Position 1:

Double risks Blue's equity from 7a1c, that's 9%

Double for the match potentially gains equity from 3a5a, 65% to 100%, when he wins the match with the 8cube: difference of 35%.

So, to double, Blue needs to have at least 9/(35+9), slightly over 20%.

He wins with 8 numbers[33, 44, 55, 66, 65, 64], 8/36=2/9=22.2%

Since 8cube is for the match,White should take if he wins more often than from 5a3a [35%], which he does.

Position 2:

White wins when Blue misses with one of 13 numbers [all 1s plus 32], that's 36.1%

Since this is better than roughly 35% equity he would have by dropping, he should take.
