My victory when i might had defeat

In this game i have the first case of victory without queen in all endgame long. Fortunately, my opponent was thinkig so slowly, and i had won him/her with many time. i didn't give up when he/she had made queen. And now, i know that we haven't problems, that haven't decisions.
Never give up, even if everything is very bad. Some time for thoughtful mood and you win when you may have defeat
