Tinkercad continues to have its upload problems, so it took until today to get the weekend's pair.

277. Faro. and 278. Loco. Also called the Argentinian Rook and Argentinian Bishop, these two pieces (along with the corresponding Knight and Queen -- Saltador and Señora, respectively) were invented in 2016 by Manfred Rittirsch for use in fairy chess problems; they've rarely been seen in an actual game until this year.

Argentinian pieces capture with a normal move, but must pass a hurdle in order to move without capturing. The distance before and after the hurdle can be anything, as long as the piece follow a straight line and jump exactly one hurdle.

As suggested by their alternate names, the Faro moves orthogonally (cRmpR), while the Loco moves diagonally (cBmpB).

The names, translated from Spanish, mean lighthouse and crazy person.

The added-on part of the dot inside a circle is intended to represent the Cockade of Argentina, one of the country's most recognizable national symbols.* My apologies to those in North America (and elsewhere) who associate that image with the Target department store chain.

(I'm thinking that maybe I should rework these pieces, with the circles a smaller diameter.)

The Señora, of course, compounds these two. (The Saltador moves like a normal Knight, but must have a piece in one of the two intervening spaces to move without capturing.) More Argentinian pieces could be extrapolated from all these, including Archbishop, Chancellor, Nightrider, and others.

*The most recognizable is the Sun of May, which consists of a sun with a face and 32 rays extended, alternating between straight and undulated, as seen in the center of the country's flag. While a beautiful  and singular icon, it's a bit too complex for this context.
