Xuanxuan Qijing Problem 59: Black to play and kill
玄玄棋经 · Problem 59 of 347 · First-line moves on both sides
Black's and White's stones are cut into each other. Push in from the outside first, and then look to the first line.
How to solve it
Black's stones and White's are cut into each other in the corner. Black starts by pushing in at B17, and White blocks at A16.
Black then plays D19 on the first line. If White answers at B18, Black's B19 settles it.
If White plays C19 instead, Black plays A15. White can capture two stones with E19, Black plays D18, and after White's capture at D19, Black's A17 finishes the job: White's stones are dead.
Main line
- 1. Black B17
- 2. White A16
- 3. Black D19
- 4. White B18
- 5. Black B19
