C[To view the comments and the game score properly, set your viewer \
program to SHOW NEXT MOVE as the character "a", which is SGF \
style viewing. If your viewer is set right, then the character \
"a" now shows on coordinate R16, which is black's first move.
In the text, w=white and b=black or b=another variation, depending \
on the context.

mitdahand (black) vs caibobo on the Game Zone server

All comments are by Yang Yilun, 7-dan professional, unless otherwise \
noted from Kim Dae Yol, amateur 6d, who I showed the game to \
separately.]

PL[B];B[qd];W[dp];B[pq];W[dc];B[oc];W[jd]
C[a is the biggest move.

(Mr. Kim said he believes that w6 is doable. He prefers either \
b or c in this type of position for black.)]

(;B[ce]
C[w has a strange position on the top.]
;W[cg]
C[a isn't proper.  b is the correct move in this case. see variation.]

(;B[ed]
C[w has to push out at b]

(;W[ec];B[fd];W[fc];B[gd];W[gc];B[hd];W[ic]
C[This result is ok for b. A is the best pincer.]
;B[cj];W[eg]
C[a is an ideal point.

(Mr. Kim says b must come out now at b.)]

(;B[cn]
C[My question:
Instead of a, what if white did the moves shown with b etc. How \
can black handle it? (See variation for Mr. Yang's answer.)]

(;W[fq]
C[a is a solid defense; but, it is a little too soon. b has to \
move out at b first. see variation.]

(;B[dl];W[bp]
C[a is the best move to get out.]
;B[hg];W[ff]
C[a is necessary.]
;B[dd];W[hf];B[if];W[gg]
C[a is ok, but b could be faster.]

(;B[ig];W[ie]
C[b is the correct sequence.]

(;B[hc]
C[now w might connect at b.]

(;W[jc];B[he];W[gf]
C[a is an important point. b is good timing.]

(;B[cc];W[cb]
C[a is the normal tesuji. b is the best move in this case. see \
variation.]

(;B[bb];W[bc];B[cd];W[da];B[ba];W[hb]
C[Now w is not too bad.]
;B[bf];W[bg]
C[Yes, a is a free forcing move.

(Mr. Kim says that b is lighter for black.)]

(;B[je];W[id]
C[a is not that important when w's top side group was strong enough. \
b is the best move.

(Mr. Kim says a is heavy.)]

(;B[ke];W[lc]
C[a is great.

(Mr. Kim says play b right now.)]

(;B[gi];W[cf]
C[b is better than a.]

(;B[ad];W[be]
C[b should extend to b.

(Mr. Kim says same thing of course.)]

(;B[ae];W[af];B[bd];W[ej]
C[a is just nice.]
;B[fk];W[gh];B[hi];W[hh];B[ih]
;W[ek];B[el];W[fj];B[gk];W[gj];B[hj];W[fi]
C[a is the best defense.

Mr. Kim says w may die if b plays b.)
My Question to Mr. Yang later is: Can black kill white with a \
play at b?

I don't think so... (see variation)]

(;B[hk]
C[This result is good enough for b.]
;W[di]
C[a is an ideal point, but b is the biggest move. see variation.]

(;B[md];W[qj]
C[Now the marked stone is not that useful.
a is wrong. c is much more valuable than a. See variation. 

(Mr. Kim says a is a direction mistake. He recommends b.)

My Question to Mr. Yang later: I know you said c was the proper \
move. I am wondering if b is almost the same as c, and, therefore, \
is b better than a?

b is better than a, but c is the best - we should have to develop \
wider open area, and to make thickness useful.]
TR[md]

(;B[oj];W[qg]
C[a is ok. b is more important. see variation.

Mr. Kim says once you played the marked stone, you have to follow-up \
with c.]
TR[oj]

(;B[gp];W[gq];B[ip]
C[a is really big.]
;W[po]
C[a is the best move.]
;B[oo];W[on];B[no];W[pp];B[oq]
;W[pl]
C[Mr. Kim says a is big but inconsistent. He says b should stick \
with his center plan and follow-up with b. See his variation.]

(;B[qq];W[nn]
C[a is a big move. b has to hane at b first. see variation.]

(;B[hq]
C[now w might extend at b.]

(;W[mo]
C[a is a severe cut.]
;B[mn];W[mq];B[nq];W[jq];B[ir];W[lo];B[mm];W[mr]
(;B[jn];W[rp]
C[Now w is going to attack b's corner.]
;B[qp]
C[Now w might defend at b. See variation.]

(;W[qo];B[rq]
C[Now b is safe.]
;W[nr];B[or];W[jr]
C[a is a really big move.]

C[a is a nice defense.]
;B[km];W[nl]
C[a is a nice move.]
;B[mk];W[oi];B[ni];W[oh];B[nh];W[ng]
C[a is too much. b is the proper move.]

(;B[og];W[of];B[pj];W[qi]
C[This is nothing for black.]
;B[mg];W[nf];B[mf];W[re];B[rd]
;W[nb]
C[Must defend at b because the corner is more valuable than the \
right side.]

(;B[rf]
C[W has to push at b.]

(;W[qe];B[se];W[qf];B[ob];W[nc];B[nd];W[pd];B[pc];W[od]
C[a is the best defense.]

C[b is necessary.]

(;B[gr];W[gn];B[go];W[fn]
C[a is ok. b is better. see variation.]

C[a is not meaningful. b should just play at b.]
