I guess the biggest or best strategy I have found is just folding like a mad man early on. Unless I have a very good hand, I will fold like crazy and let the morons at the table take each other out. I ALWAYS see people go all in with junk and basically wait on them to get rid of each other. That takes the table of 9 players down to 5 or 6 and then I'll start playing my 'normal' game.
Another thing: Once we're down to 5 or 6 people, if I'm in on a hand and somebody moves all in, I will always fold unless I'm holding A-A basically. By this time, there are usually shorter stacks or at least 1 large stack that will call the all in and I just hope to see 1 more person disappear and take the table down to one less person.
Really, everything else is situational but these are two things that I do every time. Yes, it makes the game pretty boring for awhile when it starts, but the strategy takes a 9 person table down to 4 or 5 people and the top 3 will make money. Of course my goal is to finish 1st, but hitting the money a large percentage of the time is more realistic and you're still making money that way. Also, you can count on the morons to eliminate each other and make your odds better. It's like clockwork. A lot of those people shove right away, and do it often, because their strategy is to double up their stack right away or just get the hell out of the tournament. So either they have money to waste or they are too stupid to realize how much money they are actually losing. Quite honestly, I depend on hitting just 1 or possibly 2 pots and most of the time that will get me down to the final 4 at the table. Then it's a matter of 1 person leaving before you are guaranteed money. The only bad thing about this strategy is that I usually find myself up against a larger stack when it comes time to play heads up, however, one nice hand can even the stacks up and you're already making money by then.
So any other strategies or tips that work for you in SnGs in particular? this is most likely what I'll be playing since rakes aren't involved and I honestly trust the software more since they make their money with the buy in, up front. You can't make money as fast, but if you play multi tables and do turbos and finish in the top 3 on a regular basis, you can make pretty decent money per hour. I figure being up even just $20 or $30 per hour on $6.50 SnGs multi tables isn't too bad at all.
