Hands from the Bellagio ME when in a "short" stack

[PuertoKid]

There is a lot of missing information here, but going with just the information provided:

Hand 1: Fold. Unless UTG is "putting a move" on me, I have hard time believing I'm not beat. The only way to know that he isn't is to push, which is probably suicide.

Hand 2: That's a pretty big raise from MP. Very likely a "I'd like to take the blinds down w/o a fight" raise. You are very likely ahead here and this is probably a good spot to make some chips. I'd reraise to 3200.

Hand 3: Tough situation. 5900 in the pot and you have 7400 behind. A meaningful cbet here is at least 1/2 pot and that leaves you with 3500. How would you play this if you had JJ or QQ? I'd think about playing it the same way. There is nothing wrong with checking and seeing what develops either. I've seen you do exactly this in similar situations in online games.

Hand 4: I'd call 1500 for a pot of 2600 against MP here.
