A Life and Death Problem


A life and death problem from one of my games in the game White lived (I had black)

But is that due to my bad play or could it be killed?

Black Plays First


fractic: Black can easily kill with B1. W2 is actually dying in gote because the circle are miai.

ThorAvaTahr: Black's strategy here (or in any other life and death problem) is to first reduce the space where white can make eyes and later (if necessary) do a placement on the vital point of the group.

B3 elsewhere  

ThorAvaTahr: White cannot make two eyes here

B3 elsewhere  

ThorAvaTahr: Same here: white cannot make two eyes

White Plays First

Dead afterall  

willemien But now White having the first move

fractic: I just glanced the first time because I thought you were asking if Black could kill. But now that I've taken a longer look it looks like White was already dead.

Variation with similar result.
