Thanks, I did have a look but though it was good generally it would not have answered my specific problems. Whilst slowly searching back on the site though I found two replies you made to (what appears to be) an identical issue and your answers there covered it exactly (especially the second posts comments about the +1 for each prisoner essentially making it neutral to white to carry on playing - as that was also something I found confusing).
If you could include examples involving those two comments (where not already addressed) then it would be very good…
Forgot the link - earlier answer
