Best ResponseYou've already chosen the best response.3For question 1 and 2, the second player has the winning strategy. For any turn, if Player 1 puts a number in row i, Player 2 needs to put a number in the same row. In each row, make the first three spots group 1, and the second 3 spots group 2. Whichever group Player 1 puts the number in, Player 2 puts his number in the other group. Now, in the odd rows, Player 2 can force the black square to end up in Group 1 since: 1) If player 1 puts numbers in group 1, player 2 responds with smaller numbers in group 2 2) If player 1 puts numbers in group 2, player 2 responds with larger numbers in group 1. In the even rows, do the opposite (switch the words smaller and larger), and this will result in the black squares ending up in group 2. If player 2 plays like this, the only possible way player 1 can win is if the grid looks like this:dw:1335510717037:dwSo to counter this, all player 2 has to do is change his strategy in the sixth row, and make sure the black square doesnt end up in column 2, 3, or 4. to accomplish this task, make group 1 columns 2, 3, and 4, and group 2 columns 1, 5, and 6. If player 2 plays like he did in the other even rows, this will result in his victory.

Best ResponseYou've already chosen the best response.3To be a little more specific about what size numbers player two should be placing, they should be the largest in the row if he's putting a larger number in, and the smallest in the row if hes putting a small number in.
