It is not as effective as book learning, where book learning helps it favor/avoid book lines that are generally known to be reasonable. With "position learning" it behaves like "electric shock therapy" where it makes a non-book move, gets into trouble a move or two or three later, and will therefore try a different move next time. But it might take many such attempts to find the one good move or such... >> First, my opening book has several >>*thousand* games with f3 in it. > >I thought that nobody plays it. >I know that even in the powerbook of fritz5 there is no 1.f3 > >Uri my book comes from about 700,000 games.
