Chitetsu left the top right corner and the bottom left corner as miai and played a pincer in the top left corner. That's a reasonable strategy, except that, starting with AlphaGo, today's top bots do not like the early pincer, as a rule. Elf docks this pincer 16½% to par. Dosaku then enclosed the top right corner, another reasonable choice, which Elf docks 13% to par.
Elf, along with Harleqin, prefers the press at
a in the bottom right instead.

Black now sacrifices the
stones in the corner. For
Elf has a slight preference for
a, but the solid connection is sound.
The press from the 5-3 against the 3-4 is a real workhorse.
