=Morphy Defence= Black has taken back the initiative and has to make an important strategic choice.


 * The most intuitive way to go on is to put pressure on the e4 pawn with /5...Nf6/ or /5...Bb7/.
 * If Black really wants to get rid of the white bishop, he can try the Norwegian Defence /5...Na5/, a line that can become very sharp if White tries the Bxf7+ sacrifice.
 * Another classical way to go on is /5...Bc5/.
