I can't remember if you are in the USA or not, but the "last 2" always includes the 9. Its very well understood and clear in gambling circles in the USA.So many damn questions.
Are we including the 9 as the last two?
It can possibly be 5,6,7 if the 8 is off the table if we don't include the 9
People can hear this as 7 out.
I could go on and on.
The key with this game is the rules need to be clear.
