In response to your message i would like to say after 12. d6 f6 13. Be3.  I don't think black can win the pawn that easily.  White can protect the pawn with Rd1 and other moves as well.  In some cases the advanced pawn can put pressure on black.  Anyway, i expected this kind of reply.  The move does look dubious and it does look like black could win the pawn.  However, the only thing I am trying to say is that in practice the pawn isn't so easy to win, and occasionly the advanced pawn can put pressure on black.  Also, black almost certainly won't be prepared for this move.

Hi, lately I have been employing a new move in the KID which i belive is a TN.  After 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 0-0 5. Nf3 d6 6. Be2 e5 7. dxe5 dxe5 8. Qxd8 Rxd8 9. Bg5 Re8 10. Nd5 Nxd5 11. cxd5 c6. 12. d6!  Normally white continues 12. Bc4 cxd5 13. Bxd5 and then black can choose from Na6, Nc6, Nd7.  However, I believe the move 12. d6! is just as good, if not better.  my comp rates this position as +.3 for white, and I have had much success with this line in practice. I feel there is compensation for the deeply IQP(12. d6! h6 13. Be7 Be6 14 0-0, Rc1 Rd1 ect.). Also, there are 0 games with the move 12. d6 in my database.  Is that because no one thought of the move before or because everyone dismissed it?   
I would really appreciate your comments. 
Has anyone played this line from either side?   
Have I created a great TN or am I out of my mind?
