re: Poker & Turbo SnG's
Depends on the game.
I've played a lot of low-stakes turbos lately (single-table ones) and I've been getting pretty consistent results from them, but the standard and styles of play in them can vary wildly so you have to be ready to adjust.
In some of them, the play goes pretty quick, people are making big bets and raises and even though the levels are only three minutes long, you can lose four runners by the fourth level. In this case, you can usually just sit back and let the other players knock each other out.
In others, however, players don't even seem to acknowledge it's a turbo - you can sometimes come across tables where pretty much everyone's playing weak-tight, and you can build a decent stack just by making reasonable pre-flop raises and c-bets: you'll rarely see a showdown.
In either case, I've found staying out of trouble is imperative: if you limp into a lot of pots or call too many small raises, you'll be short on chips pretty quickly - often I won't even bother playing low-medium pairs for set value, because stacks are rarely deep enough to justify it. So I pretty much work with a "pump it or dump it" philosophy.
I think the major thing is you need to adjust your game to the table and opponents that you're given. Yes, they need a slightly different approach to a regular game, but I don't think they automatically negate the advantage a skilled player has.
