How many checkmates can you find in this impossible (but hilarious) position?

There are more than 14 if you consider promoting a pawn to a rook instead of a queen a different mate.

Well, there are 20 mates IN ONE.

As to how many checkmates there are, no length specified (as in the original question) well, some incredibly large number :)

I found 69.

ehhh...ehhhhhh....QD5........F@*# STALEMATE >_<

What I meant was checkmates in ONE!

20th mate(easiest) could be done by Ke5 Kxe7 Qe6

I found 19 confirmed but thought I had found 20 the first time I did it. Spent about a minute on it for 3 passes. You can pick up additional mates changing promotion from Queen to Rook.

Very Enjoyable!

Thanks for doing that - well done!!!
Cheers

Unless we count promotion to rook rather than to queen as a separate move, I only see 15 mates in one. I wonder what I am missing.

I got 20.

5 from promoting 7th rank pawns to queens,
5 from promoting 7th rank pawns to rooks,
2 from pushing 6th rank pawns,
2 from the bishop, and
3 from each queen.

Qgb5# was a harder one :)

I also found 20.
