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.
