That makes sense. I was implicitly assuming that if she didn't publish at b, then she still wouldn't at b+1, but maybe that's wrong. She probably cuts her losses at some point.

yup and i haven't solved it all the way through. I imagine there will be some results along the lines of:

if it's optimal to publish at (a,b) then it's also optimal to publish at (a+1,b)

if it's optimal to secretly mine at (a,b), then it's also optimal to secretly mine at (a,b-1)

or something like that. Haven't proved either result though.
