I’m still a DDK at heart (last rank adjustment promoted me to SDK) so here’s my try
I think there’s 4 different moves to consider the order and sente or gote, ABCD:
I think that A must be the first move for black, it’s sente because the follow up is so big (destroy whites upper left territory) I didn’t count what happens if white ignores this
After that I just tried to count the remaining moves, to compare the score.
First, B if black plays first:
if white plays first:
Assuming these basic variations (assuming opponent responds and doesn’t ignore) it seems like +2 points territory +1 point for capture for whoever goes first. Does this mean that it’s effectively a 6 point swing? This is where I start to get confused… Also confused about what happens if the opponent doesn’t respond here, it seems like there’s another 1 point for reduction
Okay moving on to C, if white plays first:
This looks like it’s worth +2 points territory +2 points captures for white
But if black plays first, it’s just +0 points, just preventing white from getting +4
Last one, D if black plays first:
So +2 points for black, If white goes first I think it’s basically preventing black from getting those points:
Black could also turn at C1 in gote to reduce 1 white point…
Okay here’s my summary of the value between BCD:
- B - 6 points (1 extra for reduction?)
- C - 4 points
- D - 2 points (1 extra for reduction?)
But what gets really confusing to me is which of these is really sente or gote, because it seems like the best play is actually to ignore sometimes (in other words is not actually sente)?
Here was my final sequence:
1-4 Black starts here because it’s so big, and ends with sente
5 Black plays here for +3 points
6 White ignores because this is worth +4 and follow up to Black 5 is only 1??
7 Black does not follow up because this is worth +2??
8-9 White can play here in sente, and Black responds to keep the points??
10 White finishes here
I’m very much not confident in this evaluation or ordering, so won’t bother counting final score yet…
Just my humble opinion, the other problems are not that easy I think, for new ranks DDK… at least this new ranks 8k has a hard time this is the only one I have a bit of confidence in:
Fun topic though
