4. ...Bc5

 * The move that signifies the Traxler Counterattack or sometimes known as the Wilkes-Barre Variation. This can quickly lead to mate with the queen.
 * This bold move ignores White's attack on f7 and can lead to wild play as Black can try a bishop sacrifice on f2 if White plays Nxf7. Instead, White will often prefer Bxf7+.
