Could have been asked before . is there a strategy of Limp/ raise in ep or mp

It is possible to construct a winning limping strategy from ep and mp. But todays games are very aggressive, so it is no easy task. You have to overcome a positional disadvantage and not having the betting lead. The pots you win will also be smaller on average.

I'd have to disagree with this part. Your opponents will isolate with a wider range than they'd call your raise with. So if your limp doesn't get raised, the pot wouldn't be any smaller, because they would all have just folded anyway if you raised. [Exception might be if the majority of other players at the table are passive fish]. So considering there is postflop play (after you limp), the pots will either be the same size, or bigger.

However, if someone iso-raises your limp, their raise size will typically be bigger than a normal open-raise size. So the pots will be bigger. Plus, you have the option to 3-bet now, to make the pot even bigger. So I would say the pots would be bigger on average.

I'm not advocating limping by the way. I've experimented a bit with that in the past, and I'm neither for, nor against it. I think it could be part of a winning strategy, but probably more difficult to do so.

Yeah there are many different limping strategies in EP. People lose tons of money with it every single day.

<------Exhibit A

Except in the absolutely softest games against subhumans (aka live games in the pub), limping in EP will never be as profitable as using a 'raise or fold' strategy. A huge part of your winnings come from blind steals (even from early position). No one ever stole the blinds by limping.

My limp strategy is don't limp!
