Here's my 3k guess:
What happens if = tenuki? Well, Black can certainly play at b, and white can tenuki again. But compare this with the following diagram:
This seems slightly better than the result above... although I can't give an exact number in miai counting terms (Bill Spight, are you there? ;-)
If is played elsewhere, white can play at for an even bigger reduction.

Karl Knechtel: Black takes the ko first, can extend backwards on the first line for several moves if desired, or just connect at a later... in which case White will eventually have to spend two moves capturing Black's throw-in stone before she can fill (i.e. Black implicitly gets more virtual threats too).
