i am currently reading HoH vol 2 and have a question about whether some of his theories about inflection points can be applied to pot limit tournies;

harrington seems to state that if you are short stacked in an NL tourny (lets say harringtons orange zone of 6-10x the pot) you should be looking for oprtunities to be the first player into the pot and when this opportunity presents itself you should move all in with a fairly wide range of holdings. you now have 3 ways to win, 1, all opponents fold, you are called and are favorite and win, you are called are an underdog and win.

lets say i have 9bbs in MP and hold ATs, all fold to me and i move all in, however if i am playing in a pot limit event i do not have the option of going all in. how would it be best to approach this situation?

in a recent PL tourny i had around T1500 in EP with blinds of 100/200, i was UTG with AQo and was unsure about how to handle the situation. do i raise the max then reraise all in? look to limp-reraise/limp call all of my chips etc?

EDIT, in the AQ hand i am new to the table so have no reads on other players.
