thinking you will lose to your enemy this Fri is not. Past games not equal Friday game. Unless u make the same moves and mistakes with him.There must be some areas you need to improve or change to improve the odds with him. Just looking at the end results alone would let us miss out the keys to our potentially fast improvement.
My mentor say unless obvious or when your enemy has won the game, the result in still uncertain, so don't declare yourself as the loser first.
