Tournament theory question

[Dolus]

Hypothetical tournament questions.

The following questions assumes a nl tournament with no rebuys having all players P play at the same caliber (no player is better than the other).This tournament allows all players 2 distinct buy in options. No player knows in advance how the others choose. Which option is better for player Pn.

Tournament A

option 1 buy in: $100 chips: T1000
option 2 buy in: $200 chips: T2000

Q1- which option is better in a multi-payout format?
Q2- which option is better in a winner take all format?

Tournament B

option 1 buy in: $100 chips: T1000
option 2 buy in: $200 chips: T3000

Q3- which option is better in a multi-pay out format?
Q4- which option is better in a winner take all format?

Q1: 1. Because of the multi-payout structure, the more chips you have, the less each one is worth. Short-stacks have two additional advantages: (1) bigger stacks' strategies will be much more focused on winning money from one another causing them to play suboptimally relative to you, and (2) when you're all-in, players who might have drawn out on you will sometimes fold as a result of bets that happen after you're already all-in.
Q2: 1, but it's not as big a difference when you don't have the multi-payouts and only have the latter two advantages.
Q3: 2. The extra 50% in chip value far outweighs the small considerations above. If it was something like 2100, then probably 1.
Q4: 2.

In a re-buy tournament if the re-buy's are significantly less than the original buy in, should you be willing to take slightly the worst of it in a hand if loosing that hand will give you the option to re-buy?

scenario: $100 buy in, $1 re-buy

first hand you have AKo in the BB it gets folded around to the SB who has QQ. SB pushes all in and shows his hand. Do you call?

Easy all in, in that situation, I would be willing to take much much worse. I.E. 78s all in vs AA. thats a severe gap though.
