Cooper's Hex

A variant of Hex or of Y, where move order is changed from the ordinary alteration of Black and White (BWBWBWBW...) to a system where each player sometimes gets two moves (BWWBWBBWWBBWBWWBW...). The sequence is given by the odd-even parity of the sum of the binary digits of the natural numbers:

Early reports indicate that in strategy, the game is somewhat similar to Halsør's Hex, where each player has two moves after Black's first move.
