a Shogi game consists of 3 phases, the opening, the middle game, and the end game.
the Opening
it’s like preparation time to go to war. both sides get Kings castled and develop their pieces to commit to which opening strategies they play before launching an attack.
the Middle game
it’s like a full-scale battle. roughly, when there are piece crashes, or a side sacrifice a Pawn to start attacking, we enter a middle game. there are many trades. you want to maneuver pieces and try to weaken your opponent’s defense.
the End game
the last battle. you try to destroy your opponent’s castle and start calculating to checkmate the enemy King.
82.Gx6a: White’s king safety is secure now but losing the promoted Rook is a big downside for White.

84.S*7b: White can gain a tempo with 84.S*5b but after 85.+Rx1a, White has no much move to play.
85.P*4d: basic pawn tactic. Black doesn’t need to be in a hurry to attack the White King because White has no material to attack.
86.B*6i: tries to attack the Black King because White has no good defensive move.
