I'm glad you're having fun, but I should add that 6.7 isn't the best tactical setting I have by any margin. I have many that are far stronger. The problem is that they also didn't play the best chess, which is why no one here ever heard about them. Below is one of my best tactical settings, possibly the best, and that doesn't play a bad game either. The reason I didn't pursue it is due to evaluation quirks I found with the [MISC_58] switch. Try it though, as you might like it: [Personality = PDSD57.ENG] * Search & Destroy v.5.7 (September 2004) [AUTHOR = Albert Silver] [Pawn Value = 98] [Knight Value = 98] [Bishop Value = 98] [Rook Value = 98] [Queen Value = 98] [My Queen = 101] * new since September 1, 2004 [King Safety = 165] [Mobility = 115] [Pawn Structure = 100] [Passed Pawns = 105] [Pins = 105] [Bishop Pair = 100] [Chess Knowledge = 100] [Attractiveness = 103] [Attacking = 107] [Strength of Play = 100] [Draw Contempt Factor = 0.00] [Selective Search = 100] [Search Technique = NULLMOVE] [Engine Learner = off] * off|on [Book Learner = off] * off|passive|moderate|strong|aggressive [Position Learner = off] * off|on [Extended Book Learner = off] * off|read|write|read&write [Clear Hash Table = Always] * Always|Never|PB only [Pruning = MISC_17] * [Pruning = MISC_14] * Queen ending (new style) [Pruning = MISC_25] * [Pruning = MISC_37] * [Pruning = MISC_40] * [Pruning = MISC_52] * [Pruning = MISC_66] * [Pruning = MISC_69] * [Pruning = MISC_78] * adaptive nullmove R=2/3 [Pruning = MISC_03] * move ordering speedup [Pruning = MISC_21] * Lazy Eval (tuning) [Pruning = MISC_58] * Recalculate passed pawns [M58_Table = normal] * normal|midg|endg|strong [Checks Depth = 1] * limit QS checks to 1 ply [Pruning = MISC_30] * extend singular checks [Pruning = MISC_42] * extend first check too [Pruning = MISC_47] * King Safety extension [Pruning = MISC_26] * Endgame extensions [Pruning = MISC_07] * [Pruning = MISC_65] * research fail-high-error one ply deeper (!)
