Hey Adam,
Here's some advice I'd give myself if I was able to when I started playing SNGMTTs
Playing loose early can make the rest of the tourney so much easier to play if you have good postfop skill. I like to get involved more in the pots with the bad players, but try really hard not to overplay strong of hands like AKo. It's ok to fold and only lose a small pot early. Play value, be aggressive, and fold when you get played back at. If a player keeps playing back at you, adjust to them.
Getting down to under 1000 chips isn't so bad. You'll just need one more double up than before. I've come back from small stacks, it's also good practice while you're at lower limits.
According to the coaches here, there's not really any strategy difference depending on the blind timing. The only difference is you'll have to be aware that the blinds rise fast, but they rise fast for everyone. Timing the blind level change so you end up on BU when it happens is a good way to use your time bank.
Don't steal too much even if card dead. You want to choose spots that are +EV according to ICM, or take necessary -EV spots occasionally. One of my favorite things to do is punish stealers and limpers esp. from the SB in BB.
Don't see cheap flops with random crap, but choose hands that play well postflop, like suited connectors you can call for multiway pots. you want to hit two pair or better. sometimes you can call light with a deceptive or strong draw, but you don't want to waste chips.
You'll get chances to push and call even if your cards are mediocre, everyone gets desperate when the blinds go up and start stealing much too wide from BU and SB for example.
A main consideration as the game gets later is relative chipstacks, and effective chipstacks of opponents. Watch out for smallstacks that are going to bust before you (e.g. tighten up) but don't be afraid to go for it on the final table. I'm shoving according to Nash and min-raise folding when I have a good stack.
I don't defend too loose if my stack is big, and rather wait for better spots. People don't really use ICM on these limits and call much too tight, and don't play back at your minraises enough, or if they do, they have a very strong hand.
Late game, I basically play ICM, but I also resteal from shorter stacks. You can apply a lot of pressure as you've hopefully built up your stack during the tourney. If not, you can still get away with FE for shoving 2-3BB at 500/1000 level.
The dynamics you get different chipstacks that you run into determine your ranges according to Nash equilibrium. of course you will adjust the Nash range depending on your opponents range. I highly recommend using an ICM calculator (get the holdem resources trial for example) to figure out what your ranges should be. I have been working on getting very familiar with them, and if you can apply and adjust them properly, you will prosper.
I've been following the blog of Target Me (Movin.Target) for a few years if you need some motivation, I would check out his results. He now plays 180man $8 and $3.50 rebuys and crushes it.
You have a good BR for $1.50, I think you should be easily profitable in them if you follow pokerstrategy coaches and articles. Most of all an ICM calcuator will be essential if you don't already use one. If you want to sweat a session let me know.
