If people prefer a text file for personality tuning I can switch over to that style. Making a UCI Engine play down its strength is an interesting idea that is a UCI-2 option that I will look into soon. Thank you for the idea as I am sure many feel the same way. Here are the tuning options so far. The extension related options will be seen in the next version released in a few days. I hope to have more options soon as well and am alway open to suggestions. option name Hash type spin default 16 min 4 max 1024 option name Ponder type check default false option name OwnBook type check default true option name BookFile type string default book_small.bin option name Extention cap type spin default 16 min 16 max 48 option name Check extention level type spin default 16 min 0 max 32 option name Recap extention level type spin default 16 min 0 max 32 option name Pawn to 7th extention level type spin default 16 min 0 max 32 option name Threat extention level type spin default 16 min 0 max 32 option name Single reply extention level type spin default 16 min 0 max 32 option name Use same threat extentions type check default false option name Exclude Same threat from cap type check default false option name Same threat extention level type spin default 8 min -16 max 16 option name NullMove Pruning type combo default Always var Always var Fail High var Never option name NullMove Reduction type spin default 3 min 1 max 3 option name Verification Search type combo default Always var Always var Endgame var Never option name Verification Reduction type spin default 5 min 1 max 6 option name History Pruning type check default true option name History Threshold type spin default 60 min 0 max 100 option name Rebel Reduction type check default false option name Futility Pruning type check default false option name Futility Margin (Depth=1) type spin default 300 min 0 max 3500 option name Futility Margin (Depth=2) type spin default 500 min 0 max 3500 option name Futility Margin (Depth=3) type spin default 975 min 0 max 3500 option name Delta Pruning type check default false option name Delta Margin type spin default 50 min 0 max 1000 option name Quiescence Check Plies type spin default 1 min 0 max 2 option name Piece Activity type spin default 100 min 0 max 400 option name King Safety type spin default 100 min 0 max 400 option name Pawn Structure type spin default 100 min 0 max 400 option name Passed Pawns type spin default 100 min 0 max 400 option name Use King Tropism type check default true option name knight tropism type spin default 4 min 0 max 10 option name bishop tropism type spin default 2 min 0 max 10 option name rook tropism type spin default 2 min 0 max 10 option name queen tropism type spin default 4 min 0 max 10 option name Fruit Lazy Eval type check default true option name Fruit Lazy Eval Margin type spin default 200 min 0 max 900 option name Fruit Exchange Bonus type spin default 30 min 0 max 100 option name Fruit King Safety type check default true option name Fruit King Safety Margin type spin default 1600 min 500 max 2500 option name Opening Pawn Value type spin default 90 min 0 max 1000 option name Opening Knight Value type spin default 320 min 0 max 1000 option name Opening Bishop Value type spin default 325 min 0 max 1000 option name Opening Rook Value type spin default 500 min 0 max 1000 option name Opening Queen Value type spin default 975 min 0 max 1000 option name Endgame Pawn Value type spin default 100 min 0 max 1000 option name Endgame Knight Value type spin default 320 min 0 max 1000 option name Endgame Bishop Value type spin default 325 min 0 max 1000 option name Endgame Rook Value type spin default 500 min 0 max 1000 option name Endgame Queen Value type spin default 975 min 0 max 1000 option name Bishop Pair Opening type spin default 50 min 0 max 1000 option name Bishop Pair Endgame type spin default 50 min 0 max 1000 option name Queen Knight combo type spin default 20 min 0 max 1000 option name Rook Bishop combo type spin default 20 min 0 max 1000 option name Contempt Factor type spin default 0 min -1000 max 1000 uciok Thanks, Ryan Benitez
