May 12, 2019 at 16:25 comment added Russ Woodroofe Yes, those are tricky. Indeed, the NP-completeness proof for shellability puts such complexes to good use. It's also worth mentioning that the above idea is unlikely to be helpful with a complex that is sequentially Cohen-Macaulay, but not shellable. Still, I've found this approach helpful for checking conjectures (and it's easy to implement).
May 10, 2019 at 22:16 comment added Richard Stanley Note however (mathoverflow.net/questions/257792) that there are simplicial complexes with more than one facet such that one of the facets must come last in any shelling. Probably most partial shellings cannot be completed to a shelling.
