Sunday Problem #81

Published 19 Dec 2021 by antti (last edited 15 Feb 2022)

This is an original problem inspired by a training game.

Black to play.

Solution (1)
The unconventional first-line jump of black 1 is correct. White is unable to draw out his stone with 2 and on; up to 7, White is captured in an oi-otoshi.
Solution (2)
White’s resistance with 2–4 is arguably more difficult to refute. Here, Black unleashes a second first-line jump with 5, and then the best White can do is turn the shape into a seki.
