This move is just big, now W is solid, if W gets a move here, it is tough to invade] (;W[qf]C[a bit surprising, I'm not clear what this move means 1) R8 is abnormally far from Q16, and O4 means W is solid so W is in an attacking mood 2) on the other hand, alphago normally finds big points, to play, near the corners for efficiency, rather than spending moves on the sides trying to attack, as that doesn't work so well so, is this move urgent? are there really no bigger points to take? perhaps not] (;B[mo]C[what?? also, it is this slack move that didn't turn out so well this game? this helps R8 out while expanding the left so it is actually very natural. But somehow it feels like it is quite early to play in the centre like this, and after W settles inside, this move doesn't make enough territory. I don't know if this is the start of how B got into trouble. Perhaps I am wrong to say that B even got into trouble though, it's hard to tell] (;W[fq]C[this move now becomes much more natural and well placed given B has spent a move at N5 as B has a closer move at C8, W is happier to let B defend at D5] (;B[hp]C[if B is going to pincer anyway, does that mean a closer approach at F3 is better than at G4 or so? maybe] (;W[go]C[interesting idea W's result seems good enough] (;B[do] ;W[em]C[cool, not a human move] ;B[dn] ;W[ho] ;B[ip] ;W[io] ;B[jp] ;W[lr]C[B's shape is pretty rubbish (too overcentrated, but still no territory and few eyes)] ;B[jo] ;W[im]C[W's shape is much better for territory and eyes than the K5 group. What B got is to defend D5 and a solid corner territory in sente, but in turn W got M2 for territory, and the D11 weakness more obvious now W has stones nearby, so I'm not so convinced by B's strategy here but as usual, I not convinced by my own feeling W is happy ] ;B[qp]C[woah] (;W[qo]C[alphago says this is ok when B's support is so far away] ;B[po] ;W[qq] ;B[rp] ;W[pn]C[nice] ;B[oo] ;W[no] ;B[on] ;W[nn] ;B[om] ;W[pq] ;B[jm] ;W[ro]C[this seems a shocking tenuki initially, especially as B has a tesuji at R6 to make eyes but once W got S7, all B's groups seemed weak] (;B[il] ;W[hl] ;B[ik] ;W[hk] ;B[hj] ;W[gj] ;B[hm] ;W[in] ;B[gp]C[B gets this territory, it isn't so small despite M2, but] (;W[jn]C[B's shape is terrible after this] ;B[gi] ;W[fj] ;B[fp] ;W[fi] ;B[hi] ;W[fh] ;B[ci]C[still issues on the left area] ;W[km] ;B[qe] ;W[pf] ;B[nd] ;W[rm] ;B[pi] ;W[mf] ;B[fl] ;W[gk] ;B[rl] ;W[ph] ;B[oh] ;W[qh] ;B[oi] ;W[og] ;B[re] ;W[lc] ;B[mh] ;W[le] ;B[mb] ;W[eq] ;B[dr] ;W[fo] ;B[eo] ;W[lb] ;B[mc] ;W[ki] ;B[hg] ;W[pb] ;B[pc] ;W[md] ;B[ob] ;W[ge] ;B[kh] ;W[nc] ;B[nb] ;W[jr] ;B[ir] ;W[cj] ;B[bj] ;W[bi] ;B[dj] ;W[ch] ;B[di] ;W[dh] ;B[gf] ;W[he] ;B[ff] ;W[li] ;B[bf] ;W[bh] ;B[lh] ;W[ji] ;B[ij] ;W[ig]C[oh dear] ;B[ek] ;W[ih] ;B[jl] ;W[eg] ;B[hf] ;W[if] ;B[ed] ;W[gm] ;B[lk] ;W[ko] ;B[kp] ;W[ep] ;B[gr] ;W[ll] ;B[kl] ;W[lm] ;B[mk] ;W[nl] ;B[nk] ;W[ol] ;B[ml] ;W[kk] ;B[kj] ;W[fe] ;B[ef] ;W[mm] ;B[pm] ;W[nm] ;B[qi] ;W[pk] ;B[ok] ;W[lj] ;B[jk] ;W[pl] ;B[qm] ;W[nj] ;B[oj] ;W[rj] ;B[ri] ;W[qj] ;B[fd] ;W[gc] ;B[rn] ;W[rf] ;B[sj] ;W[sk] ;B[sh] ;W[se] ;B[rk] ;W[si] ;B[gd] ;W[hc] ;B[sj] ;W[dp] ;B[cp] ;W[si] ;B[ne] ;W[nf] ;B[sj] ;W[dm] ;B[cm] ;W[si] ;B[be] ;W[db] ;B[sj] ;W[co] ;B[cn] ;W[si] ;B[bd] ;W[bc] ;B[sj] ;W[cq] ;B[bo] ;W[si] ;B[dd] ;W[cc] ;B[sj] ;W[cr] ;B[er] ;W[si] ;B[lo] ;W[kn] ;B[sj] ;W[bp] ;B[fr] ;W[si] ;B[jh] ;W[ii] ;B[sj] ;W[co] ;B[kf] ;W[ni] ;B[mj] ;W[mi] ;B[nh] ;W[ke] ;B[cp] ;W[si] ;B[je] ;W[jf] ;B[sj] ;W[br] ;B[aq] ;W[si] ;B[pj] ;W[qk] ;B[sj] ;W[ap] ;B[cs] ;W[si] ;B[lf] ;W[me] ;B[sj] ;W[bs] ;B[ar] ;W[si] ;B[ec] ;W[eb] ;B[sj] ;W[hh] ;B[gh] ;W[si] ;B[jd] ;W[ie] ;B[sj] ;W[fg] ;B[gg] ;W[si]C[without the ko, B is leading by about 10 points actually I can't work out why B loses.
