"Never resign."

my idea on resigning is more mental focused: it doesn't matter what helps you win this game it only matters what helps you blunder less. I find there is an effect that if I play through a blundered position I am more likely to blunder next game because my mental state is blundering is okay. I think this might depend on the person though. that said in your position I didn't see the mate but I did see knight to h6 check and if the king goes to h file alternate the knight for the draw and if the king goes to f mate 1. needless to say black had options

Yes! And to be clear: Total respect to my opponent, who had me beat this game, though it was a crazy back and forth.

I've won being 14 points down recently. The real key is understanding the position and your counterplay chances. Also a lot of under 1500 players will stalemate. I was in a tournament last Friday and the player couldn't figure out a checkmate with a queen, and 3 minor peices and walked into a stalemate

On his defense, spotting the knight mate isn't really easy unless you actually already studied it previously. Although the perpetual checks possibility is quite obvious
I also never resign. I've learned my lesson in a game which I resigned although I had a strong feeling that I was winning, just couldn't figure out how - I was down A LOT of material, but my position was really good and my pieces were active. Later i've analyzed with the engine just to see that I was, in fact, completely winning - and it wasn't even that hard to spot, I just figured that with all the material I lost I couldn't win anymore... lol

I remember when I was below 1500 in a rapid game. I was hopelessly lost, but I saw a stalemate trick! Desperate, I played it, and he fell for it!

Indeed I had a game that ignoring the reflex to resign after a blunder ended up working out for me. After I went and blundered my queen (at least it was a complicated blunder - not a simple immediate capture - but a position where I found my queen attacked and all the escape options would lead to her capture). I played on - my opponent's pieces were surprisingly passive at that point and I found an attacking idea. Although I missed a mate in 1 within that attack, I was able to play to clear advantage and my opponent resigned (they were also behind on clock and position and material at the end). I was down a whopping 15 points of material after my queen blunder.

How did he miss the smothered mate??
1. ..Nh3++ 2. Kh1 Qg1+ 3. Rxg1 Nf2# seems obvious to me.
The obviousness of a thing like that depends a lot on having memorized the pattern. My opponent spent about two out of four minutes available calculating, but time pressure, seeing that I was so close to a mate, myself, and our overall low rating (he's at about 900 and I'm at about 800) added up to not seeing his own options. Since I've had a couple of club-level players say "Oh yeah, I wouldn't have seen that," it seems to me it's not obvious to everyone!
I wouldn't have seen it either, but I saw the first move, and it seems to me that spending those couple of minutes playing it out couldn't be any worse than a resignation (and would likely have given him a win.) He would have hit upon it just moving pieces and keeping me in check, most likely.
It's a pattern mate that's usually in the first chapter of any beginner's chess book. I show it to beginners at my local club fairly often, because it showcases the importance of the double-check.

Since he did not even go for a perpetual, I'd think he did not even realize that he had a discovered check.

guess its a low rated game, else i cant explain it. but sometimes you miss the easiest mates because you are just blind. happens ot all of us
Edit: as op is 800 rating i gues it was a low rated game. 800s usually dont see it unless they have seen it in the chess.com lesson guides already. but i think i have seen it first time at arround 900-1000
Yep. I play blind games once in a while with my friends and it becomes a simple but common mistake.

Actually no - I saw it the first time while looking at puzzles at some other site many years ago. I never learnt it when I had a rating of 1200+ at the time on yet another site. I never used a single chess book at all during that period of time.
