Subject: Are 6-piece EGTB's worth it?

Here's a small example of "perfect play" using the KRPP-KR tablebase. It's not
the only path that leads to mate, there are a few possible branches along the
way, but there are no shorter paths. How many engines playing black without
6-piece EGTBs could get a win against an engine playing white with 6-piece
EGTBs? Not many, if any. Take a look
