I'm trying to understand Lothian - Berry. The position exists with a Black pawn on c6 instead of a6 but in this position there are tactical possibilities based around the fact that White may have Nxd5 and e6 and also along the h1 - a8 diagonal. For instance if Black plays 7 ... e6 8. Qf3 Qd7 Black can not play ... h6 next move because this would allow Nxd5, e6 and Qh5+. However when the Black bishop comes to b7 it will be a strong piece so White should play forcefully. 8. a4 seems to force ... b4 but that allows 9. Nxd5 ed5 10. Bxc4! due to the pin. So I don't know what Black should play.
