omg i just now learn the sickest checkmate ever from chess.com lessons

Arabian mate, Anastasia's mate, Blackburne's mate, these checkmates are so insane. teamwork of bishops knights and rooks, with amazing queen sacrifice... i wish i could get the opportunity to learn more, but at least such things don't happen. rip seeing these 3 checkmating ideas does put a smile on my face at least

Yes, but a lone Knight checkmate via "Smothered Mate" is the coolest of them all

is that with the 2 knights?? and a king

No. Checkmate with 2 Knights alone with a King and no pawns/other pieces on the board can't be forced. Smothered Checkmate is when the enemy King is boxed in by its own forces (smothered) and a Knight delivers checkmate by itself. It is really rare, but aesthetically pretty when it happens

oh like the classic queen sacifrice that leads to checkmate with just the knight... like this

Yeah, that is one example of "smothered mate" and as @TakeThisPawn says, you can learn these patterns online for free. I'm sure there are probably also books/articles that discuss them too.

Here is a solid list that is more than most people know by name:

(actually, memorizing the names can be helpful - but not necessary. What is important is being able to recognize these patterns in your own chess games)

A smothered mate is shown towards the end of this video (time 31:31). This video is excellent for beginning players and I highly recommend it. It is presented by GM Yasser Seriawan and tells some funny stories about some of his earliest games when he was 12; 7 years later he was a GM! Audio gets better a few minutes in. There are 7 or 8 great mating positions covered - all played by beginning players.

PS Simple tips to improve at 35:06 (end of the video).

so i'm losing because of pattern recognition and making same mistakes... or not paying to much attention... rip
