Hi Roger,
I like the "hook" of the first one, I think it would stop more people in their tracks and get them to read the copy.
But the third headline stresses the finality of the situation. One shot and you're out. I think that's important for the target market who is looking to win, at that moment, at all costs.
If I had to fall of the fence and choose one, I'd go with the first. Better hook, so I think more people read on.
Just my 2 cents
