## Checkpoint 2 Notes

### TTT Strategy

For each of the following board states, if you are playing as X
and it's your turn, which action would you take? Why?

   | O | O       |   | O      x | X |       X | O |   
---+---+---   ---+---+---   ---+---+---   ---+---+---
 X | X | x        | X |x       X | O | O      | x |   
---+---+---   ---+---+---   ---+---+---   ---+---+---
   |   |         |   | O       |   |         |   |   

   For #1, choosing 6 wins the game For # 2 choosing 6 blocks 0 from winning.
   For #3 choosing 0 gives a win on the next turn regardless of where 0 blocks.
   For #4 choosing 4 means 0 has block, then if x chooses 6 then win in 2 or 3.

### Initial game state

You can get the inital game state using game.get_initial_state(). 
What is the current and future reward for this state? What does this mean? 

I think 0 menas the game is fair, 1 is more x wins a negative is more o wins.
