Quote:Returning to this thread, and inspired by the thread on underrated Alekhine lines - after 5. dxe5 Bg4 6 Be2 Nc6 (as given by SDO apparently and also as in Pinter-Palliser). Both SDO and Pinter went for c4 ideas, but 7 c3 is the position in the Kupreichik game from the other thread, arising from the 4 Be2 line. This is - IMHO - quite annoying for Black. I must say that it's not so clear to me at all how Black ought to meet 5 dxe5. I do wonder if it's really a bad move after all, although it looks as though it ought to be, somehow.
Well, it is fairly clear to me how Black should meet 5. dxe5. He must play on the basis that White's e5 pawn is weak: 5...Bg4 6. Be2 and now, in my view, 6...e6 is significantly more flexible than 6...Nc6.
A key theme for Black is to bring his d5 knight to g6 via e7, for example, 7. Qd4 Bxf3 8. Bxf3 c6 9. O-O (9. Nd2 Qb6) 9...Nd7 10. c4 Ne7! =+. This is analogous to 5...Bg4 6. Be2 c6, a line discussed at some length in Burgess's "The Complete Alekhine."
For another example, 7. O-O Nd7 (Black wants to be able to play ...c6 so that his queen can attack White's e-pawn) 8. c4 Ne7! and Black meets both 9. Bg5 and 9. Qb3 with 9...Qb8!. It may be equal, but Black has play for a win.
7. c4 Nb4 is fine for Black.
