Ruy Lopez Main Line
Black chose not to capture Whites e-pawn on the previous move, but the threat still hangs over Whites head. White typically removes it with 6. Re1. Either 6. Nc3 or 6. d3 would again interfere with Whites optimal plan of c3 and d4 (compare the position before 5. O-O).
White can also opt for the fantastically named Delayed Exchange Ruy Lopez Deferred 6. Bxc6!? (deferred with 4. Ba4 and delayed with 5. O-O, or something like that). Compared to the main line of the Exchange Variation, White has wasted a move but Black cannot immediately play ...f6 to hold the e-pawn. In addition, Black's bishop on e7 has been prematurely developed compared to the normal Exchange Variation and is misplaced.
A very offbeat system is the Worrall Attack, 6. Qe2, planning to hold e4 with the queen and move the rook to d1 in preparation for d2-d4, but the reason this is not played more often is that it takes too much time.
