When you analyze deep into it, MTT and SnG strategy are very different, specifically bubble strategy.
In MTTs you shouldn't tighten your game too much when you get near the bubble if you want to maximize your EV, since it's more important to get a larger stack and bully medium/short stacks so you can final table more often to win the big money then to be worried about busting.
If you want to be a successful SnG player, however, you must understand the dynamics of bubble play and ICMs. Very synthetically, if top 3 are paid and there are 4 remaining there are times when folding premium hands like JJ, QQ, AK and even KK are the correct play. Say, hypothetically, you have 6000 chips, and the other 3 have 6500, 1500 and 1000; you're on the BB with JJ, it's folded to the big stack on the SB and he puts you all in with 200/400 blinds. You should fold in this spot (even if you KNOW he's pushing any 2 cards) because you're not winning enough times to be +EV on the long run, since one of the short stacks is bound to bust soon and put you in the money.
Hope it helped someone... and that I didn't say anything wrong! =)
