This is a revised post/idea from earlier since I couldn't edit the OP. I've already posted this word-for-word in the earlier thread, but I really think this is a much better subject line that explains my question using a more extreme situation. If this second post is against the rules, I apologize and understand if it gets deleted.

Let me specify the type of situation I'm thinking of at a greater extreme. Say you final-table a big sunday guaranteed which you entered through a satellite. Also, for sake of elaboration, 3rd place is 25X your bankroll and 1st is 50X (its a ton more than you have ). Yet any final finish is still a huge boost obviously. You and villain are basically tied for first. Early on you get involved in a hand in which you were a big favorite on the flop but are absolutely certain villain outdrew you on the turn (can we just say the cards are face-up?), yet you have a decent redraw. Lets say he caught two-pair and pushes while you have a straight-flush redraw to the nuts or a better two pair. This makes you ~2-1 dog in the following example.
(HERO: AsKd
villain: AcQd
flop: Ah Ts 9s
turn: Qs )


The pot is laying you better than 2-1, say 2.5 or 3-1, maybe more. Over half your chips are in the pot leaving you pot-committed in most situations. However, if you fold you still have a decent M, say 2-3 and you strongly believe you are the best at the table.
If somehow you are absolutely sure about your read do you take your good, maybe great odds and call an all-in on the draw, or fold and battle back. Are you pot-committed here? What percentage hit to your stack makes you pot-committed. How much overlay makes it an easy call/ I understand this is a crazy example and not sure if its actually possible for these pot-odds to occur (maybe there's tons of dead money in the pot) but I hope this illustrates my idea a little better. I am not saying this idea is correct, I'm asking for opinions on what the most practical play is or do you through practicality out the window. Keep in mind you are competing for a HUGE pay relative to your bankroll or networth for that matter. Do we use non-poker logic in this situation?
ABSOLUTELY HYPOTHETICAL!!!

ps. if you think this is a donkey situation please understand it is completely thought up to match my conditions. The fundamental question is how much overlay do you need when playing your biggest game ever? Also, I'm trying to think of an example where you aren't drawing with all your chips, but still, I hope this explains the magnitude and theme of the situation I imagine. (I wish this was the OP)
Gonna catch mad criticism on this one..
