How to get Killer King

As you already know, there are five different types of achievements that start with Killer. There is Killer Pawn, Killer Knight, Killer Bishop, Killer Rook, and Killer Queen.

But there is a secret 🔑 sixth achievement, known as Killer King. I know you're like "pfft, there is no such thing", well there is.

We already know that you can't deliver a direct checkmate with the king, but you CAN do a discovered checkmate by moving the king out of the way, revealing the checkmate. 

Note: Don't bother playing a bot to get this achievement because we all generally know, we don't get achievements playing with bots. It needs to be with a real human.

It is extremely rare. 

Look at this game where I'm black and get this achievement using a discovered ladder mate
