Promote to bishop?

We just saw a puzzle where a pawn is promoted to a knight.  I remember seeing one where the promotion is to a rook to avoid stalemate.  Does anyone know of a puzzle where the correct promotion is to a bishop?

Yeah, there are a few, it's frequently used as a defenisive thing to create stalemate positions.

Don't go away, I'll see if I can find some....

Ok, her'es one:

The reason you don't see many puzzles where a bishop underpromotion is required compared to knight underpromotion puzzles is because the bishop's movement is not unique while the knight's is (of course the queen can move like a bishop).  Situations where a bishop is required rather than a queen are very rare.  You would only do it to avoid stalemating your opponent I believe.

Here is a great example:

Look again....

1 g8(B)+ RxB 2 hxR(Q)+ and white wins

My favorite...

Of course if white had promoted to a queen, it would be stalemate.

I was looking at yours upside down :p    I'm REALLY tired lol.  Should get off chess.com perhaps..

What are you talking about in post #6?

Everything is wrong with that puzzle.

good one

Without the g2 pawn it wouldn't be so "easy"

1. g8Q+ Kc2 2. Qxb8 Qxb8+ 3. Kg7 Qe5+ 4. Kg8 Qg5+ 5. Kh8 Qg6 6. g4 Qf7 7. g5 Qf8#

post #6 - Why not 1.a8(Q)+ Kf4 2.Bd6+?

good find.

yes, it was a good find.

fine, then... throw some white pawns on the board so that it works :P

I was setting it up from memory

Here is a puzzle where you need to promote to a bishop for a win.  Check the move list to see what would happen if white promoted to a queen.

My favorite examplse of underpromotions are solutions to the so-called "Babson Task."

I had a thread about it here, but I will repost the best of them:

Would this work?
