Black to live inside or escape from the heart

Try solving on the interactive screen here.

If you are white, do you choose to let black live inside your heart or let black escape from your heart?

Not a tsumego but an endgame problem.
What’s the value of this triangle endgame move?

  • A: 5 points
  • B: 5.333 points
  • C: 5.5 points
  • D: 6 points

I just chose the one with a third in it because it looks like it involves ko, lol

btw, is this miai or deiri?

I suppose it’s deiri… If Black plays first then Black gets 5 points in the zone A1-B1-C1-D1-C2. If White B2 is followed by Black C2 and White A1 then

  • If Black plays C1 next, then Black has 0 point (1 point for D1 but White has captured 1 stone).
  • If White plays next, then Black has 0 or -1 point depending on whether White wins the ko.

I conclude that after White B2, Black has between 0 and -0.5 point. So the deiri value of B2 is between 5 and 5.5 point, and I vote 5.333.

Anyway, I’ve never taken the time to study endgame seriously so I’m not able to make the precise calculation.

Black to live

C9 should be it, I think

C9 B3?

B3 how? if you mean A3 then black has 3 liberties while white only 2

Sorry yeah A3. White can’t win in liberty race but white can remove your eye.

You can try it out here.

Oh, I see now. thanks. The combination of A5 & B6 to steal the eye was such a blind spot for me.

Attempt

B4 B5 A5 B3 B6

Response

B3 play at C6 instead

Then perhaps

A6 C6 B3 A5 B5 B4 A4 and white can’t atari because of lack of liberties.
