Depends mostly on my stack size...
Around 7bb-12bbs Im shoving a huge range in late position. A5s+, K7s+, Q10s+, All pairs,
67s+, basically. Also, Restealing with those hands and shoving over a late position raise that is likely stealing.
With a stack that can handle a few three bet and fold hands, I'm aggressive.
With a big stack I'm a freight train.
Right before the money hits is the absolute best time for me to pick up chips in most tournaments. Everyone tightens up and you can really rake in a lot of small pots. Once I get to the final table, with about 6-9 players left, I'm aggro again. Once Im down to the final few players, Im still aggro but a lot more careful.
