>Comment[Yang: is it the biggest point? Some other big points, I think, are: Q18 \(slow?\), Q10/R10, C14\(I don't quite like it since white will get more valuable top with F16 while b get less valuable left side.\) I am not sure if my friend's feeling is correct. This kind of questions \(where is the biggest and where is the most urgent place\) give me headache.
>OBN: Top seems W big area and most potential.At the bottom I believe I might prefer Bl3 to Bm3. I like the relationship to a possible Bj2. Bc14 on the left seems not too valuable because of relationship to bottom-left, maybe Bc10 instead
>but it feels a bit slow somehow.
>OBN: Outside the moves provided, maybe Bo15 might be interesting, then if W protects the o17 stone at top, Bl4 would start to shape a B moyo. I think I like
>this best because I believe Bo15 is sente and Bl4 then develops B while
>constricting W's development at the bottom ... making it look just overconcentrated. The right side may be too wide, maybe W will invade instead of answering Bl4]

>Comment[Yang: it seems to me it is the right direction since the left side is wider than the upper side. That is, I think this move is better than F17. However, I don't quite agree on white's next move. see var.B for what is in my mind about white's next move.]

>Comment[Yang: now it is a tough decision how to reduce white's moyo. J15 looks normal to me. But before playing J15, should black play C18 first? However, black might as well limit white's moyo from the lower side with K5. Furthermore, with K5 black can strenthen his moyo. \(cf. white M5 if black not K5\) So is the lower side more important? Big point, urgent place, order, timing,... I am totally lost.:-\) 
>\(So I joked my friend: why don't you just throw a dice and make a choice? But he didn't. This move took him 5 more min. Time is running out...\)]
