very simple 1.Bb6+ Kxb6 2.c8=N+ Ka5 3.b4#.
1. Bb6+ wins. Took me a while though.
If King moves to the 8th rank:
2. b8=Q mate.
If 1…..KxB
2. b8=N+ Ka5
3. b4#
Cute. 1. Bb6+, Kxb6 2. c8N+, Ka5 3. b4#
1. -, Ka8 2. c8Q/R#
Very cute!
1. Bb6+ …Kxb6
2. c8=N+ …Ka5
3. b4#
seems straightforward
Bb6+ Kxb6
c8=N+ Ka5
b4#
Sac B with check on b6…promote p as knight on c8 …check to king..
zugzwang K to a5…push pawn to b4 mate
White mates in 3 moves
1 Bb6+ Kxb6 ( 1… Ka8 2 c7 c8 = Rook or Queen mate)
2 c7 c8 = Knight Kb6 a5
3 b3b4 mate
Nice
Bb6+

bishop check; followed by pawn promotion with check & mate or mate on the next move.
1.Bb6! Kxb6 (1…Ka8 2.c8Q#) 2.c8N! Ka5 3.b4#
I like this problem, it was funny, I solved it, in this way:
# in 3.
1.Bb6+,K·b6 2.c8=Knight,Ke5 3.b4#
Interesant:)
bishop check;
pawn promotion w/check mates immediately or it’s mate next move
Bg6+ Kxg6 (forced)
c8=N+ Ka4
b4# checkmate
1.Bb6+ Kxb6
2.c8(N)+ Ka5
3.b4 mate!!!
