White plays away from Black \t in order to avoid being pressed too hard. ENDCOM B 2 o16 W 3 r8 MARK All \t@q10 All COM White 3. White pincers \t to try to establish a base. ENDCOM B 4 r10 MARK r8 COM Black tries to keep White divided. If White manages to connect all of his groups, then Black has wasted his 9 stones handicap. ENDCOM W 5 o10 MARK r10 COM White tries to connect. ENDCOM B 6 o9 W 7 n9 B 8 p9 W 9 m10 B 10 n11 W 11 n10 B 12 p12 MARK o10 p9 o9 n9 n10 m10 n11 COM Again, Black keeps White separated. ENDCOM W 13 g4 MARK p12 \t@o10 \t@n10 \t@n9 \t@m10 COM White again plays the two space high approach. He plays 13 here because of the presence of the marked white \t stones, which could act as a ladder breaker. ENDCOM B 14 k6 MARK g4 COM Black again keeps White separated. Now Black 14 would break any ladders around White 13 in favor of Black. ENDCOM W 15 c6 MARK k6 COM White tries another approach move... ENDCOM B 16 e5 MARK g4 k6 c6 COM ...and again, Black divides White 13 and 15.

ENDCOM W 49 g16 MARK c6 \t@o10 \t@n10 \t@n9 \t@m10 \s@g4 COM Another two space high approach, again here because of ladder breaking potential of the marked White \t stones. Also, if Black attacks 49 or \s, then White can run out towards the other. ENDCOM B 50 h15 MARK g16 COM This being the case, Black 50 hits White 49 and keeps him separated.

ENDCOM W 65 g7 MARK f13 COM White 65. Bold but necessary. If Black got to play here, he would wall off a lot of territory. ENDCOM VAR DIAGRAM SETUP B g6 MARK \t@g6 COM If White lets Black place around \t, then Black's territory is too large. ENDCOM ENDVAR B 66 j7 W 67 b9 B 68 c9 W 69 c13 MARK j7 g7 b9 c9 \t@d15 COM White uses the aji of White \t to extend to 69. That is, Black cannot allow White to connect 69 and \t, so White gains a tempo. ENDCOM B 70 d14 PRISONER d15 COM Black must capture or be divided himself. ENDCOM W 71 c3 B 72 d3 MARK d14 c3 \t@g4 \t@g7 COM White invades at 71, and Black crawls at 72 to keep the marked white stones isolated.
