couple of decisions for discussion

[wiggs73]

middle stages of online tourney... your stack is ~1500 and blinds are at 75-150. standard raise at the table is 450. You look at AK, AQ, AJ in middle position and it's folded to you. First decision, do you make a standard open raise of 450, or do you open push?

now, for the sake of argument, let's say you made a standard raise and got one caller from late position. Do you push any flop -or- check/fold to a flop that doesn't hit you and push to one that does?

how does holding 77-99, as opposed to ace-big, affect your play here?
