKyo Baduk: They're like investments, ones where you're in control of the return.
BenKyo Baduk: Don't buy a $1-2,000 phone if you only use the call feature (lol?)

BenKyo Baduk: Your main thing to learn/study from this game and my comments is the deeper understanding of stone efficiency with regard to thickness/solidity. Scroll up to the horizontal line I posed above the most recent one, 10 or so messages above here

C[BenKyo Baduk: When my opponent makes a move in the very local tactical situation, I always think first of which move would affect the score of the game the most in my favor, then work backwards from there only if I have to. Therefore I will check this atari first, and verify it by checking what happens to me if you counter-atari right now at H16 
BenKyo Baduk: You have to make sure you think in this way too, and on your opponent's behalf especially. In other words, you have to expect this move when you play G15, it should be your natural fear and the thing you check first.
BenKyo Baduk: I say all this as guidance for how to think about where to play, but also because I'm not seeing what you're going to do to me to make up for the cost to your territory

C[BenKyo Baduk: This one (L15) feels like it's meant as a forcing move, but is it? I'm unable to see a variation for black that does something serious to me there.
BenKyo Baduk: It's fine if you just misread or misjudged something, not trying to critique you on that, more I want to make sure you have thought about it a bit, and if not, then I'm calling that out.
BenKyo Baduk: For example if you had played J15 atari, i was always going to counter-atari with K15 and sacrifice the one stone, to keep my center group connected to the top. So this L15 move doesn't enable a capture or anything like that, as it was already available
BenKyo Baduk: It doesn't seem like you can cut me off

BenKyo Baduk: (White M3)
BenKyo Baduk: and when white M3, it's also annoying for your bottom territory. O3 seems more important to me than the left side, even considering the empty space and build-up of black potential from E15 group on the left side
BenKyo Baduk: Left side is only one thing, points for me or you, and only one dimension of territory (left side only)
BenKyo Baduk: O3 can even go into R3 after, another benefit
BenKyo Baduk: So please take note of the main element here of white extending on the bottom creating a moyo. If you play O3 (or even N3), you end up not having to worry about any kind of moyo like that anymore.
