Ruy Lopez, Barendregt Variation[edit]

Nxe5 is now threatened, as if Qd4? Nf3 Qxe5?? Re1 the queen is lost. At this point, there are several moves, for example Bg4, Bd6, f6 and Qd6. Bg4 is the most aggressive, pinning the knight, while the supporting Bd6 is also good. f6 looks ugly, but is playable now that white's light squared bishop is off the board.
