St. George Defence/Three Pawns Attack

[edit | edit source]

In this position, the pawn cannot take the knight as 6. Qxb7 would be deadly. Two options are offered to black according to the former author, but only one is alright:

5...Ra7 protects the bishop, allowing the pawn to take the knight, but hangs the pawn. Therefore, 5...Ra7 is out.
5...Nc6 is a good move, defending the b pawn and attacking the now undefended d pawn.
