Tailor-made alterations

In Response To: Nice position !! (neilkaz)

it seemed nextish to play 4/1 4/2* in spite of the extra roll
As it turned out, taking a checker off 3/1 3/off increased wins by only this much.
If Blue has 10 checkers left 4/1 4/2* is better .. because putting White on the roof wins more gammons!
The score (after 0 games) is: White 0, Blue 0
Move number 8: Blue to play 31
