In many  games  of  GoteSaken  Bisha ,  Sente  pushes  the  2nd  file  Pawn  with  P-2e , just  after  Gote's  R-3b  , to  disturb  a natural  development  of  ISHIDA  ryu  hongumi.

After  the King  moved  beside the Bishop , Sente  has  a  choice . Whether  he  starts  making  Ibisha  Anaguma soon  or  not .

(diagram 4)

Sente pushes  the 3rd  file  Pawn . This  Pawn  has  some  meaning  ; (i) attack  with  P-3e , (ii)opne the way  of  2i-Knight , (iii) open  the path of  4h-Silver . These lines  all  belong  to Kyusenstrategy .

The main  idea  of  Kyusen against  Gote Sanken  Bisha  is  ," Without  Gote's  3c-bishop  ,  Sentecan  easily  break  the 2nd  file  of  Gote's campby Sente's  Rook " .  

To  remove  the 3c-Bishop , 2  ideas  are  exist .The  1st  one  is  directly  pushing  the  4th file  Pawn  with  P-4e  from  Sente  to reopen  Gote's  Bishop  line  . After  Gote reopens  the Bishop  line  , Sente  can  remove  the 3c Bishop  by  exchanging  it .

The  2nd  idea  is  threatning  the  3c-Bishop's  head  by  Sente's  Silver  to  advance  4f  square ,and  Sente forces  Gote  to  exchange  Bishops .

Sente advances  the  4th  file  Pawn  to attack  in  this  file . Replying  Sente's  Knight  jump  ,  Gote  must  move  his  Rook  in 2b  to  avoid  losing  an  advantage .  This  attacking   strategy  is  called  Yon-Go  Fu  Hayajikake.
