Tic Tac Toe

Does /prog/ know an efficient algorithm to check for a win/loss/draw in the game of Tic Tac Toe?

Let board be an array of integers where same numbers represent same players or blank, e.g. -1 and 1 for the players and 0 for blank.

Is there a more efficient alternative than checking it like this:
// check if player "1" won:
if ((board[0] == 1 && board[1] == 1 && board[2] == 1)
 || (board[3] == 1 && board[4] == 1 && board[5] == 1)
 || (board[6] == 1 && board[7] == 1 && board[8] == 1)
 || (board[0] == 1 && board[3] == 1 && board[6] == 1)
 || (board[1] == 1 && board[4] == 1 && board[7] == 1)
 || (board[2] == 1 && board[5] == 1 && board[8] == 1)
 || (board[0] == 1 && board[4] == 1 && board[8] == 1)
 || (board[2] == 1 && board[4] == 1 && board[6] == 1)) {
    // player "1" won
}

This is ucking fugly.

and ten extra math and assignment procedures. plus, there's a bug in your code.
