Hello Robert, I see not that you writing about my question, sorry for my other entry ! >that is because you don't know the program. I disable a good bit of the >time management code when pondering is disabled. But it _definitely_ hurts >it as it now doesn't assume it will save any time, which is not the way to >play chess... IE as a human I use more time when the game is complex, near >the beginning after I am out of my 'book'. Ponder=off disables this, and I >consider this bad, whether it plays well for you or not. >It is simply not the way to play matches... Because that is not the way the >program is developed, nor is it the way it is tested. And no it doesn't have to >blitz the last few moves, because I modified this several versions ago. But >just because it doesn't get low on time, doesn't imply that it is using its >time _correctly_. It definitely isn't... Hm, and another question ... Crafty play without ponder not with an correct time control, OK Why had Crafty before the time control is end enough time and why Crafty not blitz moves when I play 40 in 40 from moves 30 - 40 ! I think that Crafty had more time for move x and not more time for move y when ponder is off and the time control is correct. Then you have pros and cons. But I see that is good when I use longer time control and play not blitz matches. And for an statistic are this pros and cons not relevant. See the ELO ranglist on the winboard site and the results from over 600 Crafty games. But you are the programmer and you can say good or not good, but I can not see that Crafty play weeker, i mean weeker than the other programs with play without ponder (im mean ponder problem with time control problem, my english). In 4500 games we have 30 games with problems and 15 games with time problems. I looked in many log files and debug files and I must say that is not an big problem for the engines. But I think that engines on two PCs with ponder 20-50 ELO better play (the most engines). Another sorry for my other entry, I think you will not another writing about this problem. Thanks ! Kind regards Frank
