Crosswind

Crosswind is a connection game for two players: Black and White. It is played on the intersections (points) of an initially empty square grid (board). The top and bottom edges of the board are colored black; the left and right edges are colored white. Black plays first, then turns alternate. On your turn, place a stone of your color on an empty point without forming any of these patterns: Naked diagonal: a pair of diagonally adjacent stones of the same color with no other like-colored stone adjacent to both. Knight bend: a 2×3 pattern with three empty points, two like-colored stones in opposite corners and a stone of the opposite color in another corner. Long switch: a 2×4 pattern with four empty points, two black stones in opposite corners and two white stones in opposite corners. Loose crosscut: a 3×3 pattern with five empty points, two black stones in opposite corners and two white stones in opposite corners. Passing is not allowed, but, if you have no legal moves available, your turn is skipped. You win if there is a chain of orthogonally interconnected stones of your color touching the two opposite board edges of your color. To make the game fair, White will have the option, on their first turn only, to swap sides with Black instead of making a regular move. Notes Draws are possible. There are at least two different deadlock patterns.
