What Hand did Teddy KGB have at the end of Rounders

[top6]

was Teddy going to kill Mike if he had lost? It sure seemed that way to me. Of course, this makes little sense - why wouldn't he just make Mike play poker for him to pay him off. But I always assumed from the way everyone was talking that Mike would be killed if he couldn't pay them.

If that's the case, is there a worse tell in the world than Mike saying, "if I don't call, I won't be able to live with myself tomorrow"? I mean, talking about tomorrow when you will be dead if you lose seems to me a dead give away that you have the nuts.
