Go up one level in this thread


In addition to the higher branching factor, I guess that the quality of the
evaluation function is very important. And in chess even the best evaluators are
close to guesswork in critical positions. To get some semblance of a quality
book for chess one could maybe use some kind of Berliner B* search, or Lambda
search. But the insurance depth would still be only one additional ply than
ordinary search. I.e. one doubling of search time approximately. As an aside,
the Dragon is hardly the most forcing of openings. Better some Kings Gambit or
the Poisoned-Pawn Najdorf (lots of only moves in most variations.).
