My main advice after this game: find higher ranked players, like a 9k, to play even handed, even if it is for a free game. This opponent didn't particularly challenge you, apart from the non-spotted atari. You completely outplayed him technically and strategically.
Improvements to make14 & 18: hane to the contact play; we should not play blindly but hane against contact play is often the best choice and here it is
52: principle 2 - surround first, then play at the vital point
56: a group with 1 eye will die too; there's no need to keep it to 0 eyes
Good stuff80: Your fighting spirit is awesome. Indeed, not giving up is the first prerequisite for winning.
140: the fact you start looking for the middle shows flexibility and whole board thinking; great devices for winning!
154: playing cautiously when ahead is a great way to win a won game
166: You say "Still, I feel this is an opponent who's happy when he can eat one stone. So if I can give that to him and distract him, it's okay."
This is exactly what I mean with making your weakness your strength. You are "opponent aware" and don't play the board. The bad side of this awareness is that is leads to anxiety. If you can use this to outsmart your opponent because you are aware of his thinking or even his feelings, then you are making it your strength.
210: high level tactic
240: the way you emotionally deal with Black's madness shows you have greatly improved, also in your mental state

;B[qd]C[My opponent is black.]
;W[dd]C[And I'll be white for today!
]
;B[cp]C[Crossgame, awesome! I've hardly ever played crossgames.]
;W[pp]C[So in unfamiliar territory. I decide to go with 4 - 4 twice. I feel 3-3 here would also be a good choice.]
;B[qn]C[Black approaches.]
;W[od]C[And I approach.]
;B[jd]C[A very large pincer. Well, does it count as a pincer? It's an extension/pincer sort of thing.]
;W[ld]C[I'll put some pressure on it.]
;B[fd]LB[fc:A]C[Good. Low was even better.]
;W[cf]C[The safe move.]
;B[gq]LB[np:B][nq:A]C[Black could have made a double approach on my corner, but he didn't. Great news for me!]
;W[pf]TR[ld][od]C[Oh. During the game I wasn't looking at that yet, apparently, instead I make a double approach. Seems okay, because these 2 stones are not the strongest.]
;B[qf]LB[qg:A]C[Black reacts. Note that he could still double approach me. If I attack his corner stone than, he can do the same.- to mine.]
(;W[pc]C[Leela likes the hane, but I go for this. It feels like a good shape.]
;B[qc]LB[pe:A]C[Black at A would've been good. This is okay.]
;W[ql]C[Now I pincer black's approach.]
;B[qp]C[Odd move. How to react to this?]
(;W[pn]C[I attach. I'll have the outside if I can.]
;B[po]C[Yes. Bulge]
;W[oo]C[Atari.]
;B[qo]LB[qq:A]C[Connect. And now Leela says A, but it seems risky. I defend instead.]
;W[on]C[Seems okay. Leela has us at an exact tie at the moment.]
;B[pq]C[Good.]
;W[op]C[I'm strong, black has the corner.]
;B[rm]LB[qm:A]C[Why not A? So submissive.]
;W[qg]C[Not severe enough to react to, so I go elsewhere.]
;B[rf]C[Balck cowers a bit.]
;W[pg]C[I stay strong.
KW: good]
;B[rg]C[Okay, but small at this point.]
;W[qi]C[I react to it, though.]
;B[ri]C[I don't feel this is the right timing.]
;W[rj]C[Hane.]
;B[si]LB[qh:B][rh:A]C[Very odd. A or B.]
;W[cj]LB[hd:B][qq:A]C[So I take another big point. Though Leela likes A and B best.]
;B[dm]LB[dc:A][oq:B]C[That stone high is not the best. Low was better. A or B even better. White is definitely ahead now.]
;W[ej]LB[hd:B][qq:A]C[Slow move. Still A or B according to Leela.]
;B[jj]LB[jj:1]C[Watch that stone. It's going to end up beautifully. Not a good move, obviously.]
;W[hd]C[Hey, I looked at some invasion points yesterday, so let's go for it!
I mostly went over an invasion when one stone is low and the other high, but still, it's practice!
KW: perfect!]
;B[hc]LB[dc:A]C[Seems legit. Leela prefers A, though. This move is not on her radar.]
;W[gc]C[Good.]
(;B[ic]C[No...]
;W[gd]C[Okay that was good. I isolated that stone. My corner is still a bit open, though, so be wary.
KW: perfect!]
;B[fe]C[He's gonna run with them.]
;W[hf]LB[fc:A]C[Now this surrounding is not the best. A connects my stones and takes away his base. Much better.
KW: no, I like your move better. You are strong in this area so you should split his stones]
;B[fc]C[He wants to connect.]
;W[gb]C[I won't let him.
KW: very good.]
;B[dc]C[Good.]
;W[cc]C[Have to.
KW: good]
;B[db]C[Safe move.]
;W[cb]C[Defend the corner
KW: more importantly: reduce his eyespace]
;B[fb]C[He's very concerned with living.
KW: understandably so!]
(;W[ea]C[I poke a bit at his eye space.]
;B[da]C[Defends this way.]
;W[fa]C[So I connect that way.]
;B[eb]C[A bit odd.]
(;W[ed]C[MAybe this is odd, too.
KW: remember, a group with 1 eye is dead too]
;B[ga]C[He takes.]
;W[fa]C[I was concerned with making a false eye, here, but this is not the best move in these circumstances. Black can still get out and can now maybe connect back to his other stones.]
;B[id]C[He threatens to surround me.]
;W[kf]LB[gf:A]C[Bamboo joint was better.
KW: yes]
;B[gf]C[Take it away.]
(;W[gg]C[No. This is no good. My stones aren't particularly strong either. I have to help them out.]
(;B[fg]C[No.]
;W[ge]C[Yes, this is okay.]
;B[ff]C[Okay.]
;W[hg]C[And defend, good.]
;B[gh]C[Better to do the one point jump.]
(;W[kb]C[So I started going after this group instead.
KW: good idea, bad point]
;B[kc]C[Okay.]
;W[lc]C[Good reaction.]
;B[jb]C[He's threatening to make eyes.]
;W[kd]C[That one is no eye.]
(;B[hb]TR[ia]C[He could make one eye there.]
;W[ha]C[Not now.]
;B[ia]C[Good, ko.]
;W[jc]C[Big mistake.]
;B[ga]C[Because black takes the ko. And I suffer from blindness temporarily. The one-eyed fool is back in business. I was looking too locally at that group, that I missed...]
;W[ka]C[I missed...]
;B[he]C[This! Now I know what you're thinking: white is out of this game. It was a setback, I'll give you that.
But I learned to never (well, seldom) give up. I can still make something of this game!]
;W[jf]C[Not the best place to start but it keeps my stones connected and still strong.]
;B[dg]C[Black starts harassing me, but a bit too nice.]
;W[cg]C[Thanks!]
;B[cd]C[Doesn't work.]
;W[ce]C[I take it.]
;B[bd]C[Doesn't work.]
;W[bc]C[He's dead.]
;B[ca]C[Comes in the corner.]
;W[be]C[Atari.]
;B[de]C[Odd play.]
;W[ee]C[Push once.]
;B[df]C[He extends.]
;W[dh]C[Hane.]
;B[eh]C[Block.
What Leela is showing me most of all though, is that this is not a hot area.
If I can learn to judge the whole board better, I think I'll increase a lot more. I have to make a comeback once again, and this is too slow a play to do so. If my opponent were stronger, he'd take away some big points and it'd be over.]
;W[di]C[Safe, but slow]
;B[ef]C[Atari.]
;W[ad]C[So I take.]
;B[ec]TR[bd]C[Atari. I could leave it alone, not worth a lot of points. But the fact that I can't retake immediately worried me a bit. (no stone there)]
;W[cd]C[So I chickened out.]
;B[fi]C[Luckily my opponent is still worried about his group or something? He makes this incredibly slow play.]
;W[iq]C[There we go. Comeback time.
KW: great!]
;B[jp]C[Black doesn't want me to live.]
;W[ip]C[I do want to live.]
;B[jq]C[Not the best shape!]
;W[jo]C[Hane.]
;B[ir]C[Hane!]
;W[in]LB[hr:A]C[Shape. Not the best, though. A was better.]
;B[ho]C[He peeps immediately.]
;W[io]C[And I connect.]
;B[hq]C[Good.]
;W[hp]C[I push.]
;B[go]LB[gp:A]C[He extends. I don't know why he doesn't just block.]
;W[gp]C[So, hey, let's push again.]
;B[fq]C[Huh. He extends again.]
;W[fp]C[So let's keep pushing!]
;B[fo]C[Okay.]
;W[ep]C[Push!]
;B[eq]C[Extends.]
;W[dp]C[Push! (it's like giving birth)]
;B[dq]C[Extend!]
;W[dn]C[Hup, a jump!]
;B[en]C[Hane.]
;W[co]C[Hane.]
;B[bp]C[Extend.]
;W[cm]C[Good shape.]
;B[dl]C[Extend.]
;W[bo]C[Slow.]
;B[fm]C[Yeah, black needs to make his group a bit stronger.]
;W[lp]C[Now we come back over here.]
;B[kr]C[Black makes sure he's connected.]
;W[oq]C[And I do this, threatening the corner.]
;B[pr]C[Good.]
;W[or]C[Extend.]
;B[rq]C[Slow! Let me take advantage!
Already Leela has given me the advantage back! Actually she made things even at move 112 already.]
;W[lr]C[I do this.]
;B[ko]LB[kp:A]C[Hane. I considered A and now I see Leela suggests it. See variation why I was hesitant. But like the variation shows, I'm okay.]
;W[kn]C[Soft.]
;B[lo]C[Okay.]
;W[ln]LB[kp:A]C[A is still legit.]
;B[mo]TR[ld][od][jf][kf][pf][pg][qi][ql][in][kn][ln][on][oo]C[Good. At this point, though, I started looking at the middle. I decided it would decide my game, how much can I get in the middle?]
;W[hl]C[Let's find out!]
;B[hm]C[Good.]
;W[im]C[I do this. And I think my opponent was blinded a bit, too. He thought I was attacking his group (which is only half true) while I am actually just building the middle. His group can live for all I care. It's not that big.]
;B[hn]C[See? Very, very safe and slow.]
;W[hk]C[A bit slow, too, but strong.]
;B[gl]C[Okay.]
(;W[hj]C[I could turn, but I wanted to isolate that stone from his buddies, this does that, I think. See variation.]
;B[fj]C[He wants to connect both groups. Fine by me, go ahead. I'll just take the middle.]
;W[hh]C[Good point.]
;B[hi]C[Now it's too late to save that stone.]
;W[ii]C[There.]
;B[gi]C[He connects and I want to squash the aji of that stone.]
;W[ij]C[Leela doesn't necessarily disagrees, she has this move marked, too.]
;B[ek]C[Oh black, your group is fine. Stop worrying about it and make bigger moves!]
;W[ck]C[I play it really safe now. At this point I consider myself having made a great comeback and if I can play it safe albeit a bit slow, I have this game.
KW: playing cautiously when ahead is a great way to win a won game]
;B[cl]C[Push.]
;W[bl]C[Stop.]
;B[bm]C[Atari.]
;W[bk]C[I decide he can have that stone. My left group is more important and should stay safe.]
;B[cn]C[He takes.]
;W[do]C[And I connect.]
;B[eo]C[Why?]
;W[mn]C[No way for black to come into my beautiful middle!]
;B[mp]C[You want to eat that stone?]
;W[mr]C[I'll give it to you. I just want to avoid trouble.]
;B[lq]C[If he wants it so bad.]
;W[mq]C[Just take it.]
;B[kp]C[There. Careless play by me, though. I should've read closer to see if I can safe that stone. Sacrificing is okay, but meaningless sacrificing is not.
Still, I feel this is an opponent who's happy when he can eat one stone. So if I can give that to him and distract him, it's okay.]
;W[qm]C[Good point.]
;B[rl]C[Good.]
;W[rk]C[Great!]
;B[qh]C[Good.]
;W[ph]C[Atari]
;B[rh]C[Defend.]
;W[qj]C[Just staying safe. I don't want any weaknesses in my center.]
;B[sn]C[So slow and unnecessary.]
;W[qe]C[Okay then. Overplay, though. Leela says black can swallow it.]
(;B[re]C[I'm lucky.]
;W[pe]C[And strong.]
;B[qa]C[Is this a move?]
;W[pb]C[I don't know.]
;B[qb]C[Connects.]
;W[pa]C[Necessary. Leela approves.]

;B[je]C[Good.]
;W[ke]C[Close it off.]
;B[if]C[Good.]
;W[ig]C[Atari.]
;B[ie]LB[jj:1]C[And connect. Look at that middle. And now take a look at that stone from waaay back.
Wasn't the best move!]
;W[jh]C[Super safe, super slow move.]
;B[sl]C[Super unnecessary move. I guess it's worth one point so it's okay.]
;W[np]C[I can make some points in the bottom.]
;B[no]C[Fine.]
;W[nn]C[Block.]
;B[os]C[Nice.]
;W[ns]C[Got to.]
;B[ps]C[Ends in gote for black.]

;W[ap]C[Yeah, nice.]
;B[aq]C[Block. Do I connect now?]
;W[bq]C[Of course I don't. I got this.]
;B[ao]C[Black takes.]
;W[cq]C[Atari.]
;B[an]C[The best black can do.]
;W[ap]C[I take.]

;W[ar]C[Atari.]
;B[am]C[And connect.]
;W[cr]C[I made some points here!]
;B[dr]C[Black responds.]
;W[al]C[I play a super safe move, that's probably not necessary. Though it turns up slightly on Leela's radar, so I'll take it! Not a bad move.]
;B[bb]C[Okay.]
;W[ab]C[Good.]
;B[ba]C[Connect.]
;W[ds]C[Biggest move left.]
;B[es]C[Yes.]
;W[cs]C[Yes.]

;W[]C[And I pass. Game over, I think.]
;B[sk]C[Doesn't make any points.]
;W[pk]C[But I'll be super safe. ]
;B[sj]C[Doesn't make any points.]
;W[]C[So I pass.]
;B[ki]C[This starts off a mad attempt to break up my play. He's allowed to try, but I feel he should just accept his loss and stop here. It turns into this silly "fight" where he tries to exploit some weaknesses that aren't really there.
No more comments until the last move.]

It was a nice game and then it feels like my opponent couldn't face up to losing and made some weird moves and then resigns instead of just passing. I don't know, maybe that's just my way of thinking.
Anyway, good game. A big mistake early on and then a slow but good comeback. This time I didn't rely on my opponent's mistakes (I mean a big blunder), rather on my own strength to come back!])
