ed HAS done some styles that work on the base of my evaluations settings
and HIS search stuff.

IMO those styles are weaker, but HE believes in it.

the problem with many switches in rebel is that when you mix them with
others you weaken rebel.
there is IMO no easy way to find out about this WITHOUT TRYING IT OUT WITH EACH
COMBINATION of switches.

and this takes time, as you can imagine.

e.g.

this is a style ed likes:


[Personality = REBEL3.ENG]      * Rebel 12 (risky 1.00)
[Pawn Value = 98]               * 98
[Knight Value = 99]             * 99
[Bishop Value = 101]            * 101
[Rook Value = 102]              * 102
[Queen Value = 105]             * 105
[King Safety = 139]             * 139
[Mobility = 120]                * 120
[Pawn Structure = 95]           * 95
[Passed Pawns = 105]            * 105
[Passed Pawn King Tropism = 120]   * 120
[Traditional Isolated Pawns = 80]  * 80
[Progressive Isolated Pawns = 125] * 125
[Pins = 110]                    * 110
[Bishop Pair = 101]             * 101
[Chess Knowledge = 200]         * 200
[Attractiveness = 119]          * 119
[Attacking = 125]               * 125
[Strength of Play = 100]
[Draw Contempt Factor = 0.00]
[Selective Search = 100]
[Search Technique = NULLMOVE]

[Engine Learner = off]          * off|on
[Book Learner = aggressive]     * off|passive|moderate|strong|aggressive
[Position Learner = on]         * off|on
[Extended Book Learner = off]   * off|read|write|read&write

[Pruning = MISC_03]
[Pruning = MISC_29]
[Pruning = MISC_49]

[Pruning = MISC_09]
[Pruning = MISC_10]
[Pruning = MISC09_3.00]
[Pruning = MISC10_5.00]

[Pruning = MISC_17]
[Pruning = MISC17_DEPTH_10]

[Search Safety MIDG = 100]
[Search Safety END0 = 150]
[Search Safety END1 = 200]
[Search Safety END2 = 200]

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

[ANTI-GM = OFF]
[EVALUATION = NORMAL]
[Extensions (remaining)= 3]
[Extensions (checks)= 0]
[Extensions (captures)= 0]


IMO many switches in this style that are ON do not fit with my SEX.
e.g.  MISC 9/10 is not working together with SEX. it seems those
fail high reductions do not work with SEX.
Also i was not able to find out that MISC 29/49 brings ANY kind of progress
concerning strength.
