H = ΔR -1 (maximum 9 stones)
Here’s another point of discussion.
Personally, I prefer uncapped handicap, but I hope that the boards won’t be unbalanced enough for this to become a practical concern.
Also, if we have uncapped handicap but mandatory standard placement then we’ll have to invent new standard placements for 10+ stones, like my 13-stone and 16-stone formations.
