White to move and checkmate in 5.
8/BB6/8/8/6p1/6Kb/6p1/7k w – – 0 1
1)Kf2 Kh2 2)Bb8+ Kh1 3)Bf4 g3 4)Bxg3 Bg4 5)Bxg2#
You want to prevent stalemate and force the black bishop to move , protecting g2 pawn.
King should not go too far for a walk though 🙂
1.Kf2 Kh2
(if 1. .. g3+ ,
2.Kxg3 Bg4 3.Bxg2# )
2.Bb8+ Kh1
(if 2. ..g3+,
3.Bxg3+ Kh1
4.Bf3 Bg4
5.Bxg2# )
3.Bf4(waiting )g3+
4.Bxg3 Bg4
5.Bxg2#
This is rather easy.
It is needed to make black play g3 so his bishop can escape (and leave protection of g2).
We need Bb8+ as a possibility without black K escaping via g1. So we can exclude Kh4? and instead play:
1. Kf2! Kh2 (1. … g3+? 2. Kxg3 zz B move 3. Bxg2#)
2. Bb8+
A)
2. … Kh1
3. Bc6/Bd5/Be4/Bc7/Bd6/Be5/Bf4 (zz) g3+
4. Bxg3 (zz) B any
5. Bxg2#
B)
2. … g3+
3. Bxg3+ Kh1
4. Bc6/Bd5/Be4/Bc7/Bd6/Be5/Bf4 (zz) B any
5. Bxg2#
1.Kf2 Kh2
2.Bb8+ g3
3.Bxg3+ Kh1
4.Bc7 any B move
5.Bxg2#
All smooth work.No need to think.
1.Kf2 Kh2 2.Bb8+ Kh1 3.Bc7 g3+ 4.Bxg3 and 5.Bxg2 mate
Kf2 kh2
Bb1 kh1
Bc2 G3
Bxg3 B moves out
Bxg2#
1.Kf2 Kh2
(1…g3+ 2.Kxg3 B any 3.Bxg2#)
2.Bb8+ g3+
(2..Kh1 3.Bg3! B any 4.Bxg2#)
3.Bxg3+ Kh1
4.Bf3 (or any move along h1-a8 diagonal) B any
5.Bxg2#
