I've often wondered if it's always possible to tell whether any arbitrary boardstate is possible, and I came up with a few easy ways to tell how the board can't be legal without verifying that no set of moves can lead to it. Can you spot every illegality?

The ones I have: touching kings (and so many checks on the black king even though it's not his move), pawns on the first/last rank, 3 bishops even though no pawns have left the board

Edit: the h pawns passed each other
