In rare cases, it may be settled by foul play. The party who did the offense must immediately withdraw. There are several kinds of infringement, but there are such as "two steps" "stuffing stuffed", "neglect neglect", "advance a piece to a place where it can not move", "two-hand pointing", etc. as a beginner's actual warfare .

You can not beat another step when there is a step in the same line. The state where there are two steps in the same muscle like the left side of the figure below is called "two steps (nipple)". In addition, as shown on the right side of the figure below, walking on the same line as "and" where you walked is not a two step.

It is foul's fun to strike a glove to clog the other ball. As an example, it is a case like to hit a place marked with an X in the figure below.

In addition, it is not foul fashion itself to strike a king while walking. Therefore, walking on the circle in the center of the figure below is not a foul. Also, moving the pedestal on the board and clogging it is called "stuffed pushing", which is also not foul. Therefore, proceeding to the part of Δ on the right side of the figure below is not a foul.

If you can win the ball, you have to point out the hand that prevents the champion, such as the ball escaping. It is foul to point the wrong hand while the champ is on. The figure in the lower left is a phase where I walked a step without noticing the champion by 15 horns. In addition, the figure on the bottom right is a kind of neglected neglect, now the second hand moved the Katsura between the first corner and the back of the ball. It is also a foul play, in a state that you can say that "you challenged yourself".

If you go to a place where the piece can not move, it becomes a foul. The left side of the figure below moved the corner to a position that is one way off. Also, as shown on the right side of the figure below, it is foul to say that there are pieces that can not be formed.

It is to move your piece even though your opponent's turn is on. This is also foul. On rare occasions, there are things that I pointed ahead even though I got better. This is also a kind of two-pointed pointing.

There are also foul funs such as "striking a piece where there is no place to go" and "senpai of successive champions", but since it is rare in beginner's actual warfare, I will omit it here.
