Checkmate by Castling

Has anyone done this? Do you have any good (fun) examples to share?

That is such a cool way to win.

Indeed I have. Granted, I greatly benefited from a ratings mismatch, but a fun mate non the less.

I should mention that I saw I had quicker mates in that game but once all his pieces were gone, I tried to get the castle mate

Not yet

how about this game, in under 20 moves,  between 2 Masters --  the King moves up ( he could have castled Q-side with same result ) delivering checkmate.

I've never even thought of this, but this looks like such a cool way to mate someone

haha... that's awesome !!

Thanks for sharing -- I see you were playing for it. Chased the King on to your back rank.

I read about the hidden "Achievement" for checkmate by castling and got curious. There's also a discovered checkmate with the king, slighly different but equally satisfying.

Q_x_B can you give an example ?

I just found this page -- lots of good examples.

Some fun checkmates to deliver, which happens very rarely in actual games:

- Smothered mate with a knight. (Your knight is the only one of your pieces participating in the checkmate. The opposing king is stopped from moving by pieces of his own side. You get only half the achievement if one of the opponent's pieces could capture the knight if it weren't hard-pinned (because in this case you have another piece that's technically speaking participating in the checkmate).)

- Delivering the checkmate with a pawn. (Not a promoted pawn, but the pawn itself, on ranks 3-7, checks the opponent's king, and it's checkmate.)

- Delivering a discovered checkmate. Double points if what you moved was your king.

- Delivering checkmate by moving your pawn to the 8th rank and promoting it to a knight. (Whether it's the knight itself that's delivering the check, or whether it's just a discovered mate... it doesn't really matter. It's cool either way. Maybe if it's the knight itself that's delivering the check it's a bit cooler because it's so incredibly rare.)

Castle mates, underpromotion mates and en passant mates are so cool...

that Paul Morphy vs. Alonzo Morphy game is so cool

It looks like his opponent didn't actually notice that castling was still an option.

This has bothered me every time I've seen this famous game: Why didn't Lasker castle instead of moving his king??

(Fun fact: Lasker lost this game... the king went to the other side of the board! No one respected Bongcloud rules back then."

what are Bongcloud rules ?
