;B[pd];W[pp];B[dc];W[dp]C[Ni-ren-sai.];B[df]LB[ce:A][de:B]C[Odd. A or B seem more common, but I like it.]
;W[jc]LB[cn:A]C[Splitting move. A was my other option and these are also Leela's 2 moves.]
;B[lc]C[Yes.];W[gc]C[Good.];B[le]C[Okay.];W[je]C[I have to do this, protect my group.]
;B[jq]C[No approach, but a splitting move. ];W[fq]C[I make this enclosure. I don't need to pressure him too much already here.]
;B[nq]C[A bit far, but it could work.];W[qn];B[pr];W[pj]LB[qf:A][qk:C][qq:B]C[I wanted to play B, first, but then I needed something quicker. I played my move, though Leela suggests an approach at A. My move is not on her radar, probably inferior in some way.]
;B[qq];W[qf]C[Yes! Leela likes it.];B[qe]C[Leela wants that stone at R16. I agree. This makes me stronger.]
;W[pf]LB[pj:A]C[Now A is at the right spot, thanks black!];B[cn];W[cl]LB[bp:A]C[This okay, though maybe protecting my corner would also be good. (A)I didn't want to give black a sphere of influence over the entire left side, though.]
;B[en]
(;W[ch]C[Okay.];B[cg]C[Bad habbit from black.];W[dh]C[Thanks!];B[bp];W[cq]C[Yes. I live very small now.]
;B[bq]LB[jc:A][pd:F][df:E][pj:D][cl:B][en:H][dp:C][ip:2][nq:G][br:1]C[Okay let's analyse the situation. There are already 8 groups in play. According to my radar these are\:A. Not hot but okay for now.B. Same. Can be invaded, so can't be surrounded.C. Close to being surrounded, can find life but need to keep an eye on it.D. Flexbel (is this even one group?)E. Can be invaded, but okay for now.F. Fine for now.G. Strong.H. Strong.Knotwilg\: you can extend your analysis to an assessment of mutual strength. In my opinion, C is your weakest structure, because it is closest to being surrounded. H is Black's weakest group because it has almost no base. So, taking the mutual base at 1 seems strong. Another idea is leaning at 2.If not there, I have two moves on my radar\: see variations]
(;W[no]TR[pj][qn][no][pp]C[Why then this move? I had some trouble and didn't want to spend all my time on one move so this was an instinctive move. Make the area harder to invade, build that right side, contain the lower side of black.]
;B[ql]LB[pl:A]C[And black immediately invades. Usually I would play A now. That would be a mistake, I think.]
;W[ol]C[A&D tought me a few tricks and I've been using them more lately. Cap, best move says Leela.]
;B[pm]C[poking the elephant's eye.]

;W[nl];B[oo]C[Leela has this as an even game.];W[on]C[Good.]
(;B[op]C[Mistake.];W[nm]C[I have this great move that connects my groups and splits black!]
;B[qj];W[qi]C[Good.];B[pi]C[Aggressive.];W[qh]C[Just stay calm.];B[pk];W[oj]C[Stay calm.]
;B[ok]

;B[nk];W[rj]C[Too small. 2nd line.];B[qk];W[qm];B[pl];W[jo]LB[pk:B][pn:A]C[Time to change the game plan. I was not happy with my play so far. Black has the lead in "territory", My influence is strongly reduced by black's stones. One thing I failed to see at this point is black's big weakness of the B group, we'll come back to that. All I saw was my weakness of the A group.]
;B[po]C[What? He wants that one stone? He can have it.];W[qo];B[qp];W[np];B[pq]
C[Got some free moves out of it.];W[mq];B[lq]C[Clamp.]
(;W[lp]C[Leela has me at 80% to win at this moment, though. But this starts a bad sequence for me.KW\: corrected your var]

;W[ko]C[After these couple of horrible moves, I'm 60% to win.];B[hq];W[hp];B[gp]
C[Black is just fearless.];W[gq];B[ho];W[ip]C[But that doesn't mean it's the best line of play.]
;B[iq];W[go]C[Good move.];B[gr]C[Wasteful.];W[fp]C[Yes. Now this group is connected to the other group and I'm super strong.]
;B[fr];W[jp]C[Timesuji.];B[kq];W[mh]TR[nj][qj][nk][ok][pk][qk][pl][ql][om][pm]C[So let's start the attack on the marked group! I'm strong enough to attack it now.]
;B[hn]C[Black doesn't see what's happening.]
