Opponent only had their king left and didn't resign?

I'm very, very, very, much so a novice at this game, but I believe I read somewhere that just a king is insufficient material to win. I had my queen, king, and three pawns. They just kept dancing their king around the board instead of resigning or offering a draw. Was that bad sportsmanship on their part, or do I just not know enough about the game to know that what they did is totally fine?

Lower rated players are often told to never resign. Other similarly rated payers may stalemate their opponent when they have a lot more material or may not know how to mate with the material they have.

That's helpful to know. Thank you!

Dancing the King around is fine.

Offering a draw would be bad sportmanship in a situation like that in my opinion.

If the opponent has reason to believe a draw is possible, they may not resign right away. Sometimes lower rated players stalemate, sometimes they offer a draw if the game isn't going their way, sometimes they run out of time. And sometimes there could be a threefold repetition. All of those could be a draw even though the opponent only has a king.

They were successful. In this case they did get the draw so resigning would have been a mistake.

A Queen or Rook VS a King by itself cannot mate . . .

Your king has to support the mating piece . . .

Checking a king in the middle of the board is useless . . .

bring the king toward the other king and force it to the side . . .

DON'T GET STALEMATED . . .

A good practice exercise is put a king with a queen VS a lone King and try to mate it withing15 moves. . . When you can do that put a ROOK AND KING VS KING. . . .

tHE BEST BOOK FOR THAT IS . . .

An important advice to cakerbee: instead of giving 20 pointless check in a row, stop and think for a few seconds. What on Earth you were doing from move 54 to move 73?

This is all so helpful. Thank you all very, very much! I especially appreciate all the learning resources recommended.

Usually, it's to hope your opponent stalemates, so they keep dancing their king around. So just hope you don't stalemate and deliver checkmate.
