The 2nd and 3rd Level

[ckff93]

To be overly diplomatic...

You are trying to think at 2nd and 3rd levels and therefore there is one person doing it in the game you are playing, so probably there is more than one person. So in essence, it really comes down to the specific opponent you are playing. However, if you are only playing for money (not to get better overall) I would say it is not worth your time because you'll probably over think your moves and create more leakes in your game.
