Is the Captcha always Qf7 ?

For my captcha for posting this was a smothered mate.

Indeed. The question is: f2 or f7?

Sometimes there’s a glitch in the mate-rix: Bishop Thingy delivers checkmate as well.

@Sarg0n Since it takes more energy to move the queen (it's a heavy piece after all), Bxf7# is to be preferred in such a case.

Yeah, I find it more stylish to use the Bishop if possible. Noobs use the Queen usually.

Now you know. :)

nm, I just Qxh7 while submitting this post.

I would like to see a subtle pawn checkmate in there one in a while.

Bxg3#

My captcha for this post is Bxf7#.

From game BDgmcjug.

Bxf7#
Fra2fKgy

However in last time I saw Qg7# and some positions where King is not on ground file

I just got a nice Nd5# Légal's Mate from JfloJp5F. :)

I saw a fool's mate once, and multiple mates using rook and knight as well. All #1's are valid captchas I think.
