1) The issue here is, that while we are facing a jam from a short stack, we have two players behind with 3 times as many chips as the all-in player. This mean, that in a sense, if we give action here, we are risking 27BB to pick up 11-12BB by calling. This is a bad risk/reward, and we have no fold equity, so we need a pretty strong hand to get involved.
I dont know the theoretically correct answer (ICMizer does), but I would tend to fold here, unless I had a really premium hand. Maybe AJs+, AQ+, TT+. This might be to tight, but in a situation like this I will rather be overfolding slightly than the opposite. You still have plenty of times to look for better spots, and then it is ok to give up on one, which is very marginal and high variance, when you already have a perfectly workable stack.
I dont think, it makes a huge difference, if we just call or overjam, but I would tend to lean towards just calling. The reason is, I think, it can look like a trap, so it might actually get the blinds to fold a little more often. If someone call, we are protected postflop by the presense of the all-in player. He gives a disincentive for bluffing, so if we missed, we can usually just fold without making a mistake. And if we connected, we have a very easy get-it-in spot.
2) I guess, there is an argument for this following the same logic, which I applied to hypothetical flop play. Because of the all in player the value of bluff jamming goes way down, so if we get jammed on, we can usually assume, that the opponent was the goods. But even so I personally hate putting in a third of my chips without even seeing a flop, and since I would tend to only give action with very strong hands, I would probably always be calling it off.
3) Kind of answered that one under 1). I would play my entire range the same way and either call or overjam everything.
4) At this stage none. The bubble is still so far away, that the payout structure will not matter. When the bubble gets near, ICM-pressure is much higher in satellites, and this is the time, you need to start adjusting.
