I'm a 27 year old EGF 1 dan, playing Go since late 2006. I was active in the community at Sensei's and the former SE-1.0 site shidogo.com, now switched my attention to BCG.SE

I've created a platform for bad Go jokes.

This is very true, I never understood how handicap and betting can be used together in the same game.

comment Corner variation which is not in Josekipedia
@goldPseudo Absolutely, I completely missed out on thinking of a different black 5 and only considered black 7, leading me to miss shujaa's excellent move. In diagram 7, it is intentional though, it's a different situation, arrived at from the usual joseki, to highlight why simply always reverting to joseki would be too easy on white.

I think this question greatly showed up the potential of collaborative research possible on Board and Card Games. Each answer highlights a few important aspects, and taking all of them into account, we get a very decent solution to the problem. :)

comment Corner variation which is not in Josekipedia
Regarding your first diagram with the Chinese fuseki: I would be reluctant to say that this is necessarily bad for white. Rather, I would consider the pincer at R12 almost a mistake, because in your sequence white gets an easy life in the corner. The right side is not bad for black, but it looks a bit easy to make overconcentrated (I'd try shoulder hit at Q8). Instead of the pincer, I would rather try black 8 or black 6, trying to enlarge the corner while keeping the white stone from getting an easy base. However, I guess it's playable and I could not confidently call it bad for either player.

@shujaa (2) Oh. Oooh... excellent idea. Haha, I tend to miss obvious shapes, as you can see :) No, please keep your answer, there is no need to include everything in one answer.

@shujaa (1) I don't think so, but I'm not completely sure. Black has moves like R13, Q14 or S14 to exploit the respective weaknesses of either shape. But black is not exactly strong himself in this area since white can try to take sente after black 3, possibly preventing black's extension on top.

@StéphaneGimenez: I edited the post and tried to implement your ideas. Phew, got quite long.

@StéphaneGimenez: About the second diagram in the first section: No, I have never seen this variation at all, even less in a book. It was just an idea that came to my mind in case black really really wants the top side all of sudden. I agree that it's better for white in general.

@StéphaneGimenez: About O17, P16: I misread P16 for P17, sorry. This variation didn't come to my mind at all yet, haha. Without the ladder I suppose black has to hane from the outside, white connects, black connects, white cuts at O15. I guess it's an even fight?

@StéphaneGimenez: Regarding black's bend being gote: Yeah, I'm not sure, White ended in sente twice so I agree that it may be slow for black to capture the single stone. My idea was that the second push of white is sente, too, and avoids giving black this incredibly strong shape (enabling slight aji of a cut at P16. Maybe it's a matter of style, I really love aji :)

@StéphaneGimenez: About P16 reverting to the cut, I don't think it will really revert because there is one additional push. This makes it considerably harder to attack the 5 (instead of 4) black outside stones. I guess it would lead to a fight that is not bad for black (cut O16, nobi N17, move the cutting stone out O15, hane Q14)

@StéphaneGimenez: If crawling at O18, I would probably crawl a second time to avoid black's bend. Either way is relatively painful for white as black gets very, very strong on the outside, far more than by the usual joseki, while being enclosed too. I cannot tewari-prove this but my understanding is that this is bad for white unless sente is super important (but in that case white has different ways to play that do not make black as thick).

@shujaa: Yes, I agree, black's A may well be a far bigger mistake than white's hane. I misjudged it initially.

comment Corner variation which is not in Josekipedia
@shujaa: As far as I can tell, the clamp does in fact work, even though a little different from the usual situation. That's why this can't really be used as refutation, which makes the deviation superior to regular joseki, which is impossible, of course.

comment Corner variation which is not in Josekipedia
After consulting a few sources, it seems what I just wrote is mostly wrong... now I'm really confused, because white's deviation is not supposed to be superior to joseki regardless of the ladder ò.o

comment Corner variation which is not in Josekipedia
I'm pretty sure black should hane regardless because the clamp doesn't work. I remember this shape from a misplayed punishment of a joseki deviation which will backfire badly. If black had to play the nobi instead of the hane, it would be too good for white because black lost the possibility of playined S17 after Q17, which is a different joseki.

comment How do I properly place handicap stones?
@KarlKnechtel But shouldn't 3 be at 4 (far side) in that case?

comment How do I properly place handicap stones?
@KarlKnechtel: Why is 7 on the far side? The reasoning of 3 would indicate a placement on the near side to make it easy for w to place her first stone.

comment Is it allowed for the next player to take the next tile while the current player hasn't finished his move yet?
As far as I know this is merely a "common bad habit". I vaguely recall at least the European ruleset to state that this practice is not allowed in tournament play - it does give the hasty player an unfair advantage in cases of tile calls after all.

comment Second line invasion of two-space extension
Don't have any books available as reference right now sadly, so this is just from the top of my head - let me know if I made a mistake or if there's anything that should be further explained.
