I've been playing at these levels for a while now, and I'm about to move up.
What I've found is that you need to play very tight and straightforward poker. You will encounter mostly bad or mediocre players, so don't try to get fancy.
Here are a few rules that have worked for me in SNGs.
- I play very few hands, depending on my position maybe down to A10s. Maintaining this tight image gives me quite a bit of freedom expecially at the later stages because people will respect my raises and I can often get away with raising weaker hands.
- In 95% of all cases I raise preflop instead of limping, I try to make the raise a consistant 3.5x - 4x the BB. I don't vary the bet based on the strength of my hand
- I hardly every call all-ins except if a) I have KK or AA b) I'm already in the money and have a good hand c) I have a much larger stack and a reasonable chance of kicking the smaller stack out.
- If I opened pre-flop I will almost always make a bet on the flop, no matter if I hit the flop or not
- Once the table gets shorthanded (4 players and less) I play extremely aggressively. I'll raise a lot because I know that at this stage everybody becomes scared of losing chips. You can steal a ton of blinds at this stage. If I do get called, I keep betting hard at the flop. Considering that the other player probably missed it, it doesn't even matter whether I missed it myself.
These are some of the things that have worked really well for me.
In general, I just find it very important to avoid gambling.
Very often, players tend to go all-in even at the tiniest blind levels. There's not a single hand with which I'd do that, it's pointless.
