It looks like this:", + "", + 0}; + +char *intro2[] = { + "", + "\n Although not indicated on the board, the players' homes are", + "located just to the right of the board. A player's men are placed", + "there when they are removed from the board. The board you just", + "saw was in it's initial position. All games start with the board", + "looking like this. Notice that red's pieces are represented by the", + "letter 'r' and white's pieces are represented by the letter 'w'.", + "Also, a position may have zero or more pieces on it, e.g. posi-", + "tion 12 has five red pieces on it, while position 11 does not", + "have any pieces of either color.", + "", + 0}; + +char *moves[] = { + "\nMoves and Points:", + "\n Moves are made along the positions on the board according to", + "their numbers. Red moves in the positive direction (clockwise", + "from 1 to 24), and white moves in the negative direction (coun-", + "terclockwise from 24 to 1).", + "\n A turn consists of rolling the dice, and moving the number of", + "positions indicated on each die. The two numbers can be used to", + "move one man the sum of the two rolls, or two men the number on", + "each individual die. For example, if red rolled 6 3 at the start", + "of the game, he might move a man from 1 to 7 to 10, using both", + "dice for one man, or he might move two men from position 12, one", + "to 15 and one to 18. (Red did not have to choose two men start-", + "ing from the same position.) In addition, doubles are treated", + "specially in backgammon. When a player rolls doubles, he gets to", + "move as if he had four dice instead of two. For instance, if you", + "rolled double 2's, you could move one man eight positions, four", + "men two positions each, or any permutation in between.", + "", + "\n However, there are certain limitations, called 'points.' A", + "player has a point when he has two or more men on the same posi-", + "tion. This gives him custody of that position, and his opponent", + "cannot place his men there, even if passing through on the way to", + "another position. When a player has six points in a row, it is", + "called a 'wall,' since any of his opponent's men behind the wall", + "cannot pass it and are trapped, at least for the moment.

Once a man is removed, he stays", + "off the board for the duration of the game. However, a player", + "cannot remove men until all his men are on his 'inner table,' or", + "the last six positions of the board (19-24 for red, 6-1 for", + "white).", + "\n To get off the board, a player must roll the exact number to", + "get his man one position past the last position on the board, or", + "his 'home.' Hence, if red wanted to remove a man from position", + "23, he would have to roll a 2, anything else would be used for", + "another man, or for another purpose. However, there is one ex-", + "ception. If the player rolling has no men far enough to move the", + "roll made, he may move his farthest man off the board. For exam-", + "ple, if red's farthest man back was on position 21, he could re-", + "move men from that position if he rolled a 5 or a 6, as well as a", + "4. Since he does not have men on 20 (where he could use a 5) or", + "on 19 (where he could use a 6), he can use these rolls for posi-", + "tion 21.

Such moves are", + "counted as if the bar is one position behind the first position", + "on the board. Thus if red has a man on the bar and rolls 2 3, he", + "must move the man on the bar to position 2 or 3 before moving any", + "other man.
