I'm an EGF low 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'm involved in the English and German Go community in various way, most prominently I've created a platform for bad Go jokes.

comment Corner variation which is not in Josekipedia
@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?

comment Corner variation which is not in Josekipedia
@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 :)

comment Corner variation which is not in Josekipedia
@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)

comment Corner variation which is not in Josekipedia
@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.

@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.

comment How do I properly place handicap stones?
What is the order of the moves 5-9? Afaik it is left, right, top, bottom, center, but why play 3 on the lower side and 7 on the upper side, isn't it inconsistent? (I wonder about the order of symmetric moves, too, even though I'm sure nobody would notice in a real game.)

comment Deviation of 3-3 invasion - how to live/kill?
We do not yet have a good way to search for specific positions or joseki sadly ;( Btw, I see this is your first question here (and already really well formatted!), so welcome on Board and Card Games :)

comment Does anyone else use The Little Girl in Werewolf?
How does the "spotting" part work? Can't the wolves just point at a different person each turn, no matter if they were peeking, until they eventually find the Little Girl and have her killed? Or is pointing out the peeker possible only once?

Not sure if the second diagram I added actually is what you meant. Looks a litte funny to me.

comment Komoku-Oogeima joseki order variation
The shoulder hit seems to lead to pretty complicated fighting and several semeai possibilities on the edge. Just as you said, really difficult to judge. I guess if black were to just push and connect by clamp it would be too submissive.

comment What is the formula of rank difference to handicap stones?
@KarlKnechtel Certainly. Ranks do not really work for beginners. They become a reasonable approximation starting around 10 or 15 kyu I guess. To create meaningful statistics, you'd have to refer to dan level games so the noise in the samples is lower.

comment Is giving resources away for free allowed?
My mistake! Thanks for pointing it out, it's been a while since I read the rulebook and I remembered it wrongly. Very interesting.

comment What is the meaning of 'karai' and how is it applied?
Yeah, that's true, my mistake, I forgot about that. That is something actually new, and very useful.
