Explaining why minbetting isn't good

[Elandriel]

Hi all,

I'm having trouble explaining my brother why misraising almost always is a bad thing.

He was watching casino royale where bond minraises the rich guy to 2 million on the turn and i told him thats a bad move. He said yeah, maybe but not at those stakes cause it's a lot of money. Then i tried to explain it a little and he was like yeah stats whatever that is when you play 100s of hands and that doesnt work here.

What i need is a short sentence to use to explain why minraising is a bad thing.
