This concept has been working its way around my head for a while, so I thought I'd get your ideas on it.

This is the beginning of a hand I played in a live 2/5 game:
9-handed, I'm on the BB, the table is fairly good skill-wise, with maybe a rock and a bunch of medium-loose agros and laggs. UTG folds, everyone else limps for 5. So the pot is $45 and if I rap on the table we see a flop.

I make it $80 to go, so $75 more to everyone at the table.
What hand I had specifically isn't really important to this discussion, the hand ended very badly for me, but the concept is what I'm talking about.

Say the table is more taggy, and the raise is $45 instead of $75 more, that way it's $45 to call into a $90 pot. Some of the time you take the pot down, more of the time you isolate against one or two players, and 1/3 of the pot is just dead money, giving you lots of extra equity. What kind of a hand do you need to make this move? What if you're on the button or the cutoff?
