ITOU selected "Ishida ryu" opening , and AKIYAMA prevent 3. R-7h by 2...K-4b .

The move 3. R-7h makes "Haya Ishida" formation . This formation make Gote difficult to choice "Anaguma " . So many professional shogi player think "Haya Ishida" is good formation .

But "Haya Ishida " has weak point . It is Gote's dropping Bishop at 4e square ; B'4e . The Bishop at 4e can capture a Pawn and promote at either 2e or 6e .

Sente usually replies dropping his Bishop at 7f square . This move prevents the opponent's Bisop promotion at 6g and has a chance to promote 4c square . Gote's move 2...K-4b prevent this promotion . Then Sente can't move 3. R-7h .
