The Spanish game of mus (pronounced like “moose”) is thought to have originated in the Basque Country near the border of Spain and France. References to the vying game first begin to appear during the mid-18th century, although the game itself was undoubtedly played earlier. It’s also still played today in Spain and France and turns up elsewhere in Europe as well as in Central and South America.
The game of mus strikes me as being more like bridge or spades than poker, mainly because it is played by a couple of two-player teams with partners sitting opposite one another.
