I don't know what to say to you opponent. I better bite my lip.
Why I don't resign

Your opponent made a serious blunder. When you're in an endgame like that, always move your king off a weak back rank.

Excellent Mountainman! I'm all for not giving up until your king is dead! your opponent blundered big time when you were down... Good snatch of the game!!!

I had a friend of about equal strength that I swindled several times, turning losses into draws. One time I was dead lost and he decided he didn't have to pay attention anymore so he just promoted his pawn to a queen and was sure he would take down my king and lone pawn...but my pawn was a bishop pawn and his king was far enough away that I could get it to the 7th...and with his king just far enough away he could either keep checking me or let me promote=draw or he could capture my pawn at c2 with my king at a1=stalemate. So against him yeah I play on a bit lol.
Should you? It's okay to make him "prove" the win. If you know your opponent
you'll probably know when to resign, but be realistic.

Wow ur opponent could have forced checkmate with a rook and queen without having to bring the other rook up but I suppose since he can make a serious blunder like this He doesn't know how to =P
This should be a lesson to all those who resign when down a peice or two! there were several times when I thought It would soon be over and more then several when it could have been. I am a novice, mabey I got lucky, mabey I'm getting better, either way I played as black.
