5. b3 e5!?, clamping down on the d4 square. It is not much of a pawn, but then again White does not have much in the way of compensation either. 6. Bb2 Nc6 7. Nf3 e4 8. Ng5 f5 9. Qh5+? does not work, 9...g6 10. Qh4 e5 is winning. 8. Ne5 Nxe5 9. Bxe5 Bf5 10. Nc3 f6 driving back the bishop; Black's light squared bishop easily protects his king. 11. Bf4 better then getting the bishop stuck on g3, 11...e5 12. Be3 Bg6, Black's extra pawn is alive and he has a grip on both d3 and d4.
In summary, Black should try clamping down on the d4 square. White's backward d pawn is not an inconsiderable positional feature.
I have been facing some difficulties against Alekhine Defence and I would like to have everyone's opinion on this opening idea. It looks unsound just tell me how much unsound is it and how can this continue. Something to improve chess understanding indirectly instead of just memorising moves.
The idea is black's structure is difficult to develop peices. The e6 pawn blocks e7 pawn which blocks f8 bishop which in turn block h8 rook.
On the otherhand white isnt really well developed either but I think it will be easier for white to get his peices out before Black.
Black does have option to play g6 Bg7 but white can easily stop it.
Moreover in a few games I have tried it in white's pawns on queenside become very useful if Black tries to castle queenside. Tell me your analyses.....
