I remember thinking that perhaps it is less severe to try to attack the 4-4 stone as it is easier to run (the classical era theory of Shi Xiangxia said that this is bad as the 4-4 can't make much territory anyway, so no point playing here), but pros these days see this as powerful.] ;W[de]C[instead, it places extra value on follow ups against the 3-4 stone, compare game 13.] ;B[ce] ;W[df] ;B[cg]C[this is an extremely common shape, and pros have considered it even. But perhaps this judgement needs to be adjusted - it is as if W played first in the corner (should be important), but it is as if W started on 5-3 which probably isn't optimal. Master repeatedly showed that this W group is very hard to attack and there is no urgency for W C17. The key is that B is pressed low in sente, and B has to play several slow moves to follow up locally, whether D17 or E13, both seem slightly less effective than if B responded to E17. Since B still has the C14 cutting weakness pinning the shape down. Ke Jie did say when he played D13 in this joseki vs Iyama that it was too slow and overconcentrated in that game.] ;W[dn]C[and now this is the natural choice, as B's left is low already, especially with D13 so it is easy to make it overconcentrated - I've suffered like this against leelabot. There is no point attacking C6, so the focus is on making good shape for the centre and bottom.] ;B[dm] ;W[en] (;B[co]C[continuing play on the left seems slightly questionable] (;W[cp]C[this shape is a big tight for W, but Master seems to agree that it is best (it was considered inappropriate by Shi Xiangxia) W's has to accept shape problems as W tenukied the approach] (;B[dg]C[the left side is too small I'm afraid] ;W[iq]C[the choice of pincer is interesting, compare games 30 and 58. It looks logical as it is a big point for the left and right bottom and seems perfect to restrict the movement of F3 (and hence help out the D4 group)] (;B[fg]C[the problem with B's shape is B has to keep protecting slowly or W plays here and it is hard to attack W as B still has the C14 weakness.] ;W[hc]C[solid - now D15 is completely light.] (;B[em]C[a bit frustrating if B keeps feeling he has to protect.] (;W[gp]C[this seems like the proper move, accepting this bit of territory and solidifying. W dodges B's intention. But W's shape weaknesses mean that W's area is not so big (just like the C14 weakness means B can't grow the area so big), but at least all W's moves make sense globally as these repeated protections work well with the lower side territory/potential, while B F13 is floating in the centre. So the feeling is that unless tenuki of the C6 approach is wrong (and the price is too high - having to spend so many moves to capture F3), then W should be slightly ahead.] (;B[qn]C[natural] ;W[np] ;B[do]C[natural when B is unlikely to move when W support is at O4] ;W[ep] ;B[eo] ;W[fp]C[W territory locally isn't too big despite spending extra moves to protect and both sides are overconcentrated, but J3 also adde s potential to O4] ;B[qq]C[natural as awkward to directly build the right] ;W[qp] ;B[rp] ;W[pq] ;B[rr] ;W[qr] ;B[rq] ;W[fn]C[interesting exchange, prevents B spending one move at G6 to capture the stones, grow the left and reduce the W area] ;B[fm]C[now if B G6 W has the aji to save to stones] ;W[qf]C[approaching from the bigger side, no real potential on the top with F13] ;B[qh]C[natural] ;W[nc]C[fascinating to see Master's choice here.] ;B[pf]C[I think Master often sees this shape as bad for B as it doesn't handle the territory well. It sees R14 for R12 as a good exchange (it aims to sacrifice R14 but leave B solid but overconcentrated)] ;W[qc]C[this looks like an excellent result locally ending with a shape I have never seen before] (;B[pc] ;W[qd] ;B[pe] ;W[qe] (;B[pb]C[this sort of move looks a little weird (is this worth anything?), but it is very standard. The point is otherwise W gets this, O17 is easy to sacrifice, and B still has shape weaknesses. This way round forces W to fix B's weaknesses. But ... I have my doubts about this move especially in this position. The shape just feels slow] ;W[qg] ;B[pg] ;W[kd]C[nice!
