Early in an SnG at Doylesroom.

I have JJ in the SB.

3 Limpers and BB yet to act.

I...

I'm not familar with their structure. How many times the BB do you start with? How fast do the blinds go up?

Assuming you start with something like 75 times the BB, I actually really don't mind just a limp here. You're out of position for the rest of the hand and it's a good time to try and trap someone for all their chips if you flop a set instead of raising and winning these relatively small blinds (or raising, getting called, and playing a post-flop guessing game when an overcard or two flops).

At Doyles room you get a lot of experienced Euro no limit players who dont know the difference between a tourney and a ring game. As such you get a ton of limpers with anything promising, and they will almost certainly all fold. (In fact I'd be tempted to push with almost any hand here).

If you get a caller it is probably an Ax and youre a solid favorite.

you limp.

Already 3 pple in behind you, its earlyyyyyy, you are in the worst position ever. If you raise youd have to make it substantial to try and get it heads up or take it down, if you do make substantial raise and get a caller you are almost certaintly against overs and then if any akq hits you are done withthe hnd and your stack is severely hurt.

Limp, no one has any clue how strong you are with a limp, I limp to protect myself from making a big pot with such a weak holding and to possibly win a big hand with a trap on the flop. If you see all unders I would probably limp and checkraise a lot to try and take pot down then or to be willing to get it all in against top pair or be willing to pay off 2 pair or set.

I hope that makes sense, I limp preflop because I dont want a pot building too early in the hand and then I checkraise because JJ is very strong hand when unders come and I am no longer weary of playing a big hand after seeing 3/5 of the board.

If your M is large, you limp for set value. If you become an overpair, play aggressively, but fold if it's clear you're losing.

If your M is small, you push.

I would probably make a standard raise here, and hope to get a HU pot, or at least thin the field. If an overcard hits, bet out on the flop and play accordingly. If no overcard hits, you likely have the best hand, and bet the flop for value.

He said that it was early in the game. So why push here? To take down the limps? Then people talking about M here, you already know that he basically told you that he has a super high M (since it is early in tourney we can assume blinds are low and since there are only limps to him is M should be pretty darn high).

Just limp, you wanna win a big pot here or fold them later to overs and lose practically nothing.

I apologize, I was reading two different threads and mixed the two stories. I still stand by my answer, just had to edit what i got mixed up.

Except for the part where he didn't give the structure, the stack sizes or the current pot size.

Other than being incorrect, you're right!
