.This is the line from the start to the end with some comments of mine.
Handicap: Other(Special 6pcs handicap)
1. ... K-4b 2.P-7f
*P-7f opened your Bishop's diagonal line. It goes to the square of 3c.
K-3b 3.P-6f P-3d
*P-6f closed your Bihop's diagonal line. This pawn advancement is to trap Hamster in the future.
*The pawn on 6f became floating due to kNight jump to 7g. So Hamster can take it. But this is a trap to activate your Rook.
*Thie horizontal Rook transfer is the answer to Bx6f. You will allow the Bishop get promoted, while your Rook will break through the Hamster's camp with promotion in the next moves.
*Your Rook suceeded in getting promoted. It's a very powerful piece now. Hamster's promoted bishop is trying to take your kNight on 2i.
*This kNight jump of N-6e has two aims such as Nx5c+ and B-1a+. Generally speaking, a move with plural aims is often a good move in shogi. Hamster prevented your Bishop from getting promoted to 1a, but...,
*Hamster will have to move the King since he cannot drop a Pawn on 4b since double pawn is not allowed.
*Checkmate with your major pieces(R & B) getting promoted. Promotion of major pieces is one of the critical ways of winning a shogi game.
