How to get killer king award??
You can also get this achievement by castling checkmate; this counts as a king move even though the rook is the piece doing the checkmating.
I did It against a bot (Martin) but it is not showing. Why? may I know the cause?
It is generally only possible if your opponent blunders very badly. Best to get it before your elo gets too high!
Here's an example of how to do it (my opponent had played ...Qxe7??, taking a knight):

That's a very bizarre thing to say.

I know it is. But from what I've seen, it does only seem to happen if your opponent (pun not intended) royally screws up. Your king usually has to be in grave danger, so your opponent will have to blunder an attack.
A checkmate by castling is also very rare (there's an achievement for that too, even though it also counts for "Killer King") for the same reason.
This is why I believe that, barring unbelievable screw-ups, this achievement is only possible if it's allowed on purpose.

This is absolutely not true. All you need to do is find an opponent who doesn't resign, take all their pieces, get two queens (or rooks), set up the discovered mate and do it.
I'd bet that this is how 99 percent of people get the award, and the crazy unlikely way you described is 1%.
