In Response To: Opening 43 at GS — Question about GnuBg data (Taper_Mike)

Thanks to Nack Ballard for sending this GnuBg Supremo rollout made by David Rockwell. Double thanks to David for making it in the first place. Although Nack credits Stick, it is likely that David rolled it out on assignment from Stick. The file name carries David’s initials. In addition, Supremo rollouts using the seed 1 were one one David’s MOs back then. Here is how I resolved the conflicting reports of GnuBg rollouts for an opening 43 at GS.
