I'm very interested if you can reach a final conclusion whether a) study is faulty b) stockfish is showing >+70 for drawn position.

In theory choice b) is not impossible, but in practice I've never observed it.

id also very much like to know. if i run stockfish on big h/w from say the queened pawn position for a fairly long stretch is there a decent chance it will resolve the position in some fashion (ie solve for absolute mate presuming it's correct). i ask you or other stockfish devs/experts because i'm not sure how good it actually is at solving for mate; i've just observed its very good at telling you when there is one (with scores such as these).

i've still got access to a 12 core beaut and could run overnight+ if you'd like.

This great study seams to be a mate in 23.
Here Houdini is a better help than Stockfish.
With a little help it gives
