$16:Stealing Situations with blinds high

[austrian]

I picked out some spots of my last tournaments were i wasnt sure at:

Hand 1:

PokerStars Tournament, Big Blind is t200 (6 handed) Converter on pregopoker.com

UTG (t1950)
UTG+1 (t4410)
CO (t1338)
Hero (t2870)
SB (t1487)
BB (t1445)

Preflop: Hero is in Button with K[img]/images/graemlins/club.gif[/img] 2[img]/images/graemlins/spade.gif[/img]
<font color="gray">UTG folds</font>, <font color="gray">UTG+1 folds</font>, <font color="gray">CO folds</font>, <font color="red">Hero raises to t2870 (All-in)</font>

Pushing in these spot assuming the blinds are not to loose is standard right?
Which hands do u need to push?

Hand 2:

PokerStars Tournament, Big Blind is t400 with t25 antes (4 handed) Converter on pregopoker.com

CO (t3974)
Button (t4909)
SB (t1676)
Hero (t2941)

Preflop: Hero is in BB with 7[img]/images/graemlins/spade.gif[/img] K[img]/images/graemlins/spade.gif[/img]
<font color="gray">CO folds</font>, <font color="gray">Button folds</font>, <font color="red">SB raises to t1651 (All-in)</font>, <font color="gray">

Call or fold?

Hand 3:

<font color="gray">CO folds</font>, <font color="red">Button raises to t800</font>

Button is pretty aggresive,first mini raise though.Push or fold?

CO (t4952)
Hero (t2991)

Preflop: Hero is in Button with Q[img]/images/graemlins/diamond.gif[/img] T[img]/images/graemlins/diamond.gif[/img]

Presence of the small stack makes that an easy laydown right?
