Stockfish 120316 for the Mac
This version has the latest commits and pulls and it will probe partial 6 man syzygy tablebases ( but not recommended). As an example, to probe knnvkpp you will need:

knnvkqq ... knnvkqp
knnvkrr ... knnvkrp
knnvkbb ... knnvbbp
knnvknn knnvbnp
with "..." representing the sequential tb's in between


surprisingly , the pawn does not have to be on the edge for black to get mated at the end...

Also, these patterns are learnable , it is not too different from the kbnk endings in how white forces the black k to the corner, but do not ever take that pawn

of course you have to make sure you pick right the corner...and sometimes, black will queen
