O-O - Kupreichik's Variation Having avoided committing the queen to e2 on move 6, White typically puts it there anyway with 7. Qe2. This restricts Black's options, because now ...d5 would self-pin the c6-knight allowing White to capture the e5-pawn for zero compensation. Viktor Kupreichik mixed things up a couple times with 7. O-O. If Black reacts the same way she would after 7. Qe2, with 7...Be7, White has a huge positive score with the plan of Bxc6 and Qe1. But alert Black players found 7...Nd4! to take advantage of the fact that the e-pawn isn't under any pressure.Ruy Lopez
