Personalities unclear

[tissatussa]

hi,

i successfully compiled your Irina v0.18 on Linux and i tested all personalities in CuteChess GUI, letting them play a 5m+3s game with White after 1.e4 c6 2.d4 a6!? which is this position : rnbqkbnr/1p1ppppp/p1p5/8/3PP3/8/PPP2PPP/RNBQKBNR w KQkq - 0 3

many personalities play a bad game, they sacrifice pieces with no compensation, their moves seem even random to me. But the 'default' personality 'Irina' plays a decent game.

in person.c i find this table with values for 'Rnd', 'Adv', 'Cap', 'Mat', 'San', 'Q', 'R', 'B', 'N' and 'book' :

//                                         Rnd   Adv Cap  Mat San   Q    R   B    N    book
if(set_personality(value, "Monkey",   100,  0,  0,  0,  0,  0,  0,  0,  0, false)) return;

if(set_personality(value, "Advance",    0,100,  0,  0,  0,  0,  0,  0,  0, false)) return;
if(set_personality(value, "Capture",    0,  0,100,  0,  0,  0,  0,  0,  0, false)) return;
if(set_personality(value, "Knight",     0,  0,  0, 60, 40,  0,  0,  0,  0,  true)) return;

how did you pick those values ?
are they just experiments ?

btw. "Monkey" and "Random" are equal, all their values are 0, except 'Rnd' is 100.

These personalities are meant to be played by someone who is just starting out, they are mainly intended for children, in the LucasChess program there is a section where user play precisely against them in a children's mode, and that's why I created them.
