C[Locally, this is not the best move for White. This time, it's a good move. See what would happen if White played elsewhere:]

C[It is usual for Black to finish the joseki on bottom left, but this time sente is much more important. See what would have happened if Black played at B]

C[This was probably Black's mistake. The move makes pressure on White's group, but it is also slow. Black could have kicked with A, White would have answered with B and Black would have jumped at C. White's group is still under pressure and Black is faster. Another option for Black was to simply tenuki at D.]

C[It is necessary to play here, otherwise White could have played this big move in sente.]

C[White can't cut at B. See variation]

C[This is a keypoint for eyeshape of Black's group.];B[dn];W[gn];B[fn]
C[Maybe it was better for Black to play directly here instead of A. White would have played B anyway. It is questionable whether the exchange A for C is good for Black, but after the game I feel, it was not a good exchange for Black.]

C[So far, White is doing good in the game and Black must do something.];B[no]

C[Black's hane is another mistake. It would have been better to extend up at A.]
;W[np];B[mq];W[nn];B[oo];W[on];B[op];W[qn];B[pm];W[pn]LB[rp:A]
C[It would be too painful for Black to play at A now, which would capture White's stone in the corner. Black has to try something different.]
;B[mn]LB[mm:A]
C[If White plays at A now, Black will secure his corner by taking White's marked stone. And Black will probably manage to survive on the right side without big harm, which will lead to an ok result for Black.]

C[Black is dead on the right side. There is a few step ko, but it is unplayable for Black. After this, Black tried to make a miracle, but it did not happen. White's position is too good here.
