Unclever use of language and expresions. The author of this text means
barpoint (= 7-point and 18-point), when he/she writes 'bar'.
0 0 0 0 0 = player on roll has no chequers on ace to 5 points
11111 0 = 5 chequers on the 6 point
*0 = empty bar (means barpoint = 7-point)
111 0 = 3 on the 8
0 0 0 0 = no others in our outfield
11111 0 = 5 on the midpoint
0 0 0 0 0 = none in the opponent's outfield
0 0 0 0 0 = or in opponent's board, until...
11 0 = two on the 24 point
0 = none on the bar (This is how many's on the bar)
0 0 0 0 0 = opponent has no chequers on ace to 5 points
11111 0 = 5 chequers on the 6 point
*0 = empty bar (means barpoint = 7-point)
111 0 = 3 on the 8
0 0 0 0 = no others in opponent's outfield
11111 0 = 5 on the midpoint
0 0 0 0 0 = none in our outfield
0 0 0 0 0 = or in our board, until...
11 0 = two on the 24 point
0 = none on the bar (This is number of checkers on the bar)
