Katago tells me W is slightly ahead.] ;B[pi] ;W[pj] ;B[oj] ;W[qj] ;B[ol] ;W[nk] ;B[ok]LB[qk:B][nn:A]C[I didn't want to let the black stones basically connect with a move like A, so I jumped out here, but it's best to just connect my own stones. After I jump out, black can split my stones with B and can handle the fight.] (;W[mn] (;B[ph] ;W[qh] ;B[pg]C[This is the the first fairly big mistake by either side, and the moment I started feeling ahead. This would normally be a forcing move, but W can connect while forcing the corner with S15. After this move W is leading by 4.3 points(72% winrate) ] ;W[re]LB[sb:A]C[After this move the corner can be captured with the monkey jump at A.] ;B[md]C[B probably felt just defending the corner was too submissive and wanted to get some moves in first. B never ended up defending the corner so it's also possible he didn't realise it could be captured with the monkey jump.] ;W[ne] ;B[lc] ;W[lb] ;B[kc]C[B seems to be pressing W down, but W has the ladder and can capture the two stones or the N16 stone.] ;W[ld] ;B[me] ;W[kd]LB[jc:A][mf:B]C[A and B are miai.] ;B[dm]C[B tries to play a ladder breaker, but the fight in the top/center is much bigger and there is no way I am going to answer.] ;W[mf] ;B[cm]C[B follows up on his ladder breaker, but...] ;W[lk]C[After this move the B stones in the center are in trouble, and I felt very much ahead. W+13(95% winrate)] ;B[cq]C[B played again in the corner, but the center is much bigger.] ;W[mi] ;B[mm] ;W[nm] ;B[nl] ;W[ml] ;B[om]LB[nn:A]C[It's possible to avoid the subsequent ko here by connecting at A instead of capturing, but the thickness from capturing is worth it, and is also the recommended AI move.] ;W[lm] ;B[pn] ;W[pm] ;B[oo]C[B does get a ko to save his stones, but it is very heavy on B and w has little to lose.] ;W[po] ;B[le] ;W[jc] ;B[pn] ;W[nn] ;B[qm] ;W[po] ;B[kb] ;W[jb] ;B[pn] ;W[ce] ;B[pl] ;W[be]C[B won the ko and rescued his stones, but the upper left corner is plenty and W is still comfortably ahead. W+20 points, 99% winrate] ;B[go]LB[lo:A]C[At this point I thought about capturing the upper right corner, but B would likely try to get the whole bottom side with a move like A, which I didn't like. I felt significantly ahead so I chose to play a game I was more comfortable with.] (;W[lq] ;B[jq] ;W[bk] ;B[bl] ;W[dk] ;B[ek] ;W[ej] ;B[dj] ;W[di]C[B wanted to fight, but I decided to sacrifice the two stones to build the center. ] ;B[cj] ;W[ci] ;B[bj] (;W[fk]C[I tried to get a bit too clever here, it would be better to just block at B11. The reason I played this atari was that if I played it after the B11, C9 exchange B might decide to capture the stone instead of extending. However, B played the counter-atari which is a good move. ] (;B[ei] ;W[el] ;B[eh] ;W[bi] ;B[ck] ;W[bg] ;B[fj] ;W[gj] ;B[ek]C[B gets another ko here, but again it is much heavier on B, and I still felt very much ahead.

W would however still be ahead even before komi. ] (;B[gh] ;W[sb]C[B didn't live, so I capture the corner and B has no chance of coming back after this.
