I think the OP meant when you hit mid pair on the board but damn that's some solid advice right there. This is exactly how I'm thinking when planning my play. When you say calling is ok, would you still call a bunch of limpers if you are let's say somewhere in the mid positions or would you rather raise with a drawing hand?
Whoops, you're right. I misread. Sorry.
To answer the OP, what I "try" to do is perform a 3-barrel
bluff where I'm pretending to have top pair, weak kicker. Bet a few BBs on the flop, bet 1/4th on the turn, then when the river comes push big (like the pot) hoping they think you hit two pair on the river. Of course, that's assuming they don't actually have the han you're "
bluffing with".
But to answer your question, the more limpers you have the more likely it is you'd get called if you raised. So if you want to build a pot in the hopes of getting lucky, raising would be good.
I'd consider folding more in that situation though. Throwing the mid pocket pair away would be a good move given the
odds of a higher pair hitting become greater if you can't kick everyone out of the hand.
Unless there are so many limpers that your
pot odds are through the roof. Then I'd call just to see a flop (since you're never going to kick everyone out of the hand in that case).
