Kings Indian Defence - Ne7???

Sort:
RJL12


 I've been trying to reduce the uncertainty I normally feel when faced with the multitude of possible opening moves by starting to read up, rightly or wrongly, on a standard opening on the web - http://en.wikipedia.org/wiki/King's_Indian_Defense
 
Reading through the first few moves, I can see the logic to them upto black's move 8 on the classical continuation:-
 
The Main Line or Mar del Plata variation continues 7.0-0 Nc6 8.d5 Ne7 
 
I might be missing something obvious but can anyone explain what advantage Ne7 gives to black ??

Ne7 is well worth its weight in gold.  the e-pawn is now more solid thanks to d5, and now Black has more strength at f5.  Maybe you ought to study a few games and see how the masters played with Ne7 to understand their thoughts...Sometimes its hard to see a checkmate from move eight.
