It is important when the computer evaluate it has adventage because in this way the computer can see more quickly if its evaluation is wrong. If its evaluation is right it is not very important if it miss something better because the result may be that it win more slowly > >> >>2)did a computer programmer try to find the probability his(her) >>program changes its mind if he(she) double the time of it >>as a function of time? > > >find the ICCA Journal article "Crafty goes deep" written by Monty >Newborn.

If your "best" move prediction isn't >very accurate, that needs to be fixed, rather than trying to >second-guess >yourself and waste time searching things you think are second best.. the point is if the "best" move evaluation is correct but there is something better for example I see that programs do not devote enough time to Chaos move in the 1974 computers championship against Chess4.0 Nxe6. I checked that after the forced line Nxe6 fxe6 Qxe6+ Be7 Re1 my programs evaluate the positon after some minutes as adventage for white while before Nxe6 the position is evaluated as advantage for black. it is clear that if white can tell black not to play some move Nxe6 is best so Nxe6 should be checked
