Wrong! I won't let you get away with this either!
You think Chessbase doesn't understand their Modules?
You think Chessbase Programmers don't understand Programming?
You, have a lot to learn!

Using the Tools THEY suggest, and the Method THEY suggest, is
exactly what I have Posted!

I get a lot of "Trash Talking" over here; and I'll "respond" in kind,
to the willful ignorance of those who attack me with garbage!

How long is long....? Subjective huh?

I said, and I say again..
"USE the TOOLS" at your disposal!

Using Multiple lines, generating 6, because the King ONLY has 6 possible
moves...  wait a decent amount of time.. 10 minutes, which is a Depth of search
to about 18 or 20 Plies, then, FOCUS on the Main pV, and search THAT one in
depth.   If, in the deeper search the Program finds a better move, the line will
be overwritten, however I doubt it will switch.

There is NOTHING wrong with my 'Concept', it is the CHESSBASE concept.

This is not Rocket Science!

I agree.... you get an "F-"

Because obviously you, don't understand what is going on.
