The two players commence on an equality, without scoring any points
for the last, retain four cards in hand, and throw out two for crib.
At this game it is of advantage to the last player to keep as close as
possible, in hope of coming in for fifteen, a sequence, or pair,
besides the end hole, or thirty-one. The first dealer is thought to
have some trifling advantage, and each player may, on the average,
expect to make twenty-five points in every two deals. The first
non-dealer is considered to have the preference, when he gains ten or
more the first hand, the dealer not making more than his average
number.
