# Large Tic Tac Toe Tactics Number 1

Logic Level 4

You're playing a large Tic Tac Toe, with 5 in a row to win. It's your turn as $$\color{blue} O$$.

Let $$A$$ denote the least number of moves (for you to make) to win.

Let $$B$$ denote the number of possible initial point(s) (for you to make) such that you can win in $$A$$ moves.

Find the value of $$10B + A$$.

Assume the player $$\color{red} X$$ makes all the best possible moves to stay in the game (for as long as possible).
