A common situation

[Seadood228]

I apologize if this has been discussed before, but it's kind of difficult to look for this particular situation..

Stack sizes

UTG - 2800
BT - 2500
SB (Hero) - 1900
BB - 800

Blinds 150/300

If it's folded to you, what's the LEAST you'd move in with in this spot? Assume that the BB is a decent player and will call with any two, especially because you've been moving in a lot. Also assume that the others will play a solid in future hands.

Now change the stack sizes to :

UTG - 3000
BT - 2800
SB (Hero) - 1400
BB - 800

How much more, if any, do your up your raising requirements?

Thanks.
