To actually add some content, is this a raise for fold equity or for value?

If for value, what worse hands are calling? I see next to nothing that is played this way.

If for fold equity, what hands are folding that beat you? A small flush? Set of Kings? Maybe the latter, maybe, but then I also don't know how likely Kings are. If he just had a flush draw or draw and a pair I'd be shocked if he calls a river raise. So just call.

Er, also a set of tens, maybe somewhat more likely, but I'd be surprised if he folds those often enough, or that he has them often enough.
