I'm still not sure what the exact definition of the nuts is. Is the nuts the best hand possible, or simply what is almost certainly the best hand? For example if I start with Q 5, and the flop comes out Q Q 5, then I have the nuts. But if an 8 hits the turn, then is it no longer the nuts, or is it still the nuts since probably no one has Q 8? (depending on betting of course)
