3.P-2e  K-6b
(diagram 2)

 6.Sx8h   B*3c  
 7.R-2h   P*2f  
 8.N-7g   R-2b  
 9.S-3h  
(diagram 3)

Sente  tries   to  break  Gote's  Bishop  head  with  4.P-2d . After the Pawn exchange , Gote  exchanges  the Bishops  and  drops  his Bishop  with 6...B*3c . This Bishop  dropping  is  forking  2d-Rook  and  8h-Sivler .

To proct  both  2d-Rook  and  8h-Silver , Sente's  Rook  backs  to 2h . Gote  drops  a  Pawn  on  2f .If  Sente  captures  this  Pawn  with  8.Rx2f  ,  the8h-Silver  is  captured  by  Gote's  3c-Bishop  for  free  .  

Sente's  8.N-7g  blocks  Gote's  Bishop line . Gote's  Rook  comes  to  2b . Sente  should  protect  the 2nd  file  to  decline  Gote's Pawn promotion ; P-2g+ . So Sente  moves  up  the right Sivler  with  9.S-3h .

Unitl  the  diagram 3 , Gote gets  an  advantage .Because  Sente's  3h Silver  is  difficult  to  use  effecitively  and  Sente's  Kakoi  is  difficult  to  build .
