in this odds game, you will learn how to attack the edge.
(Text moves) 1.G7b 2.P7f 3.K4b 4.B6f
4.B6f threatens Bx9c+
(Text moves) 5.S8b 6.P9f 7.P7d 8.P9e 9.P6d 10.P5f
6.P9f and 8.P9e activate the Lance on 9i.
10.P5f makes room for the Bishop to go to 5g-square if White plays P6e.
10.P9d doesn’t work because 11.Px9d 12.Lx9d 13.P6e 14.B7g 15.P*9c and Black will lose material.
Black wants to keep the Bishop’s diagonal to 9c-square.
(Text moves) 11.K3b 12.P9d 13.Px9d 14.Lx9d
(Text moves) 15.P8d 16. R9h
15.P8d is a poisoned Pawn. if Black plays 16.Bx8d, White’d play 17.G8c(or 17.S8c 18.B9c+ 19.P*9b ) 18.B6b+ 19.Gx9d. 16.L9b+ is possible.
16.R9h is important. don’t let your Rook out of play.
(Text moves) 17.S7c 18.L9b+ 19.S4b 20. +L8a
18.L9a+ is playable and if White plays 19.G8b, Black can play 20.+L9b(20.P*9c is possible)21.G7b(21.G8c 22.+L9c) 22.+L8a
(Text moves) 21.G6c 22.R9b+ 23.P6e 24.B5g 25.K2b 26.P1f 27.G3b 28.P1e
Black is successful with 22.R9b+
26.+L7a is possible. it threatens +L7b S6d +L6b
now you can see that White can’t defend the edge with one Silver, but what if White could defend with 2 defenders? let’s go back to diagram 2
(Text moves) 11.G7c 12.P9d 13.Px9d 14.Lx9d 15.G8d
15.G8d blocks Bishop’s diagonal and threatens to caputure the Lance on 9d
(Text moves) 16.R9h 17.P*9e
17.P*9e: thanks to the Gold on 8d,White can block the Rook.
(Text moves) 18.Bx8d 19.Px8d 20.Rx9e
18.Bx8d: it’s really hard to play even though it’s a book move. some people fail with 18.L9b+ 19.S7c 20.Bx8d 21.Sx8d and Black can’t play Rx9e. the move order is very important here. Black is behind in material but the compensation of Rook promotion is big.
(Text moves) 21.S7c 22.L9c+ 23.S6b 24.+L8c 25.S5a 26.R9b+
9c- Silver escapes and makes himself useful.
(Text moves) 27.G5b 28.+L7c
28.+L7c threatens +L6c
(Text moves) 29.B*5d 30.S3h
29.B*5d threatens Bx2g+ and guards 6c-square
(Text moves) 31.P3d 32.P5e 33.Bx7g 34.G7h
there’re not good moves for White. Black threatens +L6c and G*6f
