BQM 442
A problem from two different 7x7 Go investigations.
In 7x7 Go b is mentioned as best move.
While on an
SGF about the same problem a is given as best move.
Please high ranking Go players tell me (12 kyu) what is best.
Dieter: I am no expert, but here's what I see. Black's throw in forces an extra move inside White's territory later.
If Black simply descends, White gains a point with
. So I'm inclined to vote for the throw-in.

Hi Dieter Thanks for your reply.
according to the
Tromp sgf the following is best
your remark about the neutral points is valid white needs to add a stone inside his territory so loses a point under territory rules
(and this way the problem becomes an wholeboard endgame problem
lightvector: Edit from years later in the future! (2021)
KataGo suggests that the throw-in may be actually completely unplayable for black, because white has this placement to cause trouble next. The immediate threat is the cut at "a", Black must defend it somehow.
