HAL plays 3-1. That probably means that he has several 1's.
At this point, you should
expect Adam to hit the 1. He should respect the 3 that Mike put (Mike
is the leader in their team). So, if by any chance Adam hits the
3, that would mean, 99.9% sure, that he doesn't have any 1's (again,
hypothetically, if Adam hits the 3)
