The fastest way to recover and stand back up after getting knocked down is by tapping the screen with as many fingers as you can at the same time.
A good combination attack: one dodge, one hook, one uppercut. Use the one dodge in the same direction that your opponent is swinging from to set up the attack, then hit him with the hook.
Want more gold or experience points!? You can earn far more gold losing on the amateur circuit than winning on arcade mode, because the amateur circuit pays out slightly more for losing than arcade mode does for winning, combined with how quickly the fights go by when you start them with almost no energy.
When you play through the amateur round tournament, the game progresses whether you win or lose, and even if you don’t win a trophy, you will win a large amount of gold just for competing. Go for one entire competition round in the tournament without recovering, letting yourself lose, so that you can build up a ton of money to use on recovery treatments.
