Assume that a GM has developed and memorized a viable opening repertoire for use against some specific chess program, such as Fritz on a PC. Assume also that the GM has reached a position at the end of one of his/her repertoire lines and is trying to prepare for an upcoming match with that computer program. Finally, assume also that the GM's home computer is exactly half as fast as the computer he/she will face in the upcoming match. Then, is there any reason why that GM cannot experiment with alternatives on the home computer until a forced win is found [from that position]? It might be necessary to let the home computer think twice as long as the computer will in the match, but that should not be a significant restriction when doing home preparation. This question boils down to the technical issue of whether or not the same moves would be found on a slower computer if the amount of time allowed was increased to compensate for the slower speed of the computer. Also, this question depends on the issue of whether or not chess computer programs, like Fritz, are deterministic during play [after exiting the program's opening book] versus the deliberate introduction of some form of randomness by the programmers. Finally, it is possible that the GM might prepare for a computer move which is better than the move the computer might actually play, due to allowing too much time for the move during home analysis. Can anybody shed some light on these technical issues? The answers might help everybody to understand the extent to which GMs [as well as the rest of us] can prepare for matches against computers.
