Q18 for a kill?
So you think itâs unsettled â White plays and it dies, Black plays and it lives?
Bit hard to read but a lot of aji on the upper side around H17 and L17 (or M18)
Bit hard to read but a lot of aji
Of course, thatâs why I posted it!
I bet it can live, donât ask me how.
Even if Black plays s18 White can still play q18 
Thereâs supposed to be some ladder variations and things.
I was supposed to have studied this before and thereâs a âstrong resistanceâ which I think was meant to depend on ladders
eg this ladder
The reason you donât want to connect against the peep is of course
Thatâs the quick analysis.
The deep analysis is I donât know, and you nearly need to take into account every stone in the upper right corner. Black can try attaching at q14 first, or as groin said try to use L17 to get some other forcing moves.
There could be like 20 move sequences to live or make a ko or something but itâs way beyond my tsumego brain.

Would you rather play a or b as Black, for (3)?
I suspect that theyâre equally good in real terms, but I feel that a is more my style, at least right now.
b probably has the slightly higher WR, but I doubt as much as even half a point estimation.
Or would you rather play away, eg. to the bottom side?
I find that in older games, up to around fifty or sixty years ago, a and b often combine to make a four-stone structure with the komoku anyway; so this is almost an issue of move order.
I would recommend B. It encloses the corner tightly and strengthens Blacks right-side potential.
A seems to try and grow the potential in a big fashion. But so big that an invasion seems too easy for white, in my opinion.

Aaaaaaaa
B prepares to fight. 2 white groups if w decide s to come on the right side
A is too like a compromise, and compromise donât work well. If I were to put pressure on w upper side I would at least play a Keima.

(This isnât my game, itâs a 6k-ish matchup.)
White a was the game move.
I thought that felt a bit rushed, so I suggested preparing first with c.
Then I had the idea of b, playing for the centre.
When I was making the diagram, I had the thought that b is a bit committal and that it might be positionally safer to play something on the left side, like d.
Black move, right?
d, b is small and b is weird too, wouldnât it be F5 instead.
I definitely pick c
No, White to play.
I resign.
Really? I donât think White is worse.
I choose b then as white

I think the shape point might actually be H5.
Thatâs what was played in the pro game LiuâFujisawa '92, without any play having happened on the top side; and Black just connected underneath with a kosumi.
thatâs good to know. and i am sure b is the shape too, cause i read it somewhere
Both look playable (B and H5)
The R12 invasion seems attractive to me
