I suspect it had KPPKP, but not KQPKP, which explains why it happily kept a
mate-in-X position on the board instead of queening the pawn (which would drop
the score to "only" +10).
Note that it still should have seen the correct mating line in the search, but
perhaps Shredder doesn't bother searching if it finds tablebase mates at the
root.
