Impossible Puzzle (Part III)

Sort:
True_Beginner

Hello Gentlemen (and ladies), let me ask you a puzzle which my friend gave this morning. Well my friend knows that I love to solve puzzles which isn't able to be solved by computer engine, the hardest ones. And this is the third I want to ask a help from you.

Well if you follow my previous posts, this is a continuation from before. I named it "Impossible Puzzles" because it can't be solved by "common" computer engine (for it contains more than 16 pieces on one side), but it's "solvable" still.

I'm still stuck with it. White to mate, in three.

I'm thinking to give a trophy to him/her who can help me.

Thanks and regards.

Ne5 Be7, Rb8 if Kg7 what is next

@DrPsycotic and @sea-biscuit: Please specify which knight or bishop you mean, because there are two pieces that can occupy Be8 and Ne5.

@BorgQueen: Yes you're right, puzzles don't have to be always occured in real game. Not to mention that Balck have still chances, to draw.

True_Beginner

I agree with @bays_al.

Black has a "useful" bishop that can block Ra7 control for the King to escape via g7.

DrPsychotic

bishop on h5 to e8, then black bishop to d6, bishop on h7 to g8+, then Black bishop exchanges rook on H2, then queen to h3#

or else....

hBe8 Bd6, hBg8+  Bxh2, Qh3+

You can mate Black in 2 moves:

1. Nd3-f4  Bxy

2. Nf4-g6#

True_Beginner

@DrPsycotic: How if B5e8 be answered by Bh6?

@custimoz: How if Nf4 be answered by Be7?

bays_al

1. B5g6 - Bd6( for capturing checker rook)

2. Bg8+ - Bxh2

3. Qh3#

 

second line

1. B5g6 - Bg7

2. Bg8+ - Bh6

3. Rxh6#

third line

1. B5g6 - Bh6

2. Rb8+ - Bf8

3.Rxf8#

with rest black bishop moves checkmate in two moves

sea-biscuit

1) Nd3 Ne5 -> Be7
   Qd1 Qd8 -> Bd8
   Ne5 Ng6 -> Mate

2) Nd3 Ne5 -> Ba3
    Qd1 Qd8 -> Bf8
    QxB -> Mate

3) Nd3 Ne5 -> Bg7
    Qd1 Qd8 -> Bf8
    QxB -> Mate

DrPsychotic

How about B5g6  Bh6, Rb8+ BF8,B7f8#

custimoz

Right, didn't notice Be7.

But still, there are many solutions to mate in 3.

1. Nf4  Be7

2. Rb8+ Bf8(Bd8)

3. Ng6# or Rxf8/d8#

bays_al

1) Nd3 Ne5 -> Be7
   Qd1 Qd8 ->Bd8 (why Bd8 this not only move if Kg7?)

bays_al

after black's Be7 move Black is preparing g7 for King

sea-biscuit

4) Nd3 Ne5 -> Be7
    Qd1Qd8 -> Kg7
    QxBe7 -> Kh6
    Qe3 -> Mate

True_Beginner

I think B6g6 is refuted by Be8, again King escapes via g7.

1) Nd3 Ne5 -> Be7
   Qd1 Qd8 -> Bd8 (How if Kg7)?
   Ne5 Ng6 -> Mate

White cannot checkmate in the one remaing move.

True_Beginner

@custimoz

1. Nf4 Be8

2. Rb8+ Kg7

failed.
