If Black turns at 1, White can't stop him from getting two eyes..

Erratum: White can make a seki by playing 2, the sequence to 4 leads to seki.

Grauniad: Huh? Doesn't B5 at a, capturing 2 stones, give Black two eyes? What am I missing?

Niklaus: Throwing in at W6 (or below, of course) prevents black from capturing the two stones in the corner.

Dieter: This gives seki. Seki is all right. But I agree that the comments often fall short.

Skelley Ah... seki is alright, but it is not two eyes as promised, is it?

victim This Black 3 is actually worse than Black 3 at 4, since Black doesn't get any prisoners.

Grauniad: But why would Black at B3 choose an inferior seki?

victim: I was confused - too much work on my time machine tends to disturb my sense of causality :) I corrected my text.
