And it’s not Gote, because once B1 makes Black safely connected and strong, the White corner is vulnerable!
Then if Black is allowed to continue with B2, W“b”, B“c”, the corner is dead! So White must defend immediately.
White could expand his corner slightly via W“c”, B“d”, W2, but although that would nominally be Sente it was nevertheless unpalatable because B“d” would then have undercut the not too strong White formation to its right.
So White instead prudently chose to live in the corner in Gote via W2.
