So the question for debate is, when should you open-push all-in in the later stages of an MTT?

IMHO ....
- The key question is whether or not you are already in the money, and do you need a significant stack increase to either make the money or move up well into the money.
- Another is the table mentality. Have people been open pushing and only getting the blinds? Have people been getting called down?
- Another is how many players at the table, and do you really want to get called, or would you be happy with just the blinds?
- I also agree with another response that your M is too high for open pushing here. With anything less than AA, KK, QQ, I want some opponents in the hand to extract some chips from them when my hand holds up. With anything less, I want some opponents in the hand to give me enough odds to play the hand after the flop if warranted.

I generally agree with something CSC said a while back, something to the effect of "preflop all in is the most vulgar form of poker." I'm not opposed to open pushing altogether. I just think it is more situational than random.

There needs to be a reason for every bet. Random open pushing with no rhyme or reason instead of playing poker on the flop, is like running across the interstate to save 5 minutes, instead of taking 10 and using the overpass. You might save the time cutting across, but you might also run into a truck. On the other hand, walking across the overpass will also get you there, albeit a little later, but almost always safe and sound.
