I read with great interest your chat because it says me a lot. Sometime I am
lost in your too technical expressions. Anyway, if you could say how many moves
per ply, in general, you are forced to see it will be useful. I still could not
find directly efficency of my move ordering to offer my way as the good one.
Each time when I tryed my game against the best one, I found that my numbers
were not right because some wording I understood in a wrong way. So, how many
your game see in the ply where we have around 30 nodes, for instance?

Leonid.
