STT basic strategy checklist

[Gravy (Gravy Smoothie)]

OK< starting to get a little bit of a feel for the Party $10/+$1 STT SNG's. Here's what I've got as a series of guidelines:

1) Play tight early: AA-JJ, AKs, AKo, AQs, AJs from EP, Axs, decent suited connectors, and AQ/AJ/KQ type hands in LP after limpers, pocket pairs in LP or if I think I can get in cheap.
2) Open up aggression when blinds hit 50/100. More blind steals and the like.
3) All-in or fold mindset with 8xBB or less. At 4xBB or less, looking for any pair, any Ace, most kings to push with.
4) If my stack is big enough to get into the money by playing tight, tighten up to Level 1-3 tightness standards and wait for the field to be limited to 3 people.

Obviously, no formula can capture optimal strategy, and these guidelines need to be adapted according to who's in the blinds, the table demeanor etc. etc.

How far off base am I?
