I wrote..
"I'd be interested in any and all comments, and your own personal experiences
with Databases, Engines, etc. if you'd care to share. Some may have some good
ideas on how best to use the Computer to study Openings. Correspondence players
for sure. I'm sure Komputer Korner would appreciate it too..
I was hoping Robin would read this, and make a positive contribution.
Instead, he prefers to nit-pick and focus on something he did not understand.
What a waste...

As a Player, against a human or computer,
 if I play 1. E4 that is a move! Not a half move.
 It is 1 move.. 1 Ply
A human will evaluate a few important responses, based on experience.
A computer evaluates every possible response, and there are 20 possible moves
it evaluates. 16 pawn moves and 4 knight moves.
It will rank them in order of best move first as determined by the mini-max
algorithm.
That is one complete iteration.
It will continue to do so one half move at a time, or one Ply, until it is
required to move,
and then will play the PV it considers best,  at that point in time.
Some here are trying to say 1. e4 e5 is considered a move and = 2 Ply
Fine... You can call a Dog's tail, a leg, but that doesn't mean a dog has 5
legs.
1. e4 is a move = 1 Ply
2. e5 as a response is 1 move = 1 Ply

So a half move for each side does = 2 ply
Now I hope we can move on here...
