I have a testversion to see if I can put settings for [Center Control], [Bishop
Mobility], [Strong Squares] and [Right to Move] in Rebel Betazoid. I'm just
testing it here but it is either a hard position, or the settings are no good,
or Black must have some hidden resources...

With
[Center Control = 20]           * 25
[Bishop Mobility = 25]          * 25
[Right to Move = 75]            * 75
[Strong Squares = 125]          * 125

I get

[D]r1b1r1k1/pp3p1p/2pB1qpb/4n3/2P1PP2/1PN3nP/P1NQB1P1/2KRR3 w - - 0 1

In other words Experimental Rebel thinks Black is now better even from White's
point of view (The evaluation is slightly asymmetrical/biased)

But on the other hand, Q3 for tactics thinks that Chessmaster's 22.Rf1 is the
best move:

01:00:53.7	0,55	14	750597255	Rf1 Nxf1 Rxf1 Nd7 g4 Qh4 g5

They can not both be right, unless they are picking the right move for their own
style.
