C[Semiai Class 1. Same eye status. Size eye = 7, Very important how to fill the eye if it is unsettled. This test is about unsettled 7 and how to fill the eye.

NW: Black wins if he unsettles the nakade. White wins if he achieves seki. Black to play
(C18|B17|D17) but NOT (B18|D16). White achieves seki in (C1|B17|D17) but NOT (B18|D16).

SW: Black is alive in seki. White has only one eye and cant make seki. So Black wins the semiai unconditionally. Both to play pass.
