La unua mencio de la ludo Fencing troviĝas en The Shockwave Rider de John Brunner, kiu estis publikigita en 1975.

En distopia 21a jarcento la protagonisto Nick Haflinger fuĝas de registaraj oficistoj, kiuj volas misuzi liajn mensajn kapablojn por militistaj celoj. Por resti nekonata de militistaro, registaro kaj ĉionscia datuma reto, li dum la fuĝo regule ŝanĝas sian identecon kaj provas protekti sin per siaj esceptaj komputilaj kapabloj. Tio tamen ne eterne povas funkcii, kaj tiel konfrontiĝas ĝisfunde diversaj mondorigardoj.

The Shockwave Rider montras Fencing kiel agnoskita maniero pruvi genialecon. La reguloj tie estas la jenaj:

"Inter alia the Handbook of the National Association of Players at the Game of Fencing states:

The game may be played manually or electronically.

The field shall consist of 101 parallel equidistant lines coded AA, AB, AC... BA, BB, BC... to EA (omitting the letter I), crossed at 90° by 71 parallel equidistant lines 01 to 71.

The object is to enclose with triangles a greater number of coordinate points than the opponent.

The players shall toss or draw for red or blue; red begins.

At each turn each player shall claim two points, one by visibly marking it in the field, the other by entering its coordinates in a list concealed from the opponent (but subject to scrutiny by a referee in match play).

After at least 10 points (5 red, 5 blue) have been visibly claimed, having claimed his visible point for that turn either player may forego the option of claiming a concealed point and attempt to enclose a triangle by connecting three of his visibly claimed points. Prior to doing so he must require the opponent to enter his concealed points in the field. He may then enclose any triangle that does not include a point claimed by the opponent. A point claimed in a concealed list, which proves on inspection to have been claimed visibly by the opponent, shall be deleted from the concealed list. A triangle may enclose a point claimed by the same color. A point once enclosed may not be claimed. If a player claims such a point in error he shall forfeit both the visible and the concealed point due on that turn.

If a player finds, when the opponent's concealed points are entered in the field, he can enclose no valid triangle, he shall at once enter all his own concealed points, after which play shall proceed normally.

All triangles must have sides at least 2 units long, i.e. two adjacent coordinates cannot serve as apices of the same triangle, though they may serve as apices of two triangles of the same or different colors. No coordinate may serve as the apex of more than one triangle. No triangle may enclose a point enclosed by another triangle. A coordinate claimed by the opponent which lies on a horizontal or vertical line between apices of a proposed triangle shall be deemed included and renders the triangle invalid. A coordinate claimed by the opponent which lies on a true diagonal (45°) between apices of a proposed triangle shall be deemed excluded.

Scores shall be calculated in terms of coordinate points enclosed by valid triangles. An approved device shall be employed such that as each triangle is validly enclosed its apices may be entered into the memory store of the device and upon entry of the third apex the device shall unambiguously display the number of points enclosed. It shall be the responsibility of the player to keep accurate record of his cumulative score, which he shall not conceal from the opponent, except in matches played for stake money or on which there has been wagering or by mutual agreement of the players, when the cumulative score may be kept by a referee or electronically or mechanically, but in such cases there shall be no grounds for appeal by either player against the score shown at the conclusion or at any stage of the game.

It is customary but not obligatory for any game in which one player's score exceeds that of the other by 100 points to be regarded as lost and won."

La reguloj en nia programo laŭeble kongruas kun tiuj reguloj, sed ni devis iom kompletigi ilin, kaj elektis aldoni konfigureblon de kelkaj valoroj.
