promotion: why bishop/rook?

PROMOTION:

• QUEEN
• KNIGHT
• BISHOP
• ROOK

1. why bishop?
2. why rook?

Phil_A_S,

  beautiful example

I'm curious of an exampled bishop circumstance

If someone else can fill in a variation where you underpromote to a bishop, please do. I can think of a reason(stalemate) as in where you are forced to promote to a diagonal piece, but cannot promote to a queen. Or the style reason. It's more fun to mate with underpromotion to a bishop than promotion to a queen.

Eebster coming with the Yarosh diagram in 5...4...3...

The one where you go for stalemate by underpromotion yourself?
