2. Chess walking route: including highway line and railway line. The road route is displayed in detail, and any chess piece can only take one step on the road line. Railway lines are shown in bold black. When there are no obstacles on the railway line, engineers can walk on the railway line at will, while other chess pieces can only go straight on the railway line and cannot turn at right angles.
3. Placement of chess pieces on the chessboard: including nodes and camps. The camp is a safe island. After entering, enemy pieces can't eat the pieces in the camp.
4. Overall layout of chess pieces: Before the game starts, the distribution of chess pieces is randomly placed by the system, all of which are facing away from the players, and no chess pieces are placed in the camp. Except for mines and military flags, all other pieces can be moved to change the initial placement position.
Extended data:
The original "military chess" has no established rules, and it forms a kind of "combat simulation", which is equivalent to the fact that in a war, a war commander often displays the military arrangement of the warring sides with some marks on the original map, and then reacts to the possible actions of the enemy to show the possible progress of the war, so as to choose the most beneficial action in actual war to achieve the purpose of the war.
This kind of "combat simulation" exists in all countries, and the content is similar: a picture that imitates the real situation, then several pieces indicate the strength, and then analyze what will be done.
