Lines Of Action
by Sol Guber

There are many action board games in which the possible moves are very dependent on the previous moves. The most famous of these is OTHELLO, where each move will change the configuration of the board, and a whole new strategy is needed. LINES OF ACTION by Claude Soucie is related to OTHELLO, but it is both more complicated, and simpler to play. Figure 1 shows the board at the beginning of play. The object of the game is to have your men touching one another vertically, horizontally, and diagonally. You can also take the other person, but if he has only one man left, he automatically wins (one man always touches itself). Also, the fewer men there are on the board, the easier it is to win. The play of the game is simple. Each person, in turn, moves any man to another spot on the board. The direction that a man can move, and the number of squares that he can move, depends on his position on the board, and on the position of all the other men. A man can move horizontally, vertically, or diagonally the same number of squares as there are men in that direction. Let me explain this further. Looking at Figure 1 again, observe the WHITE man at B2. He can move horizontally, vertically, diagonally right, and diagonally left. In his horizontal row , there are six men. Thus, he can move (in theory) six squares to the left, or six squares to the right in a horizontal manner. There are two men in the vertical column, so he can move two squares up, or two squares down. There are two men in the diagonal left column, so he can move two squares in that direction. There are two men in the diagonal right, so he can move two squares in that direction. During play, you can see all the possible moves of a man, by moving the cursor to that man, and pressing the trigger. These are all possible moves. There are limits to the moves that can be made in the actual game. You cannot move off the board. You cannot move and land on your own man. You can jump over your own men, but you cannot jump over an opponent's man. You can land on your opponent, and he is removed from the board. Otherwise, the moves can be made in any manner.
Let me go into the way that the game is played. When the game is started, there is a question regarding instructions. A "Y" or "N" answer is expected. The computer asks for the names of the two players. The game can be played at two levels of difficulty. At the bottom of the screen, all the possible moves of any man can be determined by the Computer, and shown. If you do not want this to be done, answer the question with an "N." When it is a person's turn, his name will be shown at the bottom of the screen. White uses Joystick 1, and BLACK uses Joystick 2, to move a flashing cursor on the screen.
If the direction option is on, the cursor is moved to the man you wish to examine, and the trigger is pressed. The bottom display changes, and a marker is put on that man. The cursor is then moved to either the position to which you want to move that man, or to another man of the same color. Then the trigger is pressed. If it is to a man of the same color, the old marker is moved, and the information on the screen is updated. If it is not to a man of the same color, the move is checked to see if it is a legal one. If it is not. the move must be taken over. If it is a legal move, the man is moved to that square and removed from the old square. The board is checked to see if anyone has won, and then it is the other person's move. The game continues until someone wins.
The game has a large amount of complexity to it, yet it is very simple to learn. To help the beginner, there is the option to show on the bottom of the screen all the possible moves. For the advanced player, this is too distracting, and is not needed. The strategy of the game involves all the different men that can be moved. The decision whether to jump an opponent and remove him from the board is tempered with the idea that the fewer men on the board, the easier it is to win. Since the object of the game is the same for both players, each play must be both offensive and defensive at the same time.
To go through the working of the strategy, let's review the play of a game. In Figure 1, the men are set up as they would be at the start. The WHITE player is conservative, and plans his moves carefully. BLACK plays a more reckless game, and keeps trying to remove WHITE's men. The first move by WHITE is from A4 to C4. The man on A4 can move six squares in a horizontal position, and two squares in each of the vertical, the left diagonal, and the right diagonal positions. He has moved two squares downward in a vertical manner. On his next move, if he so wishes, he can move back to his original square. The BLACK man on C1 can move six squares vertically, three squares horizontally, and two squares either left diagonal, or right diagonal. He wishes to move three squares horizontally to the right, and lands on the WHITE man, removing him from the board in Figure 3. Again, this is a combination of plays. To be too aggressive, and to remove your opponent's men, will make it easier for him to win.
The play for the next few moves is rather straightforward. WHITE's next move is just a vertical one down. BLACK then moves horizontally from H3 to E3. White then moves vertically up from E8 to E5 in Figure 6. There are many more plays, and these are detailed in Table 1, which shows the whole game.
Let me skip ahead several moves to Figure 7, which corresponds to move 10 for WHITE. By Figure 7, Black has a decided advantage. He has ten of his eleven men touching, and all he needs is to move the man at H7 to the proper position, and he will win. White must prevent Black from bringing all his men together. To do this, White moves vertically up two to block BLACK's diagonal left move. If Figure 9, Black moves diagonally down from H7 to G8, so that on his next move, he can move diagonally left 3 up, and win the game. In Figure 10, White moves from G6 to F7 to block this move, since BLACK cannot jump over his opponent's men. Black moves from G8 to G6, to try some other method of winning the game.
WHITE now has a chance to make some counterattacks. In Figure 12, move 12, White goes from B 1 to D1. BLACK moves from G6 to G4, to win by a move to E2. WHITE moves from D6 to D3, on a vertically up move, removing the BLACK man on D3. White has now split up BLACK into two parts, and now BLACK has lost the offensive. In Figure 15, BLACK has moved from G4 to E2, to try to find some method of bringing his two groups together. WHITE moves from GI to G2, to try to take the man at E2. BLACK moves his man away from D2 to B2.
WHITE has changed the flow of the game. White now moves from G2 to E4, taking the BLACK man there. White is now trying to consolidate his men, in Figure 18. BLACK now moves from C2 to D2, and WHITE moves from D1 to El in move 16. In Figure 19, BLACK moves from A6 to C6, to try to get the man at E4. White counters by moving from F7 to C4, removing the BLACK man there. BLACK then moves from C6 to E4, taking WHITE. WHITE moves from F4 to F2. BLACK moves from E4 to F3, to try to take the man at F6, but WHITE does it first in Figure 26. BLACK moves from E5 to C3, taking WHITE there, and leaves himself open for WHITE's E1 to E3 move for the win.
I have gone through a game in a great deal of detail to show the flavor of it. It is very exciting, and contains portions of OTHELLO, checkers, and chess. The interesting part of the game is how each move changes the board for the other men. The major flaw is in Figure 27, where Black is so eager to move to C3 that he removes one man from that column, allowing WHITE a two move vertically, which removed the man. If the man were still at E5, then only a three vertical move would be allowed, and the man at E3 would have been safe.
I am willing to make cassette copies of this program for those that would like them. Please send a self addressed, stamped cassette mailer to me, plus \$3 to cover postage and handling.
