Alan Tate Wrote: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.
Not quite following your analysis here Alan :/ 7.Ng5 has been seen a few times before, including a game Bogoljubov-Alekhine apparently. I thought I remembered some Hebden games as white here but can't find them now.
Anyway, 7.Ng5 e6 8.a4 doesn't force 8...b4 ( a bad move for the reasons you give) but he rather has several other decent moves. The main line waa actually 7.a4 instead of 7.Ng5
Just spotted your update so ignore this if you like
