How should I play against people who limp every hand and call down? SNG

My advice is to just sit and wait until the third or fourth blind level before you start playing any hands. That way you'll build a tight table image and you'll also get to see who the donkeys are and who the good players are. And in sit and go's there are usually 1 or 2 players that are eliminated early on so it's better to let someone else play against the donks that early instead of you risking your stack for 22 chips.

best way to play it is to limp in and look just as loose as they are. just learn to only play flops that you hit big or have the potential to be big. as long as you look loose as they are they won't mind loosing there chips, because they will just think you got lucky, but you really just playing really good post flop poker.

Even though it's crazy that almost everyone calls a pf raise, you still have to do it. Raise to 100, and you will surely get one or two players out that may have limped in. Then, choose your spot carefully to bet after the flop. If you catch something, you're now in good position to earn some chips. If you don't raise pf and catch something, there aren't enough chips in the pot to go after. And be prepared to get out after the flop if you didn't hit. I play a live freeroll so you can imagine there are a lot of callers. I find that a substantial preflop raise, over time, benefits me if I'm patient and careful.
