is sente (19.2 > 7.9). So is

is also sente but what surprised me is that is "even more" sente than (19.8 > 7.5). Intuitively allowing Black to cut through the keima with a solidly connected triangle is worse than allowing atari to one stone.
cools down the position but remains ambiguous: not only is the local temperature (12.9) only slightly bigger than the ambient (12.7), also KataGo wants to play elsewhere now, against the temperature argument. Indeed, an analysis that includes passing doesn't necessarily agree with what's the best move. It might mean that my version of temperature used here is not well defined.
There are other moves available for
, most notably A which leads to the small avalanche. This variation keeps the area "hot" for a while and can even be considered to turn into a "whole board joseki"It remains interesting that an increase of local temperature seems to always induce a decrease of the ambient temperature. In the words of the definition used: a high value of a local move decreases the value of the biggest move elsewhere. This is somewhat intuitive but not trivial. A priori one might expect that ambient temperature remains relatively stable and only local temperature goes up or down considerably. But that is not the case. Allowing an early atari in a corner makes the position in that corner lopsided, so that the relative value of the other corners decreases.
A robust estimator found 13.33 and if we are only interested in small handicaps then 13.2 was the average for the first 3 handicap stones.
