 | Example 1 2 v 24,24 |
"If black is unlucky enough to roll 1-1, he won’t be able to move, and all of the 4 pips he rolls will be wasted. The immediate cost of this possibility is 4 pips in 36 rolls, or 0.11111 pips on average."
He could only use 2 of them anyways so is it correct to count it as 4?
I see what you're saying -- black can only move 2 spaces anyway, so how could his wastage be more than that? But wastage comes from rolled pips that go unused. Here black rolled four pips and all of them went unused.
Even without a block in the way, black's 1-1 will waste two pips. (Two pips are used to take the checker off and the last two pips go unused.)
