HELP, my endgame is horrible.

Sigh, life is futile. Thanks to everyone that replied with an answer to my question. Thank you for the links LisaV.

Wow, thanks yeres30. That's cool.

18.Qe5+ with a quick mate

I can't look at this! The horror!
If you having trouble with checkmate and stalemate:

"If they are in check, it will not be stalemate."

So put them in check repeatedly? Maybe that'll eventually work for you! 

That sounds like a terrible idea Cliff.

Nietzsche, I'm not a very advanced player myself and other people have done a great job analysing your game. I just want to tell you forget about the sarcasm and insults. The first game I ever posted on the forums was when I was ranked in the 600s (now 1150s). I think two people out of ten or so actually tried to help me instead of giving a sarcastic or insulting response. So don't sweat it, you're getting a lot of good advice here.

Thanks Bellomy. I have a sense of humor, so I enjoy the sarcasm. I did get some great advice! Congrats on the improvements you've made! I'm probably about 600, but I have absolutely no clue. I can easily beat the computer on beginner, but lose everytime to easy, lol. However, I do see an improvement already thanks to the suggestions on this thread.
