Myoshu (myoushu, 妙手), Japanese for "extraordinary", "excellent", "magnificent" move. A move surprising and startling in its insight. Harboring multiple aims in miraculous fashion. Cf. tesuji, a skillful move in a merely local context.
Chinese pinyin equivalent is "Miao4 Shou3".
Tamsin: It'd be really nice if somebody could please provide some examples. Off the top of my head, there's the Ear Reddening Move and move 160 of Go Seigen-Honinbo Shusai.
Myoshu Examples: For examples see (miàoshǒu resp. miao4 shou3) Miao Shou,
I only got later the idea that someone already might have created an entry under the Japanese term. (Tderz)
