I remember being surprised by this when it was first played against me, but it _does_ work.  \:-)

(In fact, so does _every_ Black move farther into this corner.)

Peter\: Yes. This move is not the best from the point of view of efficiency, unless White recognizes that it captures the entire corner and refrains from forcing Black to prove it \:) I played it just because I was bored of choosing between g10, g11, and g10 (which are equivalent not just in the capture-sense, but also w.r.t. efficiency).]

(;W[b9]C[Peter\: I think this move is probably a mistake, because Black can reconnect in a way that makes f7 forcing. See the next variation for how the game might have gone without this move.]
 ;B[f9]C[Peter\: This works, but d10 would have accomplished the same thing more simply.]
