C[Semiai Class 1. Same eye status. Size eye = 7, Very important how to fill the eye if it is unsettled. This test is not about unsettled 7 space eyes but about how to win those semiais regardless the eye.
NW: Black to play (E19|F18|F17), playing inside the eye or in the shared libs also works but not recommendable, and win. White to play T16(F12|F11|F10|F9|E8|D8) and seki, Playing inside the eye also works but not recommendable.
SW: Black plays E1 and wins. White plays B2 and seki.
SE: Black plays and seki. White plays and seki. Seki unconditionally. Both to play pass.
NE: The one who plays first wins. Black to play (N17|L16) though in this case N18 would work it SHOULDNT play there. White to play (Q17|R16) though T18 would work it is NOT a good idea.
