Hi Alexander, for the reasons you mentioned I trained my pattern system on games between weaker and stronger players some years back. That was for 9x9 board size where I used game records from cgos where both players had a strength of at least 1700 Elo and at least one player was stronger than 2400 Elo. Obviously you should only learn the moves of the players that are stronger than 2400 ELO here..
I got some significant improvements of it that time, although I can't provide numbers today. I didn't made comparable experiments for larger board sizes. - Lars On Wed, 2013-01-16 at 15:53 +0000, Alexander Kozlovsky wrote: > Hi everybody! > > Is it enough to use big number of hign-dan games > to build a strong pattern library for random playouts? > > I have suspiction the most useful patterns may be > gathered from low-dan games.
