ok

nice straightfoward puzzle, no queen sacrifice'. and a realistic position

nice!

cool cool cool

What is the problem with the Queen promotion? No stalemate due to biship and pawn moves for black. Mate  in a couple? Or is it just for the fact of underpromotion?

 Never mind!!! Be6+ was explained by slowhare.

Good.

Everyone is saying "nice puzzle." So what's nice about it? Its just foolish to me to upgrade to a knight when you could just easily upgrade to a queen.

Could have been:

1. c7 1... fxg4+ 2. Kg3 2... Bc4 3. c8=Q 3...Be6 4. Qb7#

 how is that a solved puzzle black king can still move

nice puzzle

cant the king capture the pon?

white checkmates in 4 moves

Interesting.

I like it, and looks like a good way to take out the bishop on the next move.

WHta is tis

HEre we go again....WHERE'S THE FOLLOW UP? It is NOT intutively OBVIOUS! Play it THROUGH!!!

Underpromotion is fun

Interesting, I never thought of promoting it to a knight.
