Subject: Forward pruning question

Author: Russell Reagan

Date: 17:05:14 12/04/02


Let me see if I understand what forward pruning accomplishes. I understand how
it works. Forward pruning only reduces the time to depth (and nodes to depth),
but it doesn't produce a more accurate score when searching to a fixed depth. In
other words, if you had a choice of the two following options:

1. 10-ply search using no forward pruning
2. 10-ply search using null-move

and all other things being equal, then choice 1 would potentially be the more
accurate 10 ply result. Is this correct?
