In this time , Sente tries to make a promoted Bishop with B*6e after Bishop exchange , because Sente can't break Gote's 2nd file .
(see former contents ; Niteme San-Ni Hi senpou , part 1. )
after diagram 1
In the diagram 2 Gote can't protect both 8c and 4c Pawns , and Sente can promote the Bishop . So Sente seemes to get advantage . How Gote should play ?
after diagram 2
Gote drops a Bishop , he protects 8c file and he also aims to make promote his Bishop in 4th file with Bx4g+ .
Sente can select one of 2 lines ;
(1) Sente exchanges the Bishops again with Bx7d .
(2)Sente makes promoted Bishop with Bx4c+ .
Both lines have difficult variations .
