# From L+1 group / discussion

Black lives 2

Erock: Can Black also live by playing the 1-2 point?

Black gives white an extra ko threat

Answer to Erock: Jared Beck: In "Black lives 1" black lives, and white has 3 ko threats for a later time. In "Black lives 2" black also lives, but white has 4 ko threats.

Or Black loses a couple points

Jared Beck: If Black chooses to give up a few points, he doesn't have to suffer the burden of a fourth ko threat.

Jared Beck: Please double-check this, I just looked at it briefly.

1-2 point

Chris Hayashida: The problem with the 1-2 point is descending on both sides (marked stones) threatens to kill the group. This isn't the case if was played correctly at the 2-2 point. Black cannot play at a for his second eye since it is self-atari.

White kills
