A problem from the British Go Journal issue 158. I don’t play Go any more, but I still like it. This problem is particularly pleasant. It is symmetrical, so there are only 6 possibilities. Black to play and live.
SGF visualised with GoRilla.
f then b or b’ for the first eye?
I’ll have an E please, Bob.
[Yes. Unless it is a problem designed to break that rule. But this isn’t :-) -W]
Long time no play. Hmm. I think I’ve got it.
Black F, it’s the crucial place to form two eyes. White E would threaten to connect at A, but can be countered with D. The freedom above D is crucial to black’s survival.
Playing E would have white press down at A and A’, which need to be countered by B and B’, respectively; then A takes F and Black dies.
[Yes. And in a certain meta-way, its obvious: no other play is sufficiently counter-intuitive to be an interesting answer. I realised it eventually when I found, in all the other sequences, that white kept playing at “f” -W]
OT – other fun.
With AMSR down, what is now your favourite map/graph?
[Ah, is that it? I’d noticed that IJIS wasn’t updated, but hadn’t been paying attention to why. I’ll need to think about that -W]
There is quite a collection at
is probably most similar to IJIS/JAXA one.
There is a pool for the maximum at
with my brief, but probably useless, pointers.
Hey I got that straight away, and I haven’t played in 20 years (and wasn’t any good then). If *white* plays f, then black can’t make two eyes. What do I win?
AMSR2 is due for launch in a few days, but aneone got any ideas how long before information becomes available? Dr Spencer said they wanted a year of overlap between AMSR-E and AMSR2 so I am doubting calibration phase will be quick.
News of end of AMSR-E was in update to
The graph page does say “Sea-ice data update stops for a while due to the suspension of AMSR-E observation.” and graph even had an AMSR-E heading.
[Interesting. Hopefully something obvious will be in place before the Spring for the bets. Either that, or the answer becomes obvious -W]
Do not guess that experienced essay writing company will work for free! supreme quality cannot be very cheap! Never strive to buy custom written essays for low costs, because such customized papers could be of poor quality.
