After both players opened the Bishop line with 1.P-7f P-3d , KUMASAKA moved up the King with 2.K-6h . This move has a meaning to decline Gote's Gokigen Nakabisha with 2...P-5d . If Gote still tried to select Gokigen Nakbaisha with 2...P-5d , Sente would get an advantage by making a promoted Bishop . (more detail , please see my blog ; Yamajunn's Shogi opening trasps )
