Hi from me as well
Thing is that in a 6-max SnG you rarely wanna limp as there are not many people to act behind and it's easier to represent a hand by raising than by limping. You can win the hand more that just one way...Meaning that even if you don't hit your set, you can still cbet on Axx board and get credit for it.
But ofc it's possible and I will still do it, say, we have 2 limpers and I am on the BTN with 22-55 and stack sizes of 40bb+. I am not raising as I expect the limpers to come along very often and I basically have to bluff on the flop almost always. Hand has no playability post. But first to act, my intention will be to always raise. If we get calls and we are deep-even better.
By limping you let yourself being exploited and a good reg is going to note your play and you can never be profitable against him. He can iso super wide range on the BTN f.e. and make a huge amount of chips ITLR.
