Just a little comparison between GLC books. The original website version and one I call random. The latter is basically a collection of GM games with minor modifications (22000 games, 24 plies deep). It outperforms my previous attempts, albeit based on flimsical evidence, which is very encouraging indeed
. Why bother with more or less thorough fiddling when it only takes 5 minutes. Needs more testing though with different opponents and timecontrols. Maybe it can be improved without falling apart.Program Elo + - Games Score Av.Op. Draws
