At position Q16,R14,O16,R17,R16,S16,S15, @S_Alexander started the conversation:

Would white ever play S18 to slide further along the top?

( FYI @mark5000 )

Josekipedia cites Kim Yeonghwan for the proposition that the move “has basically disappeared in recent pro games” and is situational.

I’m thinking S18 trick to jump further could be useful on 9x9 board when the opponent has two 4-4s.

On a 9x9 board, a 2-5 invasion of two 4-4s is almost always preferable to 3-3. So the position would rarely arise.
