We all know that the straight line is fast. We also know that curve can cover more area. If your opponent uses jab, cross combo at you, all you need is to
- Move your back leg to spin your body to be outside of his striking path.
- Use a 45 degree downward "haymaker" in front of you.
- If your opponent moves in slow, your haymaker may knock his jab and cross down.
- If your opponent moves in fast, your haymaker may knock on the back of his head and drop him.
Here are some short clips for "haymaker". I won't call it "hook punch" because the striking area may be your forearm instead of your fist.
