Check Mate at low elo
I hate to say this, but it doesn't seem to get a whole better when you start to get better. Whenever I get an opponent who takes the "never resign" mantra way too far, it's often painful to look back on the game and notice how many times I missed a mate in 4 or less.
That might just be me, though. I suffer from chronic time trouble in endgames because I'm a real slowpoke.
