BG: The moves that I'd like feedback on the most are moves 23, 81, and 85.];B[pd]BL[43];W[dc]WL[55];B[pp]BL[35]C[T: two mistakes in two moves! ;-)];W[cp]WL[45];B[ep]BL[29];W[dn]WL[43];B[cq]BL[26];W[bq]WL[42];B[dq]BL[25];W[bo]WL[40];B[iq]BL[24];W[qn]WL[35]C[T: My usual habit has been to just invade without asking first. but since I have been in this exact position before and seen that Leela prefers to approach here, I decided to try that...];B[on]BL[513]C[BG: I wanted to try something new and this move just kept nagging at me. So, I gave it a try. If felt like it worked well with the marked stone.]TR[iq];W[qq]WL[572]C[T: Baffled by the P6 move and not finding any immediate flaw with it - I do what I do when having no idea what to do... invade the corner!];B[pq]BL[409]TR[iq]LB[qp:A]C[BG: I also consideered A. But I've got the marked stone already so this seems like the better direction.

T: I was happily surprised by this, since I thought the other direction would have been a little better - my R6 stone is pretty silly in that case.];W[qp]WL[570];B[pl]BL[388];W[pr]WL[566];B[or]BL[387];W[qr]WL[565];B[oq]BL[354];W[jp]WL[544]TR[io]C[T: that bottom side looks too big .. don't know what's the right place to reduce. Maybe the more standard J5 manouver would have been better?]
(;B[jn]BL[311]C[BG: Defending at A was clearly to passive. I figured this move would result in the start of a wall along the marked areas. In retrospect, I prefer B. See variation. ]TR[gn][hn][in][kn][ln]LB[kq:A];W[io]WL[276]C[T: black says my stones are killable - are they?];B[in]BL[301];W[go]WL[267];B[hp]BL[290];W[ho]WL[246];B[ip]BL[206];W[jo]WL[236]C[T: Was a bit worried that I had taken more than I can chew off here - and opponent is making me heavy is a scare sign!];B[gm]BL[175]C[T: Expected F6 instead];W[fn]WL[213];B[gp]BL[312];W[ce]WL[332]C[T: too small? D10 or K16 better?]TR[dj][jd];B[jd]BL[300];W[qc]WL[328]C[T: No questions (approaches). Just take the corner!];B[qd]BL[283]C[BG: Downwards is bigger.];W[pc]WL[326];B[oc]BL[281];W[ob]WL[324];B[nc]BL[280];W[nb]WL[324];B[mc]BL[279];W[mb]WL[324]TR[rd]C[T: trying a new variation, since the hane at S16 would make black's right side stronger. Which is note ideal since I am planning to invade there when I get sente ro do so.];B[rc]BL[268];W[rb]WL[300];B[lc]BL[226];W[hd]WL[237]TR[rd]C[T: Debated S16 instead, but decided it was too small];B[dj]BL[194];W[dh]WL[216];B[cm]BL[188];W[cn]WL[89];B[em]BL[122];W[fm]WL[221]C[T: misread here, did not see that his D5 in a few moves would be atari.];B[en]BL[149];W[eo]WL[210];B[do]BL[127]C[T: misread this atari when I pushed F7. Thought I could play E8 atari and then D4 here.]TR[el][dp];W[fo]WL[206];B[dp]BL[126];W[co]WL[140];B[fl]BL[97];W[el]WL[138];B[dm]BL[597];W[gl]WL[600];B[fk]BL[586];W[hm]WL[599]C[T: really worried about my group here]SQ[gl][hm][fm][fn][fo][eo][go][ho][io][jo][jp];B[il]BL[557];W[hl]WL[565];B[ik]BL[547]TR[hn]C[T: Need H6 to get even one eye];W[jq]WL[556]TR[lo][lp][mp][mo]C[T: Maybe a jump (to triangel square) would have been better, but thought this move is almost a threat against black's marked group]SQ[gp][hp][ip][iq];B[lo]BL[453]C[BG: This was a mistake. I thought it was worth the lost stones on the left, but looking at it now, I think A would have been better. White still lives, but I get a more secure group on the bottom left and I likely still get my wall in the area of the stone I did play.]LB[ir:A];W[fp]WL[538];B[fq]BL[449];W[ir]WL[537]TR[gq][gr]SQ[gp][hp][ip][iq]C[T: expected a triangle play instead. Thought black missed the danger the marked group was in. BG said afterwards that it was a calculated sacrifice.
In my judgement, keeping white's heavy group without two eyes would have been much preferrable for black. Was still worried about it, and it can be bullied around.];B[hr]BL[448];W[gq]WL[533];B[gr]BL[438];W[hq]WL[531];B[er]BL[437]C[T: and my group lived in sente!];W[ig]WL[408]C[T: stake out some territory and push towards black's area];B[kg]BL[421]C[BG: This move I'm very uncertain about. Whites stone is reasonably placed, and not easily threatened.];W[bm]WL[404];B[cl]BL[368];W[qi]WL[220]C[T: time to invade, considered several spots, but in the end I wanted to threaten the slide to S8.]TR[qh][qg][pj]MA[rl];B[qk]BL[357];W[re]WL[206];B[rd]BL[277];W[qf]WL[195];B[rg]BL[176];W[kf]WL[256]TR[qg]C[T: time to try out that cross-cut magic I saw a lesson on.. alternative was R13];B[lf]BL[263];W[lg]WL[249];B[kh]BL[246];W[mf]WL[237];B[le]BL[238];W[oe]WL[236];B[od]BL[233];W[mh]WL[209]C[T: invasion is going better than expected!];B[pe]BL[185];W[pf]WL[196];B[ng]BL[164];W[og]WL[164];B[nh]BL[169];W[oh]WL[152];B[ni]BL[105];W[rj]WL[87];B[qj]BL[51];W[rk]WL[191];B[rl]BL[45];W[rh]WL[165]C[T: I think I am alive now];B[se]BL[19];W[qg]WL[123];B[gc]BL[512]TR[db][dd][cc][cd][fc]C[BG: I now have to do something to reduce this area. Wasn't sure what the right way to proceed was.

T: I fully expected something like this. Personally I would adhere by the saying to create aji in the corner before invading, and playing a triangle move (D18 maybe) first before invading at F17.];W[hc]WL[585]C[T: my gut feel is that this invasion is desperation and should die.];B[dd]BL[478];W[cd]WL[577];B[cc]BL[471];W[ec]WL[483];B[gd]BL[388];W[he]WL[454]TR[ge]C[T: Probably hane is more severe];B[de]BL[280];W[df]WL[402];B[ge]BL[322];W[gf]WL[375];B[ff]BL[284];W[gg]WL[333]TR[fe]C[T: gut feeling was to cut, but did not see how that accomplished anything but giving black an eye];B[ef]BL[252];W[ee]WL[328]TR[dg]C[T: Probably a mistake? Maybe triangle would have been better to confine black. There is no eye in there.];B[dg]BL[247];W[cf]WL[314];B[fe]BL[332];W[ed]WL[278];B[eh]BL[330];W[fg]WL[356];B[eg]BL[310];W[gb]WL[346];B[fb]BL[302];W[ib]WL[344];B[fc]BL[299];W[gi]WL[174];B[bg]BL[158];W[cg]WL[139];B[ch]BL[260];W[bh]WL[137];B[ci]BL[258];W[bi]WL[241];B[bj]BL[254];W[bf]WL[232];B[nf]BL[237];W[cr]WL[218];B[dr]BL[229];W[mr]WL[217]C[T: too deep too low?]TR[mq][lq][lr];B[lq]BL[222];W[lr]WL[206];B[kq]BL[214];W[kr]WL[202];B[kb]BL[204]LB[sb:A]C[BG: We both missed this until later in the game, but this is sente for the group on the upper right. Black A is a serious problem.
T: Actually B T18 is met by S19 and white should live. More about this later.];W[oi]WL[164];B[oj]BL[192];W[mq]WL[145];B[mp]BL[186];W[ko]WL[141];B[kn]BL[598];W[lp]WL[598];B[np]BL[586];W[im]WL[579];B[jm]BL[582];W[jl]WL[578];B[kl]BL[573];W[ln]WL[575];B[mo]BL[572];W[jk]WL[551]C[T: misread this ladder, only reading that I will encounter friendly stones - not realizing those stones are not rescuing white.];B[jj]BL[567];W[kk]WL[531];B[lk]BL[564];W[eb]WL[287];B[fa]BL[559];W[gk]WL[273];B[fj]BL[544];W[gj]WL[266];B[fh]BL[536];W[fi]WL[259];B[ei]BL[526];W[ke]WL[219];B[kd]BL[513];W[me]WL[215];B[ld]BL[505];W[ki]WL[202];B[ji]BL[477];W[hn]WL[244];B[kj]BL[455];W[gh]WL[218];B[so]BL[425];W[ro]WL[268];B[sn]BL[417];W[qm]WL[256];B[ql]BL[413];W[sp]WL[251];B[rm]BL[409];W[rn]WL[225];B[sm]BL[390];W[po]WL[199];B[oo]BL[386];W[pm]WL[153];B[om]BL[378];W[pn]WL[151];B[sb]BL[285]C[BG: I think this kills white.]
