And who is winning now anyway?
A game almost identical with tic tac toe is played on an \(m\times m\) grid between players A and B.
Like in the classical game the winner is the one who can place 5 Os or Xs but this just on columns or rows diagonals not being included.
If A starts the game, and both players play optimally which of the following statements must be true?
Note that the players win just for consecutive signs on a column or a row and diagonals are not included.
