Do you agree with that Robin?
I hope not, because it's wrong.

Would you agree with this:
 Ply = a half move        12 Ply = 6 .. half moves for each side.
A Total of 6 moves right?
It's correct to say for example:
The engine searched to a depth of 15 half moves, while some promising
variations were searched to 34 Ply.
I understand that.

Chessbase chose the definition of:
"One move for each side is considered one Ply"
It was describing the analysis function and what one "iteration" was.
That is also the context in which I used it.
So, in that context, and if you check my original Post
you can verify that.
Now using that definition, then the following makes perfect sense.
"The analysis module evaluates every possible move for a given
position 1/2 Ply at a time. That is one iteration."

Aside from that 'selectively' used definition to descibe a particular
function, it is not used.

Please review my original Post; my explantion as noted in this one,
and your kneejerk, inaccurate, rude, ignorant, response, & consider
who is spouting nonsense!
