We have a grid of dots m x n, where m is the number of rows and n the number of columns, where m≠n and m, n >2.

.......

.......

.......

.......

.......

.......

Two players alternate turns and choose one dot from the grid and then pick all dots above and to the right of these dots. The purpose of the game is to force your opponent take the last dot.

Do I play first or second? What is the strategy to win?

(for example I chose the 4th dot of the 3rd row from the bottom, so I got all 16 dots above and to the right of this one).

Hi anna_gg

The 3rd row doesn't have a 4th dot.

The grid is initially as at the top of my post. Then after removing the dots, is like it shows below the text. Sorry, I don't know how to do the graphic!!
