I played black in this game. It was a close game, so not seeing this move may have lost it for me. It was only looking over the game afterwards that I noticed this point.

We don't know who we are; we don't know where we are.
Each of us woke up one moment and here we were in the darkness.
We're nameless things with no memory; no knowledge of what went before,
No understanding of what is now, no knowledge of what will be.

Either way, W+10.5 ... can B do better?

Yup, you all found it :) . @ EdLee: it was a no-komi (handicap) game, and I had two more prisoners, so I think the actual difference would be something more like W+2.5 if I had found this tesuji. Not quite enough, I guess. In the game it sat for a while before white defended, I'm not sure if white didn't see it either, or was just counting on me not finding it.
