Subject: retrieving the PV from hash questions

Author: Michael Henderson

I take care of the PV during the search, but I have been wondering about the
other method of getting the PV from hash.  Some of these are obvious
questions/answers but I would like to discuss them.

How do you know the real length of the PV?

Do you not usually get short PV's due to a hash miss?

If you don't know the "draft" (due to extensions) at any point in the PV how do
you know a hash hit with depth x is good?

How does the path info problem with hash interact with the pv hash extraction
method?

Does score backed up ever really go with the leaf position of the PV?

I've heard this method can sometimes lead to blunders in the PV?

Shredder uses this method?
