Sunday Problem #61

Published 1 Aug 2021 by antti (last edited 8 Aug 2021)

This is a classic corner problem.

Black to play.

Solution (1)
The diagonal move of black 1 is a tesuji in this shape. If White resists with 2, Black cuts the white shape with 3–6 and finally wins a local capturing race with 7.
Solution (2)
White’s connection of 2 here is an alternate resistance, but it fails to Black’s 3–7. In both solution diagrams, black 1 is a key point for the local capturing race.
