(c) To make a line is to get 3 of your pegs on one line in any way but diagonally, in which case the third or last peg moved to make the line can be at once removed to any vacant hole on the board.
Example.—By occupying holes 1 2 3, 2 10 18, 9 10 11; in fact any way but from corner to corner as 1 9 17 or 19 11 3.
If your adversary insists upon maintaining a peg in a hole to your great disadvantage, play your pegs so as to force him from it, having first prepared a hole for him to move into. That is to say, be careful that the hole you force him into does not attack your position, as—Black’s pegs in 2, 4, and 7; White’s pegs in 1 and 6; now Black, moving peg 4 to 3, forces White’s peg 1, which is compelled to move to hole 8, and so captures Black’s peg 7. On the contrary, if Black occupied holes 2, 6, 7, 9, 11, and White holes 1, 4, 5, by Black playing peg 11 into 3, White’s peg 1 is forced into 8, and it being Black’s next move, he occupies hole 1 with his 9 peg, or 2 peg, and so captures the peg he forced. The great point is to place the pegs in a good position at the commencement of the game.
Rules.—1. Each player places one peg in turn, and when all are placed, moves in the same manner, but only as the lines run, and one hole at a time.
2. A force made during the placing of the pegs does not interfere with that player’s turn; that is to say, if White in playing the pegs occupies hole 1, and Black hole 3, Black would be forced by White taking hole 2 and would have to move, but would immediately afterwards place his peg as was his turn.
3. The placing of a peg gained from the reserve into the hole vacated by King peg does not count as a move, consequently any advantage so gained is nil.
4. The playing a peg when forced counts the same as its move, and reaps any advantage gained by occupying the hole it is forced into.
5. A forced peg, having the preference of 2 holes to move into, can be compelled by the forcer to occupy either.
6. A made block or made force is of no advantage; that is to say, if Black occupied holes 1 and 3, White could put a peg in hole 2 without being captured; or Black possessing holes 1 and 2, White could place a peg in 3 without being forced. The same applies to a peg when forced into such a position.
7. Any advantage gained in a move, and not noticed before the next move, cannot be counted.
