Indeed, the continuations are for amusement only.

If you look at the Brainy project on my ftp site (written 6 months ago), you
will see that in the binary format I don't bother with the pv *at all*.  I store
only the pm, bm, and am.

Furthermore, I would always do a request of all positions forward one ply from
where I am standing.  And for those that look best, do a request for the
positions forward from there.

The way you use the data to search is limited only by your imagination.  And
with 6+ million pieces at long time control and 60 million at fast, there is a
prodigious amount of it.

Tons of crap or tons of angel-food-cake?

Time will tell.
