mitdahand:
Hello Mr. Yang. Please comment on this tournament game I lost \
to Mr. Moon Cha 6d by 1/2 point. I'm the White stones. Thank \
you.]

C[mitdahand:
Anyway to take advantage of the unusual black pattern? 

Yang:
No chance yet. Your move is right -- just take the empty corner \
first.]
;W[pc];B[op]
C[a is big.]
;W[cd];B[ce]
C[a is the only move.]
;W[be]

C[mitdahand:
I had the marked stone in mind when I played next at a. Is it \
okay? 

Yang:
You are right. a is the proper move in this case.]

C[a is the proper extension.]
;W[ci];B[ic]
C[This is a good result for white. a is too soon. b is bigger.]

C[Now black can play at b.]

(;B[jq]
C[a is the biggest move.]
;W[dq];B[fq]
C[White has to get out and b is better -- attach to a stronger \
stone...]

(;W[do];B[dn];W[eo];B[cp];W[eq];B[cq]
C[a is the proper defense.]
;W[gq]
C[But white isn't comfortable.]
;B[qe]
C[mitdahand:
How is b instead of a?

Yang:
a is the best pincer. b is more urgent...]

C[mitdahand:
I hate this push at a, but ...

Yang:
a isn't necessary. White has to just cut at b...]

... I was protecting again Black  at b.

I know.]

C[a is the proper answer.]
;W[ch];B[bg];W[cg];B[bi];W[cj];B[bj];W[cf]
;B[pe];W[nd];B[ne]
C[b is the correct answer.]

(;W[me];B[nf]
C[ Now white needs another move for defense.]
;W[md]
C[Both marked stones are a bad exchange for white.]
TR[me][nf]
;B[pk]
C[White isn't easy to capture black four stones. So, b is a better \
way to get out..]

(;W[nh];B[mf]
C[a is a good move.]
;W[lf];B[mh];W[ni];B[lg]
C[a is a severe move.]
;W[ol];B[pp]
C[b is more useful.]

(;W[qo];B[qq];W[qr];B[rq];W[rr];B[nr]
C[b is the correct move -- good for eye shape and endgame.]

(;W[or];B[os];W[pr];B[kf]
C[a is a thick move.]

C[mitdahand:
Can White do better than a? 

Yang:
No, a is necessary.]
;W[nb]
;B[mc];W[nc];B[bb];W[ab];B[cb]
C[a is important forcing move.]
;W[dk];B[dl]
C[a is too soon. White has to just extend at b.]

(;W[cl];B[bk];W[ek];B[eg]
C[mitdahand:
I guess White must not neglect b.

Yang:
Both a and b are solid, but slow. c is the best defense...]

(;W[el];B[ei]
C[a is a good move.]
;W[fi];B[fh];W[fj];B[kc]
C[mitdahand:
How is white a?

a is doable. b is the proper reduction...]

C[White got forcing moves outside, not bad at all.]

C[a is ok. White can play at b...]

C[a is a good forcing move.]

C[a is a nice move.]
;W[io];B[jo];W[ke]
;B[je]
C[a is the proper move.]
;W[jn];B[ip]
C[Yes, a is really important.]
;W[ji];B[kn]
C[a is little slow. b is better...]

C[b is the correct answer.]

C[b is better.]

(;W[rc];B[kk]
C[a is big. b is even better.]

(;W[rh];B[jj]
C[mitdahand:
Should white just play b?

b isn't that big.]

C[a is really big.]

C[a is a big move. White has to cut at b first...]

(;W[sh];B[hi];W[gi];B[hj]
C[a is too bad. White might play at b...]

C[b is bigger.]

C[Yes.]
;W[cr];B[br];W[mm];B[no]
C[a is biggest.]

C[mitdahand:
This next move at a was actually played earlier, when black had \
to answer at K13. The game record was slightly out of order.]
;W[kh];B[jg]
C[mitdahand:
I guess White a is a mistake that finally lost the game.

Yang:
 a is too deep. b is the biggest move...]
