OK， new question. In this game:

1) would you play the double hit on the 6-4 roll?
i didn't, because without the cube, i didn't feel that taking the risk of "squandering" a 10 roll for no chance of the increased reward of a gammon was worth it...leading to the second question...

2. could this be one of the situations where you'd play differently based on a cube or not? If it's not, what's the most striking opening example you can think of?

Also, playbunny, i don't understand the terminology of "gaining blocks", hoping for something didactic here!
