C[This game against Gu Li features 3 of Master's favorite moves, Black 5, 7, and 11. While playing opening moves that seem to indicate a big moyo strategy, Master doesn't seem to be trying to surround, but goes more for control of the flow of play. ]
MU[1];B[pd];W[dc];B[qp];W[dp];B[np]
C[Black's big shimari works well with a fighting game, being closer to the lower side as well as forming a wall towards the right side. It has not been popular because the corner is not yet Black's territory (see var). However, that changed immediately after the 60 Master games, and now this shape can be seen in top pro games.  ]
(;W[fq]
C[This shimari from the star point has become popular in modern Go. ];B[gp]
C[This shoulder hit is similar to the Go Seigen style. Black is not taking local profit but is trying to control a large part of the board. ]
;W[fp];B[ce];W[ci];B[ed]
C[This move pressing down on White was played by Honinbo Dosaku with great success, but later lost it's popularity as pros began to think that the territorial loss was too big. In various positions, Master played this move in about half of it's games. ]
;W[ec];B[fd];W[gc];B[gn]TR[gp]
C[Black 15 is the natural continuation after 7 (marked). ]
(;W[qj]
C[White enters the right side to prevent Black from making a big moyo. ]
;B[dm]TR[ci]
C[Black enters the left side, threatening to attack the marked White stone. ]
;W[ei]TR[dm][gn]
C[The marked Black stones are not completely connected, so White is probably planning to attack here next. ]
;B[cp]TR[dm]
C[Black plays to reinforce the marked stone. ]
(;W[do];B[co];W[cq];B[dn];W[bp]
C[White plays hane to take sente. ];B[bo]
C[Since Black has a very strong shape in the lower left, I question W20 and think Black has a slight advantage now. ]
;W[ef]
C[This is a shape move (see var). ]
(;B[gd];W[hc];B[hd]
C[Black seems to ignore the cutting point (see var).]
(;W[id]
C[Instead of cutting for a trade, White is trying to attack the entire Black group. ]
;B[ie];W[jd];B[je];W[kd];B[fc];W[fb];B[gb]
C[White must choose which side to play (see var). ]
(;W[hb];B[dg]TR[gb:hb]
C[The marked exchange has secured Black's connection (see var). ]
(;W[eg];B[dh];W[eh];B[bh]
C[This was a chance for White to play the vital point and pull ahead in territory (see var). ]
(;W[df]
C[It is difficult to explain why White played this move. After this ineffective move Black quickly took control of the game. ]
;B[eb];W[ga];B[cc]
C[Black connects to the center while gaining eye space in the corner. ];W[dd]
;B[de];W[db];B[ee]TR[bh]
C[The marked stone might look too far away, but actually it is connected to the main group, giving Black an efficient shape (see var).]
(;W[ch];B[cg];W[cf];B[bf];W[bq];B[gj]
C[With 57 Black starts to surround from the center. The UL corner Black group is already alive, so Black's plan is to push White against that strong group. The game is already very difficult for White.]
;W[hh];B[hi];W[ig];B[jh];W[jg];B[kg];W[kf];B[kh]
C[Black forces White to play dame points while taking control of the center. ]
;W[el];B[ck]TR[fm]
C[Instead of connecting at the marked point, Black finds it more efficient to take the side territory, and White's eye space. ]
;W[dk];B[bj];W[gl];B[gh];W[gg];B[il];W[bi];B[ai];W[di];B[bg];W[qm];B[pm]
C[79 is asking White to decide the direction of play with this move. The main threat is that Black is trying to build territory in the center (see var). ]
(;W[pl]
C[White plays 80 to reduce Black's potential in the center. ];B[qn]
C[When White plays towards the center with 80, Black can play 81 to reinforce the corner. ]
;W[ol];B[rm];W[ql];B[qf]
C[Black has more territory, and White's group in the center is not completely alive. After this Master continues to play thickly and wraps up the game with no dangerous fights. ]

C[The 1-2 exchange is good for White, in that White has gained territory in the corner while forcing Black to play a dame point.]

C[If Black pushes through at 1, White can cut with 2 and squeeze to 9 with sente. This is good for White.]
