What constitutes a point-in-line?

According to Article t.10 of the FIE Rules of Competition, the in-line position is that "in which the fencer's sword arm is straight and the point of his weapon threatens his opponent's valid target." Properly done, the arm should be extended as straight as possible, and form a more or less continuous line with the blade, with the point aimed directly at the high lines of the target. Excessive angulation at the wrist or fingers negates the point-in-line.

Superfluous movement of the point also risks negating the line, especially in sabre. Derobements/trompements, however, are permitted. In foil and sabre, the point-in-line has priority over attacks that are made without first taking the blade.

With these weapons (but not with epee) it is forbidden to assume the point-in-line position before the command to fence has been given. In sabre, a point-in-line that hits with the edge is passe'; if a touch is registered with the edge, it is properly analyzed as a remise or counter-attack, ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
