After 4. b4, the Evans Gambit, Black has the following:
4... Bxb4
This is by FAR the most common response you will see in your games with it. We will concentrate mostly on this.
4... Bb6
The Evans Gambit declined. This is also a solid variation. The best for White may be 5. a4.
4... d5
The Countergambit Variation. This is extremley rare, and all of the lines are pleasant for White.
Also:
4... Be7
This resembles a tempo up Hungarian Defense for White. It is very very rare, but there is only one path to a not so big advantage for White.
