Bird’s Defense could be an appealing option if you wish to steer clear of theoretical lines early in the Ruy Lopéz Opening. By playing Bird’s Defense, Black sacrifices the defense of e5 and instead launches a counter-attack by threatening the bishop. However, a possible downside is that after the exchange of knights on d4, Black’s pawn structure might become slightly inferior, despite the slight advantage in terms of space.
1. e4 e5 2. ♘f3 ♞c6 3. ♗b5 ♞d4!?
Bla bla, what traps await White in that direction?
