It is possible, that you get a better error message, when you just start crafty1.exe without GUI and look at the screen, what it says. >>Does crafty check to make sure that the entire set of a particular egtb is >>present even if I have set egtb=0?? or does the error commnets suggest that of >>the 5 piece egtb's I have that one or more are corrupted??? I believe, that it is possible to do a fast check of the TBs with the datacomp utility available from Robert Hyatt's ftp. It is included in the tbexe.zip. I have forgotten the path and the detailed instructions for the check, but remember, that it was not too difficult. Also, comparing the file sizes with the sizes in RobertHyatt's TB directory might be useful. >If you have a _partial_ TB, that is killing you. Don't put partial files >in with the others. Crafty will notice this and quit right after it starts. >Xboard won't be happy about it either... Perhaps there is a misunderstanding. I believe Les Fernandez asked about and incomplete set of 5-men TBs, and not about an incomplete single file. (Because he says, that he has 117 out of 220 files). But now to my question: What exactly is checked at the initialzation step in Eugene Nalimov's code? Is there some sanity check for the correctness of the found TBs done? If not, wouldn't a program only get problems, when it first accesses aa corrupt TB? If yes, what is checked for at the initialization step? I have the source, but nevertheless, the answer to those question is not obvious to me. Regards, Dieter
