I rolled a 1 and a 6. As the board stands at the time of my roll, I cannot play the 6 but I can play the 1 and I can play that 1 in 4 different places. However there is one play where IF I played the 1 with a particular piece THEN I would be able to play the 6. I say the rule of the higher number being played if possible is applied as the board stands at the time I rolled and therefore I can only play the 1 and I lose the 6, as there are two or three locations where I can play the 1 and then the 6 is impossible to play. There is only one piece on the board which I could play the 1 first and that would then enable me to move the 6. Am I right or does the rule of forced play also include playing your die rolls in a particular order and in a particular place?
