Standard play at level 8?

[Sidekick]

Poker Stars $5 + $0.50 Sit and Go.

Table has been playing VERY tight. The only player other than myself that has been willing to take any risks has been the BB.

I have managed to fight my way back from about 600 chips when it was down to 5 players. Had a couple of good hands that went south to deplete my chips in level 4 which has left me in my current short stacked position.

BB has been the only player to show any real aggression besides myself since it got down to 5 players. I have been stealing blinds at slightly more than once every cycle, and managed to take down a couple of pots from the BB when someone limped, which has allowed me to build my stack up to where it is.

I think this is a routine play, but I have lost so many tournaments on hands like these lately that I need to verify that I'm making correct decisions.

All comments are greatly appreciated.
