Quick top of the head comment or two:
W266: "Oh. No, white, I checked this, you got nothing here."
B267: "See? Two eyes."
OMG, tsumego!
W254: "Double ko? But doesn't work if the group is dead, right?"
Right you are! Tsumego knowledge.
B255: "I take."
Huh? You just said it doesn't work.
Fill one of the real kos.
B251: Correct. At this point there are 3 ⅓ pt. kos on the board, with White to take. Each is worth on average ⅓ pt. of territory for White. ⅓ + ⅓ + ⅓ = 1. They all add up to 1 pt. of territory for White,
with no ko fight. White captures one Black stone. (Small tidbit of endgame knowledge.
) For instance, Black fill, White take, Black fill, White fill. Or, White take, Black fill, White fill, Black fill. All same same.
