Chess, SBE is typically linear weighted sum of features

\({\sc Eval}(s) = w_1 f_1(s) + w_2 f_2(s) + \ldots + w_n f_n(s)\)

e.g., $w_1 = 9$ with
$f_1(s)$ = (number of white queens) - (number of black queens)

For chess, 4 ply is human novice, 8 ply is typical PC or human master, 12 ply is grand master
