There are only \(O\)s on the board.

Logic Level 3

\[\begin{array}{|l|c|r|}\hline O & O & O \\ \hline O & O & O \\ \hline O& O & O \\ \hline \end{array}\]

  • There are 9 \(O\)s on the board.
  • Two players take turns to play.
  • Each player needs to choose a row or column(no diagonals) and take away 1 to 3 of the \(O\)s in that row or column.
  • The player who takes away the last \(O\) on the board wins.

Assume that the two players play optimally,then who will definitely win?
