Bxc6 Exchange Variation]] =Morphy Defence= By far the most commonly played Black third move in the Ruy Lopez game is the Morphy Defence 3.a6 which puts the question to the white bishop. Although 3.a6 was known earlier it became popular after it was played by world champion Paul Morphy. White has only two good options [[4. Bxc6]] or [[4. Ba4]]. The main point to 3.a6 is that after the common retreat 4.Ba4 Black will have the possibility of breaking the pin on his queen knight by playing .b5. In fact White must take some care to not fall into the Noah s Ark Trap in which Black traps White s king bishop on the b3 square with a .a6 .b5 and .c4 pawn advance on the queenside. =Common Moves= Col begin uto loatright Col 3 Chess diagram rd bd qd kd bd nd rd pd pd pd pd pd pd pd nd pd bl pl nl pl pl pl pl pl pl pl rl nl bl ql kl rl 4.Ba4 (Morphy s Defence Main Line) Col 3 Chess diagram rd bd qd kd bd nd rd pd pd pd pd pd pd pd bl pd pl nl pl pl pl pl pl pl pl rl nl bl ql kl rl 4.
