Don't mate in one!

Logic Level 3

What move can white make and not mate in one?

Now, to convert your answer to a number:

Let $C_1$ be the column you are moving from and $R_1$ be the row you are moving from. And, let $C_2$ be the column you are moving to and $R_2$ be the row you are moving to. (Rows 1-8 and columns 1-8) Finally, concatenate your answer as $C_1$ $R_1$ $C_2$ $R_2$

For example, if you were to take black's pawn with your rook, you'd put your answer as 7675.

This is not an original problem. I believe the original author was Karl Fabel.

The answer is 7636.

If you move $\boxed{7636}$ this allows black to get out of the mate by taking your bishop with his rook. Bonus points if you noticed that this is an impossible position, as both of white's bishops are on white spaces! (Unless a pawn was promoted to a bishop :0) )

Yeah two white bishops. Most likely the a 'file' pawn was under promoted to a white bishop? And why would the black king march into enemy pawn fortress? and the white king setup castle in the enemy territory? Too many impossibilities. Great puzzle though, thanks for spotting and posting it here.

Since the underpromotion is not impossible, as well as the king march, the position is still valid.

I definitely saw the puzzle before. Nice one!

this is a... weird position this probably won't happen in any game. and who wants to NOT mate in 1?
