Can a king mate a king?


whats the difference between check and checkmate?

Also, can I play a game against someone? I feel confident in my chess skills now that I know a king cannot mate a king. (My friend and I spent an hour trying to mate each other with two kings on the board - I think I had a slight edge though because his king was in the corner - but irrespective, I think I could probably beat someone rated 2000 (or maybe 3000) now)


ok. Thanks so much!

Most girls I know IRL (the graphics stink) can pick up the basic concept of checkmate but not the basic concept of paying for the check

My goodness this smells bad. Two players who have pretty much new accounts on chess.com and they actually stumble into fools mate? At least it's polite trolling.

Also @xwoodfin said that I got checkmated in the quickest possible fashion. That got me thinking, how many checkmates are there?

Also, how do you know my opponent was new to Chess.com? He probably wasn't (since he was really good)
A king cannot mate a king unless it moves out of the way of another piece, freeing it up to checkmate the king, like in the following example:

By the depth of your questions, you could probably beat a 3500 player. The fact you knew what those ratings mean, but didn't know the difference between check and checkmate indicates a very high level of understanding. To answer your other questions, which only a 3000 rated player would not know yet, how many checkmates are there? 7, but only 6 have ever been achieved. Can a king mate a king? Yes. Just not in chess. It is 2018 afterall.
