I felt I had little choice but to make a moyo here. but I didn't expect Leela to think so poorly of it, W losing 3% compared to H3 at 54.15% for B, 3 mill sim] (;B[pj]BL[3510]TR[jq]C[leela thinks the lower side is more important, and I see the logic, having already spent a move at F3. This is worse by 0.6%] (;W[nq]WL[3497]TR[jq]C[leela thinks K3/4 is more of a shape point in this moyo game for both sides -2.5% compared to K4 at 7 mill sim this was also a slight surprise for me, I was more scared of K3] (;B[lq]BL[3485]C[shape is very important to leela, it is not a fan of this joseki -1.5% compared to K4 I suggest the appropriate proverb: "don't play so forcefully when attacking in your sphere of influence" I think leela uses this move mostly if it is trying to reduce W's area It strongly likes O5 in general against the tight pincer. I can appreciate the logic - to counter-attack B's aggression. But pros don't like it much as B gets territory and W gets outside.] (;W[qq]WL[3322]C[-3% compared to O5 B is already at 55.8%] ;B[qp]BL[3481] ;W[pq]WL[3321] ;B[op]BL[3479]C[here leela has a joseki reevaluation it expects O2 (like me), but thinks O4 is 2.6% better] (;W[nr]WL[3320]C[once again leela hates the 2nd line. In this joseki, S4 will be semi-sente (M2 aji), but there will be a cut at N4] ;B[mo]BL[3478]C[W can cut at M4 or N4, but leela's point is that this is small compared to having less issues around R7 (P3 liberty is free, and S3/4 is semi-sente) Most of the time pros appear to disagree, but I tend to trust leela more in the opening. It is a question of how much aji there is, and that is very hard, so it's not at all clear to me who is right in this case. (unlike with D2, which I am more confident leela is right to criticise) Still, the whole joseki overall felt good to me. Despite my dislike for moyos, my direction felt very good, W was too much in the corners. I assumed at the time the O3, R3 sequence was questionable, but if leela says it is more the fault of O2, I can believe that too. But I was also preparing to face pain around K3 later - it seems unprotectable] ;W[nc]WL[3316]C[I expected this, and so did leela, but it (she) thinks this is very questionable, losing 2.6% to J4, and over 1% to either R14 or R12 i.e. bad direction when F17 is low] ;B[pf]BL[3471]C[leela prefers O15 or P15 by 0.7%, but I'm not sure I will be copying that anytime soon] ;W[kd]WL[3313] ;B[me]BL[3284]C[I was a bit unsure about this move, but it was something I'd seen before. I couldn't say I thought it was the best possible move. 3 minutes Leela says F5 is more important to defend though it looked bad to me leaving invasions at H3, K3, but I guess sometimes you have to not die first Otherwise, N15 is near the top of the list. Also are: L14, M14, E16, P17] ;W[kf]WL[3260]C[This was a slight surprise (N16 expected), but I had felt W M14 seems shapey despite looking like an overplay Leela says 0.8% worse than N16] ;B[mc]BL[3234]C[This was guaranteed, but I needed to spend some time reading the many complications here (M17, N16, O16, O15, P15, Q17, R17, N14) but I could do that in my opponent's time. Soon this felt very good for B - W didn't seem to have a good way to save O17 without a huge loss on the outside, but if it died, it was abnormally big. I expected M17 or Q17 Leela says M17, R12, R17 good, Q17 nonsense] (;W[qj]WL[2876]C[what!! but leela says only -1% very tough to choose which side here, but ideally I wanted sente to take O16 (or M18 if daring) If I go R11 and can't kill, the O17 issue remains and my shape at N5 is broken leela prefers R9 as well by 0.5%] (;B[qk]BL[3139]C[I thought Q9 but didn't read, leela thinks it is slightly better than game] (;W[re]WL[2709]TR[qc][nd][qd][rd][qe][rf][qg][qi]C[oo! How do I punish this? I had been thinking about W R15 aji, but didn't consider this Next was a very difficult decision, I want to punish R10, but can't spend a move to kill it (it should have been my area anyway), but I don't want S15 to live too comfortably in the corner. I seriously struggled to find the best move. Eventually I told myself my reading was clear enough for my plan, so just take the corner. And to remember my pre-game plan to take territory But when I saw leela's suggestion of R15 after the game, it seemed so simple and obvious. Still, it is only slightly ahead of S16: 4 mill R17 56.83 R15 56.74 R16 56.42 S16 56.61 R11 56.49 S14 57.05 ] ;B[rd]BL[2876]C[leela prefers the R16 wedge by 0.5%] ;W[qi]WL[2649] ;B[rk]BL[2874]C[with support at S15, I can't hope to kill, so I should defend (my territory) first before attack, hoping it will live small, giving me solid outside, or run and give me solid territory.] ;W[qe]WL[2623] ;B[qd]BL[2872] ;W[qg]WL[2617]C[the weakness of S16 is the Q15 cutting point, though Q14 is hardly much misplaced now for a difficult decision: seal in and protect against O17, or chase into the centre and kill O17 naturally?] ;B[oh]BL[2054]C[This took 13 minutes, requiring lots of reading and judgement. The reading is about the cut at Q15 Normally I would have just ignored complicated reading and let it run (B P12 makes very few points since L14 reduces), but W P12 was particularly annoying against Q9, it really had to live very small (S10, T15 sente), and this was an important game and if I sealed with a good result, the game would simplify in my advantage, so the reading would be worth it. Leela thinks O16 protect is just barely better, but I am happy with my choice.] (;W[ph]WL[2506]C[though painful, leela agrees Q12 better than giving up O17 aji] ;B[og]BL[2010]C[I played this to be absolutely confident it was sente, but it is smaller in points than P11. Leela thinks I lost 0.3%] ;W[rh]WL[2442] ;B[rj]BL[1945]C[this seems crude like a computer, but actually leela isn't that fond of this move. I really wanted to probe if W would R14 or S11, this was very big anyway, and I was scared W would T16 in double sente which was big as it concerned the O17 aji] ;W[ri]WL[2316] ;B[se]BL[1879] ;W[rf]WL[2266]C[leela says B's chances are 59.27% g15 60.05 e16 60.26 f5 59.74 m17 59.10 m18 58.81] ;B[lb]BL[1825]C[I protected as I thought there were more issues than there really were and the corner looked so big (O17 is such a bad exchange) I wasn't totally sure it was better than N18 as now the aji of W L17 aims at N16 ] ;W[lc]WL[2120] ;B[mb]BL[1794]C[leela says L17 to take sente was much better (2%)] ;W[kh]WL[1770]C[once this was played, it looked really big, and I wasn't really sure I was in the lead I no longer wanted to play L10 as the aji around J4 looked really bad, so I should just play normally But the influence loving leela actually thinks this is a bad move - it suggests C12, K17, Q9, J4 as better] ;B[jc]BL[1728]C[but leela thinks this is too small instead, S3, E16, E9, G15/14 I see the logic - why reduce this territory when it is so painful for W to defend (reduction at G15, or peep K17 if L18) But it is bigger than it looks due to wedge N16 aji. If N16 now, I can defend at J17 ] ;W[pi]WL[1693]C[This seemed like a nonsense move, a bad exchange whatever I respond] ;B[oj]BL[1689]C[leela preferred p11] ;W[kj]WL[1678]C[leela wants L8 here now.

W made the centre group rock solid, but the shape is still weak, lots of peeps K11,13,15 Much better would be W using a weak shape to make lots of points in the centre from attack the left and using the double hane weakness. This is such a disaster for W. Now M9 becomes a good move - not only did W tenuki it, but also spent a move making an empty triangle at K9 to respond. Just ridiculous.] ;B[ni]BL[728] ;W[nj]WL[738] (;B[nk]BL[347]C[7 minutes to choose N11 or not, I thought S5/6/7 aji was too bad, and the local loss with O9 was minimal as I get sente] ;W[mj]WL[718] ;B[mk]BL[347] ;W[mi]WL[695] (;B[eq]BL[311]C[this offers the clearer endgame, without losing points] ;W[dq]WL[558] ;B[fo]BL[305] ;W[lr]WL[518] ;B[kq]BL[268]C[necessary] ;W[kr]WL[515] ;B[jr]BL[245] ;W[bf]WL[482]C[this basic endgame move was hard to believe.
