First – what is a beat? The simple answer is that it is a one tempo percussive action delivered to an opponent’s blade. Traditionally, beats have been classified with presses and froissements as attacks on the blade because the focus of the action is the opponent’s blade, not his target area.
See that I didn’t state that it is an activity to expel a rival’s cutting edge from a line, or that it is a piece of an assault. That is on account of a beat can have an assortment of strategic results:
(1) straightforward disturbance – these are little beats conveyed to the rival’s edge, regularly with the external quirk, with the purpose of irritating the adversary and connecting with her consideration.
(2) beats to draw a response – these are more significant beats with weakness to waist of your edge to make the rival respond as planning for the fencer’s assault or countertime activity.
(3) dangerous beats – beats with the internal shortfall to upset a creating assault arrange or to deny a rival the capacity to utilize a line (in this way expanding his consistency).
(4) beats as a feature of an assault – beats with the internal shortfall or waist of your edge to uproot the rival’s cutting edge, opening the line for your quick assault.
(5) beats as a repel or as a major aspect of hostile countertime (as a beat straight push executed on the rival’s stop hit). Under the present guidelines a beat adequately can’t be a repel in thwart or saber (a repel must be executed with the lower 33% of the sharp edge). Be that as it may, a beat surely will dislodge the adversary’s cutting edge from the line of the assault, and the beat repel has for some time been an acknowledged some portion of the fencing ability set. Comprehend that in thwart and saber you can’t just beat into a rival’s beat assault. The beat assault will be given right of way. On the off chance that the rival beats your cutting edge, you should beat the assault falling off the beat so that there is a noticeable arrangement of beat-beat. In any case, who knows how that activity will be called by the ref.
An all around conveyed beat has certain attributes in each of the three weapons. The a greater amount of these that are available, the better the likelihood of accomplishment in accomplishing the objective.
(1) the beat agrees to the necessities of the principles. In epee, there are no necessities, however in thwart and saber beats must be conveyed on the 66% of the sharp edge uttermost from the rival’s watch (this has been re-imagined in the tenets as the quirk, rather than the long-standing use that the shortfall is the forward portion of the cutting edge in thwart and the edge past the Y, T, or I in a saber edge) (see rules t.56.4 and t.78).
(2) the beat begins when the edges are not in contact. On the off chance that the edges are in contact, bringing your sharp edge off the adversary’s will give her a reasonable sign of what you plan to do.
(3) the beat is not loaded or positioned – pulling the cutting edge to the side to acquire it back the beat permits stop hits in epee, stop cuts in saber, and derobements in every one of the three weapons.
(4) the beat applies adequate power for its motivation. In any case, it is not a beast drive activity planned to push the adversary’s edge over the room. Timing, enough compel to move the edge from the line however no more, and speed are more critical than just crushing the cutting edge as hard as possible.
(5) the beat is fast – to be fruitful beats must give the adversary as meager cautioning as could be allowed. Fast fingers, with some wrist activity, are fundamental.
