This game gets really complicated very quickly, with multiple eyeless groups fighting each other with predictably fatal results. ]

C[none of the groups are alive yet; it's a bit of a mess, really. this is the key point of this whole game: hard to see a way for White to recover at this point]
;W[jk];B[ij];W[ge];B[ed];W[ec];B[fc];W[fd];B[rk]
C[now the top B grp is alive, the top white grp has escaped, but the right-hand W grp is in serious danger, so B has the advantage]

C[the tenuki here is unusual; W wants to complicate things even further to create chances]
;B[cq];W[hb]
C[Wtries to attack B's grp but playing at A is better, to save the W grp in danger on the side.]

C[so W survived on the right but his middle left-side group is dead, the upper left group may die and the upper right group has to win a ko to live. Time to resign.
