Is there "win hands up" too? Like to mean that someone wins a game very hard?

I see what you're saying! However, no, there isn't a "win hands up." another phrase you could use to mean winning a game, or doing something, with all of one's effort, is to "take all one has" to emphasize that it took a lot of effort, work, and energy to win or do something. Ex: It took all we had to win the basketball game. Ex: It took all she had to pass her maths exam, but she did it. Ex: He's going to win with his hands down. I'm sure.
