Related to [this question][1], where there the solution was unexpected for us.

Let $n,m$ be positive integers, $n \le m \le n^2/2$.

The board is $n \times n$ square grid.

- Two players, $A,B$ make $m$ moves, where at each move each of them
color uncolored vertex of the grid red.

- $A,B$ take moves in turns.

- A move is picking two red vertices and drawing a straight line between them.

- If the line intersects another line or passes through a third red vertex,
the game ends and the player who made the move loses the game. 
Two or more lines are allowed to end at the same vertex.

- If there are no valid moves, the game is draw.

Is there winning strategy depending on $n,m$?

If the general solution is hard fix $m$, say let $m=\lfloor \frac{n^2}{4} \rfloor$
