2) This is a $3.25, so the quality of play is marginally better than at $1.10 but by no means stellar. I would not be surprised to get a call from someone as wide as any PP, Ax, KQ, KJs, maybe even QJs. That being said, I have noticed that these loose calls are less frequent than at $1.10
JT and T9 are calling your ass, too. Which is
very good, but something you need to be aware of. Another factor to consider is you are in the CO of an unopened pot, which widens calling ranges significantly if these guys haven't read HOH recently. Your shove smells a lot like a steal/desperation in this spot, I wouldn't count on AJ+/66+ in this case.
3) Since I just recently moved up from $1.10 to $3.25 45-turbos, I've decided to focus on cashing until I get my sea legs at the new buy-in. Regardless, though, once we get to the bubble I will always play to cash at that point even if my overall strategy is to go deep. I absolutely hate bubbling in 45-man SnGs.
you are not alone in this thought, believe me. While I agree with Copernicus about abusing the bubble, there isn't a single player left to act behind you that you are "forcing to make a decision for their tournament life". This is very important to the decision making process. You can cripple anyone, but no one acting behind you is looking at the tourney lobby after the hand.
4) Cappy, I've been thinking about the same thing lately. Given that people at these micro levels love to call pushes with Aces, would I rather see something like JT here than A7?
You'd rather cash and not have to worry about it. If you claim anything else, you're lying.

But yeah, the only value in A7 is folding out those left to act, which makes A7 about as powerful as 52 in this situation. The rare times we fold them out does not offset the time you are called by better/dominated/flipping on the bubble. If this isn't a turbo, I'd be more inclined to raise/push, simply because you don't look nearly as desperate if your M actually means something.
