I haven't a clue. The translation given, gazing from a distance, does not specify anything about being higher.

I guess most low(er) moves would be considered kakari (approach) or uchikomi (invasion) or wariuchi (splitting move), but then again many high moves might also be called kakari or keshi (reduction) or yosumi (probe).

But a move can fit multiple terms at the same time, so perhaps a move can be, say, both wariuchi and nozomi at the same time. Someone familiar with the Japanese usage would have to chime in on that to be sure.

As is, the page is simply wrong.

According to multiple Wikipedia pages, the word nozomi in Japanese means "hope" or "wish" and is also a name. So far, I'm taking it as a loose threat/approach. Based on limited information!
