May be Tiger uses always 2 times more time to reach same depth. Why not >simple test with same time level for both!? > >Jouni There are some problems with it. 1)I use only one computer for my testing so the games are with ponder off 2)The target is not to find if tiger s better or worse than Fritz(ssdf does this job) The target is to see if there is deminishing returns from depth. I need to compare depth 13-depth 13 results with depth 13-depth 12 in order to see the returns from 1 ply. I already did it for small depths and did not find significant deminishing returns from depthes. Uri
