In games that I have won say R, B and N vs K or B and R vs K. People tend to resign, and I understand common chess etiquette is to resign and I do it as courtesy, but I feel that I want to learn how to FINISH a game. I know I am not that good overall but finishing after winning an advantage in the middle game is a glaring weakness.

How to you tell someone "hey let me try to finish instead of resigning" without coming off like a jerk? I want to work on getting to checkmate postion even in a clearly won game like Q and N vs K, B and 3 pawn islands.

Those endings can be long and some require a lot of concentration to avoid stalemate, so I agree that practice is good. However, I think that a computer is a better choice as an opponent, as it doesn't mind being whacked about for ten minutes until you finally put it out of its misery ;)

I know there are some chess.com videos and chess mentor lessons that show how to execute the common endings.

computer.... yea that would work huh? Guess I'm not as smart as I look

Thank you for the respones.

In case you haven't noticed, there is an option after your opponent resigns to play against the chess.com computer, I find that to be somewhat instructive.

Though I find that the majority of my opponents play to mate so often I wonder if they want me to play out to the mate instead of resigning when I know no hope is left.

 Are you implying that you look smart? If so, thanks.

 Thanks again I did not even see that! Maybe thats the key to making my chess better ..... paying attention!!
