Most profitable situations...

[perfectm]

A friend of mine was complaining about how whenever he gets a monster hand, his opponents have nothing and he never wins big pots. Which got us talking about ideal situations that pay off the best. Assuming equal stacks of opponents and NL structure, what do you think are the most profitable situations? (read: you're going to get all their money)

I always think the full house vs. nut flush is a big one, but the flush has to see that paired board and at least think its a possibility.

Straight flush vs. nut flush might be the best.

Set vs. Over pair

Set vs. TPTK

Set vs. Top (or any) 2 pair

Lets hear some others.
