;B[jc]C[UC: To tenuki here is bad. If Black is going to play here, he should have 
UC: omitted the sequence on the left]

;W[qg]C[UC: 42 was played to defend the corner while preventing Black from settling 
UC: himself easily]
;B[rh]C[UC: 43 is the losing move]
;W[kg];B[kh];W[jh];B[ki];W[ji];B[kj];W[gd]C[UC: 50 is well-judged]
;B[ig];W[jg];B[gb];W[op]C[UC: 54 is White's best guess]

;B[fo];W[dm];B[kp]C[UC: 77 is a nice move]
;W[kq];B[hq]C[UC: 79 works with 77 to help Black settle his group]
;W[hr];B[gr];W[hp];B[gq];W[or]C[UC: Playing 84 shows that White is confident of winning]
;B[nm];W[rg];B[hh];W[jj];B[dg]C[UC: 89 defends against the possibility of White A]

;B[ke];W[fb];B[gc];W[db];B[fa];W[eb];B[dh];W[dq];B[le]C[UC: 33 is necessary to maintain territorial balance after losing the top left 
UC: corner, but Black's bottom left group is now in great danger]
