Hey man here r some tips.
1. Keep ur teeth clenched when in a fight. A hit to the jaw will hurt like hell if ur jaw is loose.
2. Never loose eye contact, unless if there is more than one guy.
3. Don't commit to far into a fake, it will give ur opponent a clear shot while u retract.
4. Bend ur knees, hands up ready to punch.
5. keep front foot flat for balance, and back foot on toes for power.
6. Back foot should be ur superior side, font foot should be ur inferior side.
7. Lean a little foward. Not to much to where there is stress on ur neck or back.
8. If ur going for a KO, or a quick fight, Go for the cheek/side of the nose. The cheek for the knock out, and the nose for a fail safe. (when hit in the nose, they're distracted, their balance is off, and their arms arent ready to deflect a full force hit.)
9. Never wrap him with out wraping his arms too.
10. The best way to dodge is to move ur head back and toward the direction in wich the punch came from. When u have dodged a punch, take a quick offensive. When doing this u want to puch with the arm that matches his superior foot. not his right ur right. If his right foot is back, go low with the head while moving forward to ur right and puching his head with ur left hand.
11. If ur punch was just dodged, expect him to catch you off guard and throw a jab or power ounch at u.(or a fake, bewear of fakes.)
12. Never hesitate.
The rest is mostley commonsence. Good luck to ya man.
