As already indicated, in pro play Black has made a few different responses. Black played this counter-pincer as
![black 7 :b7:](./images/smilies/b7.gif)
in GoGoD 1776-06-00a, Wakayama Ritcho (W) vs. Suzuki Gennojo, and 1782-03-11, Yasui Senchi Senkaku (W) vs. Kono Mototora. In both games White responded with the kick in the corner,
![white 8 :w8:](./images/smilies/w8.gif)
. And then
![black 9 :b9:](./images/smilies/b9.gif)
was the combination two space extension cum three space pincer, also in both games. But Elf prefers the stand at
a for

This variation comes from the Elf commentary for the Wakayama-Suzuki game, which gave it more rollouts, 54.5k, than the Yasui-Kono game.
After
![black 9 :b9:](./images/smilies/b9.gif)
,
![white 10 :w10:](./images/smilies/w10.gif)
secured a 3d line base for White in the corner. Then
![black 11 :b11:](./images/smilies/b11.gif)
occupied the last open corner.
![white 12 :w12:](./images/smilies/w12.gif)
turned to the press in the top right corner, and then
![white 16 :w16:](./images/smilies/w16.gif)
broke the sector line in the top left. Then
![black 17 :b17:](./images/smilies/b17.gif)
made a base on the top side, countering the influence of the White wall in the top right.

made a thin, three space extension towards the bottom left corner, which
![black 19 :b19:](./images/smilies/b19.gif)
enclosed with a keima.
![white 19 :w19:](./images/smilies/w19.gif)
played the 5th line keima, attacking the

attacked the thin White wall in the top right, taking away its potential base on the 3d line.

This variation comes from the Yasui-Kono game, which gives it more rollouts, 25.9k, than any other game in the Elf GoGoD commentary that has the same position after
![white 6 :w6:](./images/smilies/w6.gif)
.
![black 7 :b7:](./images/smilies/b7.gif)
pressed against the top left corner and then
![black 11 :b11:](./images/smilies/b11.gif)
occupied the bottom right corner. Note that Black occupies the bottom right corner in both mainline variations.
Next,
![white 12 :w12:](./images/smilies/w12.gif)
played the press in the top right corner.
![black 13 :b13:](./images/smilies/b13.gif)
replied with the kick, and
![black 15 :b15:](./images/smilies/b15.gif)
played the slide on the right side without further strengthening White.

invades the bottom right corner, with the following joseki.
![white 26 :w26:](./images/smilies/w26.gif)
does not show up because it got fewer than 1500 rollouts, if any, but the crawl to
a is the expected play. As always, long variations should be taken with a grain of salt.
The main difference between the press and the counter-pincer appears to be the strength of Black in the top left corner with the press, while with the counter-pincer Black's two stones in the top left are more vulnerable As indicated, the occupation of the bottom right corner does not appear to be much of a factor.
