White looks alive to me because there's an eye around R16 and miai between dealing with the upper right and T15. The most confusing attack I can find is black S19, threatening ko, but white can respond with S18 and be fine.

Yes, I think that's right. During the game I misread and thought black could get a ko. I think maybe this is the most interesting line:

If Black is unaware of , , , and , he might think that would kill.
If one cannot see that white can live he might assume that white is dead

Well in the game I played the block at R18, which was ok anyway since I was winning and it makes some points (Bill: how many points? 4 or so?), but afterwards I realized I could've played elsewhere.
