Unfortunately I am not going to give more than few hours per day of computer time for it because I use my computer for other purposes. No news from the last update. I think to include Tiger14,Gambit2,Deep Fritz, Crafty at depth 3-10 I think to play only matches between different programs when the difference in depth is at most 3 and it is going to give for every player: 420 games for depth 6,7 360 games for depth 5,8 300 games for depth 4,9 240 games for depth 3,10 This process may take some months because of the fact that I am not going to use more than few hours per day and I do not promise to use the computer every day for this purpose. I am afraid games when the difference in depth is more than 3 are going to end often with the result 20-0 and this is the reason that I am not going to play them(we already had 19-1 result when the difference was only 1). Other people probably can reproduce similiar results but not exactly the same results because they probably do not have exactly the same set of tablebases that I have. Uri
