If you assume the opponent has a book that covers everything then there's not much to be done. However, if the plan works, he should be out of book early so the real fight between programs (not books!) can begin. >I remember that i surprised some years ago some engines with the very bad 1.a3 >then after 1..d5 which they all played diep would go 2.d4 and then pray the >opponent was out of book. > >I even remember how i fooled Nimzo.

Last I checked it still works, just doing stuff like 1.d4 2.c3 3.e3 4.Bd3 will take many engines out of book. >This just shows how important it is to visit world champs regurarly. Yeah but world champs is not the only place to gather experience. >Otherwise your 'tricks' are outdated quite some. My experience is that blindly following long book lines against programs with killer books, is certain death if your own book sucks. You _must_ deviate at some point and let the engine take over, preferably before it's completely lost. Just remember how Junior got smashed in the first game against Garry. Great example of a bad book line, Junior went for a long think out of book, but too late too little and the game was lost. -S.
