C[the weakness of the high extension is that black can scoop out white's eyes with a placement at A]
;W[qf];B[ok];W[oi];B[fq];W[hq];B[fo]LB[cq:A][cn:B]
C[A or B are more common continuations here for black];W[dn];B[dr]
(;W[kq]TR[dr]
C[the slide with the marked stone -- a move that Go Seigen liked -- is intended to force an exchange for white A at the 3-3 point, after which black will pincer at B (L4), so the slide makes an extra eye for black ]

C[the lower side is settled; after this, the left and upper sides are large]
;B[cl]
C[black chooses the left side to have potential to attack the lower left white group]
;W[fn];B[gn];W[fm];B[eo];W[cm];B[dl];W[dm];B[ch]
C[this reinforces the black group, preparing to attack white's lower left group]

C[white strengthens his group, but it's not yet completely alive];B[db];W[cc]
;B[fe]
C[black puts pressure on white's upper left corner, expanding black's upper side and helping his left side group as well]

C[white can also play at A (O15)];B[ne];W[nd];B[qh]LB[lf:A][qc:B]
C[instead of the game move, black can enclose white's upper side group with A, but white can probably live with B, so with this invasion, black is trying to get some forcing moves so that he can make the enclosure work]
;W[qc];B[rf];W[rd];B[re];W[rc];B[ng]
C[in this trade, white has gained in the coner; in return, black has an attack on the white side group]
;W[rg];B[qg];W[rh]
C[white squeeze the two black stones to connect the rest of his group];B[ph]
;W[oh];B[og];W[mi];B[pf];W[pi]
C[although this is an even trade territorially, black has gained because white now has a weak group. I think this is where black takes a lead in the game]
;B[bf];W[be];B[fk]
C[black secures his left side and is hoping to pick up some territory in the center while he attacks white]

C[black has a secure lead at this point; even after paying komi he's about 10 points ahead and in fact, the final margin was 9.5.
