The basic cribbage board consists of four parallel rows of thirty holes with two "storage" holes to hold the pegs before play begins. Two rows are on one side of the board and two on the other, each player owning one pair of tracks.

The standard game consists of one hundred twenty one points which are marked by each player advancing his scoring pegs up the outer of his two tracks as he pegs in play and scores his hand or crib. When the score reaches thirty the player's peg is at the top of the column. The next point scored moves the peg to the inside track and progresses downward from there. Between hole thirty and thirty one the player "turns a corner".

In some games, especially if a wager is involved, a bonus might be offered for the first player to reach a corner, thus the option to count them.

A corner also defines the "street" or column being travelled. For instance, the first thirty points is referred to "First Street" and after turning the corner the player is said to be on "Second Street" and so forth unto Fourth Street and "Out."

Ok,
I am a bit confused about scoring the go. I will present a couple of sample hands, could someone tell me if i am scoring them correctly?
****Hand One
Me: lay down 5, count is 25
Opponent: Go
Me: lay down 3, count is 28
Me: lay down 2, count is 30
Do i peg one only for the go, or 2, one for the go, then one for the next go
What if the 2 was a 3, making the count 31, would i peg 2 or 3
*****Hand 2
Me: i lay down a 10, count is 30
opponent: Go
Me: i can't play
Do i get a point for the GO?
