There are players who are famous for their comeback ability. I think you are one of them. You've heard the comments. The difference between the player who can come back, and the player who flounders under the attack is found in the Will Skills. If you have strong fully developed Will Skills, you will automatically fight to the finish.
Good things happen to people who are motivated to win.
You can never play more than one game. So the match deficit does not enter into how you are going to play this match. Use your will skills to win a few games, make a few shots, play a few safeties. Play for respect. Get his attention.
