John... i think i may have come up with a personality setting that is stronger also... here it is... Attacker/Defender 0 Strength of Play 100 Randomness 0 Max Search Depth Max Selective Search 6 Contempt for Draw 0.0 Transposition table [checked] Deep Thinking [checked] Material/Position 20 Control of Center 120 Mobility 120 King Safety 120 Passed Pawns 120 Pawn Weakness 120 Own Queen 8.0 Opposing Queen 8.0 Own Rook 4.5 Opposing Rook 4.5 Own Bishop 3.5 Opposing Bishop 3.5 Own Knight 3.5 Opposing Knight 3.5 Own Pawn 1.2 Opposing Pawn 1.2 Opening Book - PetrosianT so far in my testing... the results have been favorable... i had one game where this setting made a queen sac that won the game some 20 or so moves later...
