[comp.sys.ibm.pc] Best chess program for the PC?

murphyn@cell.mot.COM (Neal P. Murphy) (10/30/89)

I am looking for the best available chess program written for MSDOS/PC.
Best meaning, among other qualifications:
    Best man/machine interface
    features that facilitate learning, what-if, and other functions
        that don't fall under m/m interface.

Please e-mail responses. If the majority of respondents so request,
I will post a summary.

Thanks,
NPN
