I was just curious of the odds on this occurrance...

I have pocket 7s, and there's one player left with me. The flop comes KK7, and I bet -- to which he pushes, and I do the same.

They flip over KQ.

So, at this point, here's the breakdown:

Me: 77
Them: KQ
Flop: KK7

What are the odds of each party winning?

Best,
EW

PS - Obviously, I don't have to tell you the ending.
