ballroom dance performed by four couples in a square formation
Square dance A square dance is a dance for four couples (eight dancers in total) arranged in a square, with one couple on each side, facing the middle of the square. Square dances were first documented in 16th-century England but were also quite common in France and throughout Europe. They came to North America with the European settlers and have undergone considerable development there. In some countries and regions, through preservation and repetition, square dances have attained the status of a folk dance. The Western American square dance may be the most widely known form worldwide, possibly due to its association in the 20th century with the romanticized image of the American cowboy. Square dancing is, therefore, strongly associated with the United States. Nineteen U.S. states have designated it as their official state dance.
Connect Four The solved conclusion for Connect Four is first player win. With perfect play, the first player can force a win,[6][7][8] on or before the 41st move[12] (ply) by starting in the middle column. The game is a theoretical draw when the first player starts in the columns adjacent to the center. For the edges of the game board, column 1 and 2 on left (or column 7 and 6 on right), the exact move-value score for first player start is loss on the 40th move,[12] and loss on the 42nd move,[12] respectively. In other words, by starting with the four outer columns, the first player allows the second player to force a win.
