BQM 598

on a 13x13 board  

On a 13x13 board, White just played white+circle. ​ Assuming black+square is safe, can Black live in the upper-right?

White has 2 supporting stones to close to this diagram's upper-left, and one of them is a 4-4 stone in the upper-left corner, so Black attacking White's stones at the top of this diagram can only help to the extent that it helps Black make Black's own life in the upper-right.

(In the game, we played this sequence..)

fractic: After the game sequence black is not yet dead. You can connect using B1. If W2 then B3 and white can't cut at a due to lack of liberties.

RickyDemer: ​ ​ ​ Oh, nice. ​ (As you presumably guessed, we both missed that.)
