Post subject:  cornerphobia

you could argue that this isn't a Beginner question, but i think it is, as i am a reBeginner and it's my question.

i wish Go didn't have corners, because they make life so troublesome: there's the inside and outside and the left and right as well, making 6 things to have to think about at the same time and i find it difficult enough to chew gum whilst walking, so,..

here, it looks like white is giving black a chance to get in the corner, but how should he/she go about doing that, if at all?

if anyone can speak plain English and say it simply please do so (otherwise forever hold your peace!) - we had a bit of a discussion about it, which you can see in the sgf, but i ended up more confused than ever.

at least we agree on something (even if you didn't follow instructions) :)...

oh, wait, my apologies, you are not saying you can't at all speak plain English, but that black should keep out of the corner.

ok, fair enough, but why? too soon? biggger fish to fry? like R2? R2>D2?

I'm only a beginner, but my thought is that trying to develop the left side seems bigger for black than taking the corner. I also feel like black is thin on the bottom side, and any kind of invasion in the corner will likely harm blacks position there, for little territorial gain.

:) you don't sound like a beginner... and i see you are sdk, so a pretty advanced Beginner at least.

i'd be interested to hear your thoughts on
viewtopic.php?p=227262#p227262

but seeing as you are an advanced beginner, please wait until a ddk has had a go at it first.

I think not at all, because black is not strong enough on the outside to enter (with profit).

After the honte move of C7 and the white answer C5 other parts of the board are more interesting (P2).

In the game after the black move of E3, white should consider D5 instead of E4.

so E3 should have been at C7, then white draws back like Redmond advised A0 to do.

i didn't want that, so figured i had to jump into the corner before the door was closed completely.

But, as you say, i should have left it alone until the right time; i'm sure that's what my new heroin(e) A0* would have done.*

[ps how to make text wrap around a pic? and what the heck are "go" and "gwave"?]

after E3, D5 is better than either E4 or F3, even though it makes D6 almost look like a nose tesuji,... but it wouldn't be tesuji, because of C6? in fact, far from being a tesuji, it looks like a little dango all by itself, making it worth less than nothing to black.

so the situation after [D6..C6; E3..] is an example of an unusual situation in which reducing liberties (with D5) is stronger than increasing them (with E4 or F3), because white is well-connected and black has 1, 2, 3, 4, 5 separated stones - yecchh!

that's very instructive, thank you.

i guess that means that (a) D6 was wrong direction, and (b) C6 was a good reply to D6, even though at first glance it looks kinda clumsy - although, then again, maybe there's an even better reply to D6 than C6?

i will advise black to either give up the game or buy another copy of Iwamoto's superb Introduction 'cos he's clearly got no idea of what it's all about (sob, sob). Still, at least i was correct to say it was a Beginner's question.

PPS. P2>R2 Doh! how could i not see that? Whisky, please - make it a double.

PPPS Oh! Oh!!!

having learned nothing... Nothing! zip, zilch, zero... white gives black 4 corners AND lets him have an easy life in the middle!
