wtf hell no. If your opponent has only a king, u have 50 moves to mate him or its a draw. Also 50 moves without capture or pawn push is also draw.
Draw?

It is 50 moves without capture or pawn push, nothing about bare kings.
By the way, it is not an automatic draw either, the player must claim it.
I have been playing chess so many years and one says to me something I didn't know:
"When a player eliminated all his partner pieces but the king, he has only 3 moves to do checkmate or the game is draw."
Is that true?
