Unusual Hand vs. Allen Cunningham

[AJo Go All In]

Foxwoods 10k.

31 players left. The dealer starts dealing the cards and then floorman calls out "10 minute break." Immediately everyone gets up and leaves the table except for you and Allen Cunningham. Cunningham is on the button and you're in the big blind.

Both of you are confused and ask the dealer if the hand counts, the dealer confirms as you suspected that yes, the hand does count, and all the hands are dead except for yours and Allen's.

Okay, now, think. You know what has happened and you know that Allen knows and you know that Allen knows that you know and so on. The blinds are 3k/6k with a 1k ante, you have about 100k and Allen has about 500k. There is a $6,900 difference between 31st place and 30th.

Questions:

1. You don't say a word to Allen and just stare at him while he's looking at his cards.
a. Say Allen makes a standard raise to 20k. What range of hands do you move in/reraise with? What range do you call?
b. Say Allen pushes all-in. What range of hands do you call with?
c. Say Allen limps. What range of hands do you make a standard raise with? What range do you move in with?

2. This time you say "No shame in folding here Allen, I haven't looked but I'm liable to move in on you here," and he smiles and says "Yeah, you might be right" before looking at his cards.
Repeat questions a-c.
